How do I change the placeholder text color of a UITextField through Swift? I can’t seem to access the placeholder attribute. Thanks

asked Dec 29, 2014 at 4:25

You can set the placeholder text using an Attributed string. Set color to attributes
Property.

   textField.attributedPlaceholder = NSAttributedString(string:"placeholder text",
   attributes:[NSForegroundColorAttributeName: UIColor.yellowColor()])

Swift 5

textField.attributedPlaceholder = NSAttributedString(string:"placeholder text", attributes:[NSAttributedString.Key.foregroundColor: UIColor.yellow])

You can create Subclass of Textfield and can override DrawRect function of textfield.
By creating subclass you can set that for every textfields Easily.

class CustomTextfield :UITextField {
 override func drawRect(rect: CGRect) {
self.attributedPlaceholder = NSAttributedString(string:self.placeholder != nil ? self.placeholder! : "", attributes:[NSForegroundColorAttributeName: UIColor.grayColor()])
} }

In this tutorial you will learn how to change the color of a UITextField’s placeholder text. This is a straight forward task but if you are anything like me and you see NSAttributedString you start looking for a different solution. We are going to be using NSAttributedString in this tutorial, but it is very basic and easy for what we need to do.

Before we start, I am going to assume that you have a text field set up. If not, you will need a text field set up for this tutorial.

I have a text field outlet and I will be using the attributed string to change the color in the didSet property observer. Update your text field outlet to look like this:

@IBOutlet weak var textField: UITextField! {
    didSet {
        let redPlaceholderText = NSAttributedString(string: "My Placeholder",
                                                    attributes: [NSAttributedString.Key.foregroundColor: UIColor.red])
        
        textField.attributedPlaceholder = redPlaceholderText
    }
}

As mentioned before, this is a very simple attributed string. All we have done is create a new variable and assigned a new instance of NSAttributedString to it. The first argument of the attributed string is the string we want to display, and the second argument is for the attributes we want to use.

In the above example we are only using the .foregroundColor attribute and setting it to UIColor.red for simplicity. You could make this any color you want.

The last thing that we have done is used the attributedPlaceholder property instead of the normal placeholder property. This will allow us to assign an attributed string as the placeholder text.

If you do not have the text field as an outlet, you could create a function that will assign the attributed string to the text field as we have done in the code.

Conclusion

Using an attributed string is actually quite simple, even if it does seem daunting at first. There are quite a few options that an attributed string will allow you to customise, such as the font, stroke color, stroke width, kern etc.

If you want to see my full source code, you can find it here.

Since the introduction of attributed strings in UIViews in iOS 6, it’s possible to assign a color to the placeholder text like this:

if ([textField respondsToSelector:@selector(setAttributedPlaceholder:)]) {
  UIColor *color = [UIColor blackColor];
  textField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:placeholderText attributes:@{NSForegroundColorAttributeName: color}];
} else {
  NSLog(@"Cannot set placeholder text's color, because deployment target is earlier than iOS 6.0");
  // TODO: Add fall-back code to set placeholder color.
}

You can override drawPlaceholderInRect:(CGRect)rect as such to manually render the placeholder text:

- (void) drawPlaceholderInRect:(CGRect)rect {
    [[UIColor blueColor] setFill];
    [[self placeholder] drawInRect:rect withFont:[UIFont systemFontOfSize:16]];
}

This works in Swift <3.0:

myTextField.attributedPlaceholder = 
NSAttributedString(string: "placeholder text", attributes: [NSForegroundColorAttributeName : UIColor.redColor()])

Tested in iOS 8.2 and iOS 8.3 beta 4.

Swift 3:

myTextfield.attributedPlaceholder =
NSAttributedString(string: "placeholder text", attributes: [NSForegroundColorAttributeName : UIColor.red])

Swift 4:

myTextfield.attributedPlaceholder =
NSAttributedString(string: "placeholder text", attributes: [NSAttributedStringKey.foregroundColor: UIColor.red])

Maybe you want to try this way, but Apple might warn you about accessing private ivar:

[self.myTextField setValue:[UIColor darkGrayColor] 
                forKeyPath:@"_placeholderLabel.textColor"];

NOTE
This is not working on iOS 7 anymore, according to Martin Alléus.

