Customizing the appearance of UITextField placeholder text can enhance the user experience of your iOS application. In this guide, we will cover how to change the placeholder text color in UITextField using various methods, ensuring compatibility with different iOS versions.
Using Attributed Strings
Since iOS 6, UITextField supports attributed strings, allowing you to easily change the placeholder text color. Here’s a straightforward method:
if ([textField respondsToSelector:@selector(setAttributedPlaceholder:)]) {
UIColor *color = [UIColor blackColor];
textField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:@"Placeholder Text" 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.
}Alternative Methods
Depending on your project requirements and iOS version compatibility, you may consider the following alternative methods:
Using Swift
For Swift developers, here’s how you can achieve the same result:
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])Swift 4.2 and Above
myTextField.attributedPlaceholder = NSAttributedString(string: "Placeholder Text", attributes: [NSAttributedString.Key.foregroundColor: UIColor.red])Using Objective-C
If you are working with Objective-C, here is a method to change the placeholder text color:
UIColor *color = [UIColor lightTextColor];
YOURTEXTFIELD.attributedPlaceholder = [[NSAttributedString alloc] initWithString:@"PlaceHolder Text" attributes:@{NSForegroundColorAttributeName: color}];Storyboard Approach
For those who prefer setting attributes directly in Storyboard, you can create an extension:
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)
}
}
}Conclusion
Changing the placeholder text color in a UITextField is a relatively simple task that can significantly improve the visual appeal of your app. Depending on your development environment and target iOS version, you can choose the method that best fits your needs.
