For TextView you can use...

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
- (void)textViewDidChange:(UITextView *)textView

For TextField you can use...

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string

See UITextViewDelegate and UITextFieldDelegate on Apple website.
