• (void)touchDown:(UIButton *)sender { [_textField resignFirstResponder];

  if (sender == _increaseBtn) { [self cleanTimer]; _timer = [NSTimer scheduledTimerWithTimeInterval:_longPressSpaceTime target:self selector:@selector(increase) userInfo:nil repeats:YES]; } else { [self cleanTimer]; _timer = [NSTimer scheduledTimerWithTimeInterval:_longPressSpaceTime target:self selector:@selector(decrease) userInfo:nil repeats:YES]; } [_timer fire]; } 可以在timer之前先失效一下
