/// 点击: 单击逐次加减,长按连续快速加减

• (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
