Answer 2

When You set the button title, if do not want the effect, you can set the titleLable.text first.

Try this:

- (void)respondsToTextField:(UITextField *)sender {

    if ([sender.text isEqualToString:@""]) {

        _cancleOrConfirmButton.titleLabel.text = @"Cancel";
        [_cancleOrConfirmButton setTitle:@"Cancel" forState:UIControlStateNormal];

    }else {

        _cancleOrConfirmButton.titleLabel.text = @"Search";
        [_cancleOrConfirmButton setTitle:@"Search" forState:UIControlStateNormal];

    }

}