Swift 3.0 + Storyboard

In order to change placeholder color in storyboard, create an extension with next code. (feel free to update this code, if you think, it can be clearer and safer).

extension UITextField {
    @IBInspectable var placeholderColor: UIColor {
        get {
            guard let currentAttributedPlaceholderColor = attributedPlaceholder?.attribute(NSForegroundColorAttributeName, at: 0, effectiveRange: nil) as? UIColor else { return UIColor.clear }
            return currentAttributedPlaceholderColor
        }
        set {
            guard let currentAttributedString = attributedPlaceholder else { return }
            let attributes = [NSForegroundColorAttributeName : newValue]

            attributedPlaceholder = NSAttributedString(string: currentAttributedString.string, attributes: attributes)
        }
    }
}

Swift 4 version

extension UITextField {
    @IBInspectable var placeholderColor: UIColor {
        get {
            return attributedPlaceholder?.attribute(.foregroundColor, at: 0, effectiveRange: nil) as? UIColor ?? .clear
        }
        set {
            guard let attributedPlaceholder = attributedPlaceholder else { return }
            let attributes: [NSAttributedStringKey: UIColor] = [.foregroundColor: newValue]
            self.attributedPlaceholder = NSAttributedString(string: attributedPlaceholder.string, attributes: attributes)
        }
    }
}

Swift 5 version

extension UITextField {
    @IBInspectable var placeholderColor: UIColor {
        get {
            return attributedPlaceholder?.attribute(.foregroundColor, at: 0, effectiveRange: nil) as? UIColor ?? .clear
        }
        set {
            guard let attributedPlaceholder = attributedPlaceholder else { return }
            let attributes: [NSAttributedString.Key: UIColor] = [.foregroundColor: newValue]
            self.attributedPlaceholder = NSAttributedString(string: attributedPlaceholder.string, attributes: attributes)
        }

I had already faced this issue. In my case below code is correct.

Objective C

[textField setValue:[UIColor whiteColor] forKeyPath:@"_placeholderLabel.textColor"];

For Swift 4.X

tf_mobile.setValue(UIColor.white, forKeyPath: "_placeholderLabel.textColor")

For iOS 13 Swift Code

tf_mobile.attributedPlaceholder = NSAttributedString(string:"PlaceHolder Text", attributes: [NSAttributedString.Key.foregroundColor: UIColor.red])

You can also use below code for iOS 13

let iVar = class_getInstanceVariable(UITextField.self, "_placeholderLabel")!
let placeholderLabel = object_getIvar(tf_mobile, iVar) as! UILabel
placeholderLabel.textColor = .red

Hope, this may help you.

iOS 6 and later offers attributedPlaceholder on UITextField.
iOS 3.2 and later offers setAttributes:range: on NSMutableAttributedString.

You can do the following:

NSMutableAttributedString *ms = [[NSMutableAttributedString alloc] initWithString:self.yourInput.placeholder];
UIFont *placeholderFont = self.yourInput.font;
NSRange fullRange = NSMakeRange(0, ms.length);
NSDictionary *newProps = @{NSForegroundColorAttributeName:[UIColor yourColor], NSFontAttributeName:placeholderFont};
[ms setAttributes:newProps range:fullRange];
self.yourInput.attributedPlaceholder = ms;

To handle both vertical and horizontal alignment as well as color of placeholder in iOS7. drawInRect and drawAtPoint no longer use current context fillColor.

https://developer.apple.com/library/ios/documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/CustomTextProcessing/CustomTextProcessing.html

Obj-C

@interface CustomPlaceHolderTextColorTextField : UITextField

@end


@implementation CustomPlaceHolderTextColorTextField : UITextField


-(void) drawPlaceholderInRect:(CGRect)rect  {
    if (self.placeholder) {
        // color of placeholder text
        UIColor *placeHolderTextColor = [UIColor redColor];

        CGSize drawSize = [self.placeholder sizeWithAttributes:[NSDictionary dictionaryWithObject:self.font forKey:NSFontAttributeName]];
        CGRect drawRect = rect;

        // verticially align text
        drawRect.origin.y = (rect.size.height - drawSize.height) * 0.5;

        // set alignment
        NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
        paragraphStyle.alignment = self.textAlignment;

        // dictionary of attributes, font, paragraphstyle, and color
        NSDictionary *drawAttributes = @{NSFontAttributeName: self.font,

