Question

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

Answer 1

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])

Click on the + button and add a new runtime attribute: _placeholderLabel.textColor

Run your app.

在 swift 中，您可以使用代码更改占位符颜色，

 name_textField .setValue(UIColor.redColor(), forKeyPath: "_placeholderLabel.textColor")

Answer 4

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()])
} }
