Summary:

A UITextField that appears inside of a UIAlertView doesn't correctly respond to several delegate methods. A UITextField in a regular UIView behaves correctly.

Steps to Reproduce:

1. Instantiate an instance of UIAlertView.
2. Set the alertViewStyle property of the alert view to UIAlertViewStyleSecureTextInput or UIAlertViewStylePlainTextInput. (I haven't tested UIAlertViewStyleLoginAndPasswordInput thoroughly.)
3. Set the delegate on the the text field using something like this: [[alert textFieldAtIndex:0] setDelegate:self];
4. Implement textFieldShouldReturn: and textField:shouldChangeCharactersInRange:replacementString:
5. Run the app and invoke the alert view.
6. Tap the return key.

Expected Results:

The app should call textFieldShouldReturn:

Actual Results:

textField:shouldChangeCharactersInRange:replacementString: is called.

Regression:

This behaved correctly on iOS 6.

Notes:

textField:shouldChangeCharactersInRange:replacementString: is called instead of the other delegate methods. I used textFieldShouldReturn: as an example because it was the delegate method which I was initially trying to call, alerting me to the bug. (If you'll excuse the pun.)