        [attrString setAttributes: @{NSForegroundColorAttributeName: color} range: NSMakeRange(0,  attrString.length)];
        self.attributedPlaceholder =  attrString;
    }
}

- (UIColor*) placeholderColor {
    return [self.attributedPlaceholder attribute: NSForegroundColorAttributeName atIndex: 0 effectiveRange: NULL];
}

Swift 5 WITH CAVEAT.

let attributes = [ NSAttributedString.Key.foregroundColor: UIColor.someColor ]
let placeHolderString = NSAttributedString(string: "DON'T_DELETE", attributes: attributes)
txtField.attributedPlaceholder = placeHolderString

The caveat being that you MUST enter a non-empty String where «DON’T_DELETE» is, even if that string is set in code elsewhere. Might save you five minutes of head-sctratching.

if subclassing you MUST do it in layoutSubviews (not in init)
strangely you do NOT have to clear the normal placeholder. it knows to not draw placeholder if you’re using the attributed placeholder.

Overriding drawPlaceholderInRect: would be the correct way, but it does not work due to a bug in the API (or the documentation).

The method never gets called on an UITextField.

See also drawTextInRect on UITextField not called

You might use digdog’s solution. As I am not sure if that gets past Apples review, I chose a different solution: Overlay the text field with my own label which imitates the placeholder behaviour.

This is a bit messy though.
The code looks like this (Note I am doing this inside a subclass of TextField):

@implementation PlaceholderChangingTextField

- (void) changePlaceholderColor:(UIColor*)color
{    
    // Need to place the overlay placeholder exactly above the original placeholder
    UILabel *overlayPlaceholderLabel = [[[UILabel alloc] initWithFrame:CGRectMake(self.frame.origin.x + 8, self.frame.origin.y + 4, self.frame.size.width - 16, self.frame.size.height - 8)] autorelease];
    overlayPlaceholderLabel.backgroundColor = [UIColor whiteColor];
    overlayPlaceholderLabel.opaque = YES;
    overlayPlaceholderLabel.text = self.placeholder;
    overlayPlaceholderLabel.textColor = color;
    overlayPlaceholderLabel.font = self.font;
    // Need to add it to the superview, as otherwise we cannot overlay the buildin text label.
    [self.superview addSubview:overlayPlaceholderLabel];
    self.placeholder = nil;
}

Iam new to xcode and i found a way around to the same effect.

I placed a uilabel in place of place holder with the desired format and hide it in

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
    switch (textField.tag)
    {
        case 0:
            lblUserName.hidden=YES;
            break;

        case 1:
            lblPassword.hidden=YES;
            break;
 
        default:
            break;
    }
}

I agree its a work around and not a real solution but the effect was same got it from this link

NOTE: Still works on iOS 7

I needed to keep the placeholder alignment so adam’s answer was not enough for me.

To solve this I used a small variation that I hope will help some of you too:

- (void) drawPlaceholderInRect:(CGRect)rect {
    //search field placeholder color
    UIColor* color = [UIColor whiteColor];

    [color setFill];
    [self.placeholder drawInRect:rect withFont:self.font lineBreakMode:UILineBreakModeTailTruncation alignment:self.textAlignment];

Another option that doesn’t require subclassing — leave placeholder blank, and put a label on top of edit button. Manage the label just like you would manage the placeholder (clearing once user inputs anything..)

Since the introduction of attributed strings in UIViews in iOS 6, it’s possible to assign a color to the placeholder text like this:

if ([textField respondsToSelector:@selector(setAttributedPlaceholder:)]) {
  UIColor *color = [UIColor blackColor];
  textField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:placeholderText attributes:@{NSForegroundColorAttributeName: color}];
} else {
  NSLog(@"Cannot set placeholder text's color, because deployment target is earlier than iOS 6.0");
  // TODO: Add fall-back code to set placeholder color.
}

You can override drawPlaceholderInRect:(CGRect)rect as such to manually render the placeholder text:

- (void) drawPlaceholderInRect:(CGRect)rect {
    [[UIColor blueColor] setFill];
    [[self placeholder] drawInRect:rect withFont:[UIFont systemFontOfSize:16]];
}

Swift 3.0 + Storyboard

In order to change placeholder color in storyboard, create an extension with next code. (feel free to update this code, if you think, it can be clearer and safer).

