I got the code below from [this](https://stackoverflow.com/questions/1247113/iphone-keyboard-covers-uitextfield) SO question. I'm trying to slide up textfields when I begin editing (because they otherwise get covered by the iPhone keyboard). However, the log statement reveals that the textFieldDidBeginEditing method is not getting called. 

I have the code below in two different subclasses of UIViewController. In one of them, for example, I have a textfield connected from the storyboard to the UIViewController like this

```
@property (strong, nonatomic) IBOutlet UITextField *mnemonicField;

```

I moved the textfield up to the top of the view (i.e. not covered by keyboard) so that I could edit it to try to trigger the log statement but it didn't work. The text field otherwise works as expected i.e. the data I enter is getting saved to coreData etc etc. 

Can you explain what I might be doing wrong?

```
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
    NSLog(@"The did begin edit method was called");
    [self animateTextField: textField up: YES];
}

- (void)textFieldDidEndEditing:(UITextField *)textField
{
    [self animateTextField: textField up: NO];
}

- (void) animateTextField: (UITextField*) textField up: (BOOL) up
{
    const int movementDistance = 180; // tweak as needed
    const float movementDuration = 0.3f; // tweak as needed

    int movement = (up ? -movementDistance : movementDistance);

    [UIView beginAnimations: @"anim" context: nil];
    [UIView setAnimationBeginsFromCurrentState: YES];
    [UIView setAnimationDuration: movementDuration];
    self.view.frame = CGRectOffset(self.view.frame, 0, movement);
    [UIView commitAnimations];
}

```
