一张图 高度小于屏幕高度的图 放大之后 ，左右滑动，很容易切换到下一张图上，有没有什么办法可以优化 about knphotobrowser HOT 1 OPEN

`// delegate of gesture to let scrollView can scroll or not

• (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {
  if([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {
  UIPanGestureRecognizer *pan = (UIPanGestureRecognizer *)gestureRecognizer;
  CGPoint po = [pan velocityInView:pan.view];

    if (po.y > 0 && _scrollView.contentOffset.y <= 0) {
        
        //优化
        if (_scrollView.contentSize.width > __gScreenWidth) {
            
            NSLog(@"😭😭😭😭😭😭😭😭😭😭😭😭😭😭 ");
            _scrollView.scrollEnabled = true;
            return false;
        }
        
        
        //下面是 原逻辑
        _scrollView.scrollEnabled = false;
        return true;
    }else {
        _scrollView.scrollEnabled = true;
        return false;
    }
  

  }
  return false;
  }`