extension UITextField {
    @IBInspectable var placeholderColor: UIColor {
        get {
            guard let currentAttributedPlaceholderColor = attributedPlaceholder?.attribute(NSForegroundColorAttributeName, at: 0, effectiveRange: nil) as? UIColor else { return UIColor.clear }
            return currentAttributedPlaceholderColor
        }
        set {
            guard let currentAttributedString = attributedPlaceholder else { return }
            let attributes = [NSForegroundColorAttributeName : newValue]

            attributedPlaceholder = NSAttributedString(string: currentAttributedString.string, attributes: attributes)
        }
    }
}

Swift 4 version

extension UITextField {
    @IBInspectable var placeholderColor: UIColor {
        get {
            return attributedPlaceholder?.attribute(.foregroundColor, at: 0, effectiveRange: nil) as? UIColor ?? .clear
        }
        set {
            guard let attributedPlaceholder = attributedPlaceholder else { return }
            let attributes: [NSAttributedStringKey: UIColor] = [.foregroundColor: newValue]
            self.attributedPlaceholder = NSAttributedString(string: attributedPlaceholder.string, attributes: attributes)
        }
    }
}

Swift 5 version

extension UITextField {
    @IBInspectable var placeholderColor: UIColor {
        get {
            return attributedPlaceholder?.attribute(.foregroundColor, at: 0, effectiveRange: nil) as? UIColor ?? .clear

I had already faced this issue. In my case below code is correct.

[textField setValue:[UIColor whiteColor] forKeyPath:@"_placeholderLabel.textColor"];

For Swift 4.X

tf_mobile.setValue(UIColor.white, forKeyPath: "_placeholderLabel.textColor")

For iOS 13 Swift Code

tf_mobile.attributedPlaceholder = NSAttributedString(string:"PlaceHolder Text", attributes: [NSAttributedString.Key.foregroundColor: UIColor.red])

You can also use below code for iOS 13

let iVar = class_getInstanceVariable(UITextField.self, "_placeholderLabel")!
let placeholderLabel = object_getIvar(tf_mobile, iVar) as! UILabel
placeholderLabel.textColor = .red

Hope, this may help you.

To handle both vertical and horizontal alignment as well as color of placeholder in iOS7. drawInRect and drawAtPoint no longer use current context fillColor.

        CGSize drawSize = [self.placeholder sizeWithAttributes:[NSDictionary dictionaryWithObject:self.font forKey:NSFontAttributeName]];
        CGRect drawRect = rect;

Swift 5 WITH CAVEAT.

let attributes = [ NSAttributedString.Key.foregroundColor: UIColor.someColor ]
let placeHolderString = NSAttributedString(string: "DON'T_DELETE", attributes: attributes)
txtField.attributedPlaceholder = placeHolderString

The caveat being that you MUST enter a non-empty String where «DON’T_DELETE» is, even if that string is set in code elsewhere. Might save you five minutes of head-sctratching.

if subclassing you MUST do it in layoutSubviews (not in init)
strangely you do NOT have to clear the normal placeholder. it knows to not draw placeholder if you’re using the attributed placeholder.

Overriding drawPlaceholderInRect: would be the correct way, but it does not work due to a bug in the API (or the documentation).

The method never gets called on an UITextField.

See also drawTextInRect on UITextField not called

You might use digdog’s solution. As I am not sure if that gets past Apples review, I chose a different solution: Overlay the text field with my own label which imitates the placeholder behaviour.

This is a bit messy though.
The code looks like this (Note I am doing this inside a subclass of TextField):

@implementation PlaceholderChangingTextField

- (void) changePlaceholderColor:(UIColor*)color
{    
    // Need to place the overlay placeholder exactly above the original placeholder
    UILabel *overlayPlaceholderLabel = [[[UILabel alloc] initWithFrame:CGRectMake(self.frame.origin.x + 8, self.frame.origin.y + 4, self.frame.size.width - 16, self.frame.size.height - 8)] autorelease];
    overlayPlaceholderLabel.backgroundColor = [UIColor whiteColor];
    overlayPlaceholderLabel.opaque = YES;
    overlayPlaceholderLabel.text = self.placeholder;
    overlayPlaceholderLabel.textColor = color;
    overlayPlaceholderLabel.font = self.font;
    // Need to add it to the superview, as otherwise we cannot overlay the buildin text label.
    [self.superview addSubview:overlayPlaceholderLabel];
    self.placeholder = nil;
}

