iOS UIwebview缩放比例检测

我有一个

UIWebview

，其中我有

左右滑动

的手势来移动到

UIWebview

中的下一页。当

webview

被缩放时，我不想允许滑动手势。我在

ViewdidLoad

中完成了此操作

webView = [[UIWebView alloc]initWithFrame:self.view.bounds];
webView.frame = CGRectMake(30, 106,966,500);
webView.scrollView.bounces = NO;
webView.scrollView.delegate = self;
webView.scalesPageToFit = YES;
[self.view addSubview:webView];

我还在ViewdidLoad中添加了手势：

//Swipe Gesture for Webview
    swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeRightAction)];
    swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeLeftAction)];

    swipeRight.direction = UISwipeGestureRecognizerDirectionRight;
    swipeRight.delegate = self;
    [webView addGestureRecognizer:swipeRight];

    swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft;
    swipeLeft.delegate = self;
    [webView addGestureRecognizer:swipeLeft];

---

完成缩放后，不应出现该手势。如何解决此问题？

如果完成缩放，请设置“[webView RemovegestureRecognitor:swipeLeft]；”和“[webView RemovegestureRecognitor:swipeRight]；”我怎样才能检测到变焦被完成..请参考此感谢Ashini和Spynet。。
