title: How to call method on UITextField after editing in iOS
body: <p>I have a UITextField on which I'm calling the animation code below. It runs fine but this code runs when I press the return key. I want this code to automatically run after the user enters any data in the text field without pressing the return key.</p>
  
  <pre><code>    - (BOOL)textFieldShouldReturn:(UITextField *)textField
         {
           [patientNameTextField resignFirstResponder];
  [addressTextField resignFirstResponder];
           [doctortTextField resignFirstResponder];
       [self showAnimationBack];
           return YES;
      }
  </code></pre>
