Custom UITextField clear button

7 Solutions Collect From Internet About “Custom UITextField clear button”

You can set your own custom clear button to the text field’s rightView property. Make sure set the rightViewMode property to UITextFieldViewModeWhileEditing or UITextFieldViewModeAlways, whatever makes sense for your case.

If the button’s position isn’t right for your need, you can subclass UITextField and override the rightViewRectForBounds: method.

The documentation says the default for the clearButtonMode property is UITextFieldViewModeNever, but I suspect Interface Builder may set it to UITextFieldViewModeWhileEditing – Make sure you set it to the “never” value so it doesn’t appear.

All these properties are documented in UITextField Class Reference.

You can access that property using KVO:

UIButton *clearButton = [myTextField valueForKey:@"_clearButton"];
[clearButton setImage:[UIImage new] forState:UIControlStateNormal];

Tested iOS7.0 – 8.4

It is possible to update the backgroundImage of all clear buttons using the following UIAppearance method. Unfortunately you cannot update the image of the button:

UIButton *defaultClearButton = [UIButton appearanceWhenContainedIn:[UITextField class], nil];
[defaultClearButton setBackgroundImage:[UIImage imageNamed:@"clearButtonBkg1.png"] forState:UIControlStateNormal];

Using the following images, this results in the following clear button:

White background image @3x:

White clear button background

Note: This will update the background image of ALL buttons contained in textfields

Swift 2.2+ / iOS 9+ version of @Brody Robertson’s answer:

let defaultClearButton = UIButton.appearanceWhenContainedInInstancesOfClasses([UITextField.self])
defaultClearButton.setBackgroundImage(UIImage(named: "ClearIcon"), forState: UIControlState.Normal)

One approach would be to create a custom UITextField that has your desired image as a subview and clears the parent text field when tapped. You disable the default button and add your custom behavior in this custom text field.

This should get you started. If there are any more concrete questions, feel free to edit your question or comment here if it’s a minor problem.

Swift 3.0

myTextField.clearButtonMode = .whileEditing
if let clearButton = myTextField.value(forKeyPath: "_clearButton") as? UIButton {
    clearButton.setImage(UIImage(named:"myImage"), for: .normal)
    clearButton.setImage(UIImage(named:"myImage"), for: .highlighted)

But really use it carefully. If Apple change implementations in future iOS releases, it would not be work

Swift 3

let customClearButton = UIButton.appearance(whenContainedInInstancesOf: [UITextField.self])
customClearButton.setBackgroundImage(UIImage(named: "custom_cb"), for: .normal)
