Editing Changed IB event fires before text is changed in a UITextField

I am firing the updateFindName method by linking it to the Editin开发者_运维问答g Changed event in IB. The problem is that the method seems to fire before recording the actual change in the UITextField uiFindName. I wanted to update the uiFindNameLabel's text to uiFindName's placeholder text when the user clears all text in uiFindName, and it does, but only AFTER another character is typed into the uiFindName. Any tips?

- (IBAction)updateFindName:(id)sender {
    if ([uiFindNameLabel.text isNotEmpty]) {
        uiFindNameLabel.text = uiFindName.text;
    } else {
        uiFindNameLabel.text = uiFindName.placeholder;
    }
}

Note, isNotEmpty is just a method checking for empty strings.

You could use the UITextField's delegate method – textField:shouldChangeCharactersInRange:replacementString:.

There you can determine exactly what the text before and after the entered character should be.
