Ipad 如何在滚动时停止缩放图像的边界？

这是我使用scrollview拖动缩放图像的编码。在缩放时图像移动速度很快。任何人都有办法克服这个问题

 UIScrollView1.contentSize=CGSizeMake(UIImageView1.frame.size.width, UIImageView1.frame.size.height);
 UIScrollView1.maximumZoomScale = 10.0;
 UIScrollView1.minimumZoomScale = 1.0;
 UIScrollView1.clipsToBounds = YES;
 UIScrollView1.userInteractionEnabled = YES;
 UIScrollView1.scrollEnabled = YES;
 UIScrollView1.pagingEnabled=YES;

 UIScrollView1.directionalLockEnabled = YES;
 UIScrollView1.delegate = self;
 [UIScrollView1 addSubview:UIImageView1];
 [self.view addSubview:UIScrollView1];

你能详细说明一下“在缩放时间时图像移动得很快”吗？

Thanks,
