You can catch that key in
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)stringIt is not written explicitly in the docs but if you press the backspace key then the last parameter
stringwill have a length of 0.At least this worked for me when using UITextView objects.
Hope this helps 🙂
