Question

我有2个UIWebView控件。使用这两个webview，我已经成功实现了滑动手势动画。

但问题是，当我点击下一个或上一个按钮时（哦，是的，我还有下一个，上一个，第一个和最后一个按钮来读书），滑动效果很好。

但是在webview上它很奇怪。发生以下情况：

滑动不适用于webview。
当我点击下一个或上一个按钮然后滑动webview时，在webview上滑动即可。

以下是我的代码段：

在viewDidLoad中：

  UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeRight:)];
[swipeRight setDirection:UISwipeGestureRecognizerDirectionLeft];
[webViewPage addGestureRecognizer:swipeRight];
[_webview2 addGestureRecognizer:swipeRight];


UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeLeft:)];
[swipeLeft setDirection:UISwipeGestureRecognizerDirectionRight];
[webViewPage addGestureRecognizer:swipeLeft];
[_webview2 addGestureRecognizer:swipeLeft];

在UIWebView上启用滑动：

    -(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
//    NSLog(@"shouldRecognizeSimultaneouslyWithGestureRecognizer");
    return YES;
}



 - (IBAction)btnPrevious_click:(id)sender {
   //some code

}

- (IBAction)btnNext_click:(id)sender {
    //some code
}

我哪里出错？

Answer 1

从您的代码中，您只需添加2个UISwipeGestureRecognizer只有一个UIWebView名称 _webview2 ，请根据您的要求进行更改。

Answer 2

像提到的iPatel一样。每个webview都应该有自己的GestureRecognizers。所以，你应该总共有4个GestureRecognizer。

试试这个： -

UISwipeGestureRecognizer *swipeRight1 = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeRight:)];
[swipeRight1 setDirection:UISwipeGestureRecognizerDirectionLeft];
UISwipeGestureRecognizer *swipeLeft1 = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeLeft:)];
[swipeLeft1 setDirection:UISwipeGestureRecognizerDirectionRight];
[_webview1 addGestureRecognizer:swipeRight1];
[_webview1 addGestureRecognizer:swipeLeft1];   

UISwipeGestureRecognizer *swipeRight2 = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeRight:)];
[swipeRight2 setDirection:UISwipeGestureRecognizerDirectionLeft];
UISwipeGestureRecognizer *swipeLeft2 = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeLeft:)];
[swipeLeft2 setDirection:UISwipeGestureRecognizerDirectionRight];
[_webview2 addGestureRecognizer:swipeRight2];
[_webview2 addGestureRecognizer:swipeLeft2];