Вы можете установить заполнитель текста, используя приписанную строку. Передайте цвет, который вы хотите с attributes:

var myTextField = UITextField(frame: CGRect(x: 0, y: 0, width: 200, height: 30))
myTextField.backgroundColor = .blue
myTextField.attributedPlaceholder = NSAttributedString(string: "placeholder text",
                             attributes: [NSForegroundColorAttributeName: UIColor.yellow])

Для Swift 3+ используйте следующее:

myTextField.attributedPlaceholder = NSAttributedString(string: "placeholder text",
                             attributes: [NSAttributedStringKey.foregroundColor: UIColor.white])

Для Swift 4.2 используйте следующее:

myTextField.attributedPlaceholder = NSAttributedString(string: "placeholder text",
                             attributes: [NSAttributedString.Key.foregroundColor: UIColor.white])

Вы можете сделать это быстро, без добавления строки кода, используя Interface Builder.

Выберите UITextField и откройте инспектор удостоверений справа:

Нажмите кнопку «плюс» и добавьте новый атрибут времени выполнения:

placeholderLabel.textColor (Swift 4)

_placeholderLabel.textColor (Swift 3 или меньше)

Используйте Цвет как тип и выберите цвет.

Чтобы установить цвет заполнителя один раз для всех UITextField в вашем приложении, вы можете сделать следующее:

UILabel.appearanceWhenContainedInInstancesOfClasses([UITextField.self]).textColor = UIColor.redColor()

Это позволит установить желаемый цвет для всех заполнителей TextField во всем приложении. Но это доступно только с iOS 9.

}

Если вы установлены из раскадровки.

extension UITextField{
    @IBInspectable var placeHolderColor: UIColor? {
        get {
            return self.placeHolderColor
        }
        set {
            self.attributedPlaceholder = NSAttributedString(string:self.placeholder != nil ? self.placeholder! : "", attributes:[NSAttributedString.Key.foregroundColor : newValue!])
        }
    }
}

В моем случае я сделал следующее:

extension UITextField {
    @IBInspectable var placeHolderColor: UIColor? {
        get {
            if let color = self.attributedPlaceholder?.attribute(.foregroundColor, at: 0, effectiveRange: nil) as? UIColor {
                return color
            }
            return nil
        }
        set (setOptionalColor) {
            if let setColor = setOptionalColor {
                let string = self.placeholder ?? ""
                self.attributedPlaceholder = NSAttributedString(string: string , attributes:[NSAttributedString.Key.foregroundColor: setColor])
            }
        }
    }
}

Я удивлен, увидев, сколько здесь плохих решений.

Вот версия, которая всегда будет работать.

Swift 4.2

extension UITextField{
    @IBInspectable var placeholderColor: UIColor {
        get {
            return self.attributedPlaceholder?.attribute(.foregroundColor, at: 0, effectiveRange: nil) as? UIColor ?? .lightText
        }
        set {
            self.attributedPlaceholder = NSAttributedString(string: self.placeholder ?? "", attributes: [.foregroundColor: newValue])
        }
    }
}

СОВЕТ: Если вы измените текст заполнителя после установки color-, цвет будет сброшен.

Здесь я пишу все UIDesignable из UITextField. С помощью этого кода вы можете напрямую получить к нему доступ из UI файла инспектора в раскадровке

@IBDesignable
class CustomTextField: UITextField {

@IBInspectable var leftImage: UIImage? {
    didSet {
        updateView()
    }
}

@IBInspectable var leftPadding: CGFloat = 0 {
    didSet {
        updateView()
    }
}

@IBInspectable var rightImage: UIImage? {
    didSet {
        updateView()
    }

    }
}

var isRightViewVisible: Bool {
    get {
        return _isRightViewVisible
    }
    set {
        _isRightViewVisible = newValue
        updateView()
    }
}

func updateView() {
    setLeftImage()
    setRightImage()

