Trigger textFieldShouldClear programmatically

If I understand correctly, the UITextFieldDelegate method textFieldShouldClear gets triggered once the user taps on the clear button/icon provided with and enabled for a UITextField. But I need to clear the UITextField programmatically, which, in the absence of a clear method for UITextField (that I could find), I am doing like so:

textField.text = @"";

The above, however, does not trigger the textFieldShouldClear delegate method that I need. Any ideas how I could do it?

Alternatively, does my call above trigger any other delegate method? I checked, and textInputChanged is not called in this case.

I ended up subclassing UITextField and implementing the following method:

- (void)setText:(NSString *)text {

    [super setText:text];

    [self textInputChanged:nil];
}

Where textInputChanged: is the UITextFieldDelegate method that I needed to get called whenever text is set programmatically.

TextField delegate methods will not fire if you set the text programmatically.

You can probably just perform whatever logic needs to be done after your textField.text = @""; line though, right?
