Action when the small cross button of UITextField is pressed

Question

I can add a small cross button that is used to clear all the text in a single click in a UITextField with the following code.

textField.clearBut         


        

Answer 1

Use the delegate method textViewShouldClear::

Asks the delegate if the text field’s current contents should be removed.

- (BOOL)textFieldShouldClear:(UITextField *)textField

Parameters

textField

The text field containing the text.

Return Value

YES if the text field’s contents should be cleared; otherwise, NO.

Discussion

The text field calls this method in response to the user pressing the built-in clear button. (This button is not shown by default but can be enabled by changing the value in the clearButtonMode property of the text field.) This method is also called when editing begins and the clearsOnBeginEditing property of the text field is set to YES.

Implementation of this method by the delegate is optional. If it is not present, the text is cleared as if this method had returned YES. Availability

* Available in iOS 2.0 and later.

Answer 2
