My requirement is such that when placeholder of textfield is visible then its color should be gray and font size 10, but when user starts typing into the textfield, its color should be black and font size 14. I have tried this:
textField.attributedPlaceholder = NSAttributedString(string: placeholderText,
attributes: [NSAttributedString.Key.foregroundColor: Color.iPhoneGrayColor, NSAttributedString.Key.font: UIFont(name: "SourceSansPro-Regular", size: 10)!])
textField.textColor = UIColor.black
textField.font = UIFont(name: "SourceSansPro-Regular", size: 14)!
But, my placeholder font size is getting overridden by textfield.font, so I am unable to get placeholder of size 10. Where am I going wrong? Tried this for couple of hours now. Any help will be appreciated.
Simply set the placeholder after setting the font since setting the font also applies to the placeholder (see https://developer.apple.com/documentation/uikit/uitextfield/1619604-font):
textField.font = ...
textField.textColor = ...
textField.attributedPlaceholder = ...
Try this code into your viewDidLoad() method:
textField.attributedPlaceholder = NSAttributedString(string: placeholderText, attributes: [NSAttributedString.Key.foregroundColor: Color.iPhoneGrayColor, NSAttributedString.Key.font: UIFont(name: "SourceSansPro-Regular", size: 10)!])
textField.textColor = UIColor.black
textField.font = UIFont(name: "SourceSansPro-Regular", size: 14)!
Just try this code, take the UITextFieldEditingChanged action outlet and use as below.
@IBAction func nameTextFieldEditingChanged(_ sender: UITextField) {
if sender.text?.isEmpty ?? true {
//placeholder text size set here
textField.font = UIFont(name: "SourceSansPro-Regular", size: 10)!
} else {
// When user starting typing
textField.textColor = UIColor.black
textField.font = UIFont(name: "SourceSansPro-Regular", size: 14)!
}
}
If any doubt please comment ].
