how can I call a method as I click UITextField?

Question

I want to ask that how can I call a method as I do click(touch for start writing) in iphone UITextField, as like we click UIButton and put method in "addTarget", is there any way for UITextFields ?

Answer 1

implement a UITextFieldDelegate and do whatever you want to do in - (BOOL)textFieldShouldBeginEditing:(UITextField *)textField or - (void)textFieldDidBeginEditing:(UITextField *)textField

You should use the first method if you want to stop the textfield from behaving like a textfield. For example if you want to open the textfield editor in a modal view. You can return NO there if you don't want this behavior.

Edit: Here is the code to call myMethod:

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField { 
    [self myMethod]; 
    return YES; 
}

Answer 2

You can set textField's delegate and implement textFieldShouldBeginEditing: method in it - that method will get called when user taps the field and before it goes into editing.

See UITextFieldDelegate reference for more methods available.
