Discussion of [UITextField clearButtonRectForBounds]
You should not call this method directly. If you want to place the clear button in a different location, you can override this method and return the new rectangle. Your method should call the super implementation and modify the returned rectangle’s origin only. Changing the size of the clear button may cause unnecessary distortion of the button image.