    // Placeholder text color
    attributedPlaceholder = NSAttributedString(string: placeholder != nil ?  placeholder! : "", attributes:[NSAttributedString.Key.foregroundColor: tintColor])
}

func setLeftImage() {
    leftViewMode = UITextField.ViewMode.always
    var view: UIView

    if let image = leftImage {
        let imageView = UIImageView(frame: CGRect(x: leftPadding, y: 0, width: 20, height: 20))
        imageView.image = image
        // Note: In order for your image to use the tint color, you have to select the image in the Assets.xcassets and change the "Render As" property to "Template Image".
        imageView.tintColor = tintColor

        var width = imageView.frame.width + leftPadding

        if borderStyle == UITextField.BorderStyle.none || borderStyle == UITextField.BorderStyle.line {
            width += 5
        }

        view = UIView(frame: CGRect(x: 0, y: 0, width: width, height: 20))
        view.addSubview(imageView)
    } else {
        view = UIView(frame: CGRect(x: 0, y: 0, width: leftPadding, height: 20))
    }

    leftView = view

        let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
        imageView.image = image
        // Note: In order for your image to use the tint color, you have to select the image in the Assets.xcassets and change the "Render As" property to "Template Image".

    } else {
        view = UIView(frame: CGRect(x: 0, y: 0, width: rightPadding, height: 20))

    rightView = view

Свифт 4:

txtControl.attributedPlaceholder = NSAttributedString(string: "Placeholder String...",attributes: [NSAttributedStringKey.foregroundColor: UIColor.gray])

Álvaro Agüero
31 дек. 2018, в 21:09

Для Swift 4.2 и выше вы можете сделать это, как показано ниже:

textField.attributedPlaceholder = NSAttributedString(string: "Placeholder Text", attributes: [NSAttributedString.Key.foregroundColor: UIColor.white])

Обновление ответа Crubio для Swift 4

Выберите UITextField и откройте инспектор удостоверений справа:

Нажмите кнопку «плюс» и добавьте новый атрибут времени выполнения: placeholderLabel.textColor (вместо _placeholderLabel.textColor)

Используйте Цвет как тип и выберите цвет.

Если вы запустите свой проект, вы увидите изменения.

Это больше о персонализации вашего textField, но в любом случае я поделюсь этим кодом, полученным с другой страницы, и сделал его немного лучше:

import UIKit
extension UITextField {
func setBottomLine(borderColor: UIColor, fontColor: UIColor, placeHolderColor:UIColor, placeHolder: String) {
    self.borderStyle = UITextBorderStyle.none
    self.backgroundColor = UIColor.clear
    let borderLine = UIView()
    let height = 1.0
    borderLine.frame = CGRect(x: 0, y: Double(self.frame.height) - height, width: Double(self.frame.width), height: height)
    self.textColor = fontColor
    borderLine.backgroundColor = borderColor
    self.addSubview(borderLine)
    self.attributedPlaceholder = NSAttributedString(
        string: placeHolder,
        attributes: [NSAttributedStringKey.foregroundColor: placeHolderColor]
    )
  }
}

И вы можете использовать это так:

self.textField.setBottomLine(borderColor: lineColor, fontColor: fontColor, placeHolderColor: placeHolderColor, placeHolder: placeHolder)

Зная, что у вас есть UITextField подключенный к ViewController.

Для Swift

func setPlaceholderColor(textField: UITextField, placeholderText: String) {
    textField.attributedPlaceholder = NSAttributedString(string: placeholderText, attributes: [NSForegroundColorAttributeName: UIColor.pelorBlack])
}

Вы можете использовать это:

self.setPlaceholderColor(textField: self.emailTextField, placeholderText: "E-Mail/Username")

Для чего я решил это, добавив метку поверх ввода и добавив равную ширину, равную высоту и средние ограничения X/Y.

Затем я использовал протокол делегата UITextField, чтобы скрыть/показать эту метку, когда длина текста больше 0 или 0 соответственно. Это может быть выполнено с помощью Editing Changed IBAction из текстового поля.

Это добавляет преимущества гораздо большего количества настроек для вашего заполнителя, чем просто цвет текста. Это также означает, что курсор не будет компенсирован текстом-заполнителем, а затем переместится в начало строки при вводе первого символа, который я сам нахожу раздражающим.

txtField1.attributedPlaceholder = NSAttributedString(string: "-", attributes: [NSAttributedStringKey.foregroundColor: UIColor.white])

Arjun Dobaria

Используйте это для добавления атрибутного заполнителя:

let attributes : [String : Any]  = [ NSForegroundColorAttributeName: UIColor.lightGray,
                                     NSFontAttributeName : UIFont(name: "Helvetica Neue Light Italic", size: 12.0)!
                                   ]
x_textfield.attributedPlaceholder = NSAttributedString(string: "Placeholder Text", attributes:attributes)
