的iOS：網頁視圖掃掠姿態

Question

我有2個UIWebView控件。使用這2個網頁瀏覽，我已成功實施滑動手勢動畫。

但問題是，當我點擊下一個或前一個按鈕（哦，是的，我也有一個，前，第一和最後一個按鈕來讀一本書），刷卡完美的作品。

但上的WebView它工作古怪。出現以下情況：

• 刷卡不上的WebView工作。
• 當我一個或下一個按鈕，按一下，然後輕掃的WebView上的WebView刷卡有效。

以下是我的代碼片段：

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]; 

要在UIWebView的啓用刷卡：

-(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 
} 

當我收到錯了嗎？

Answer 1

從你的代碼，你必須添加2 UISwipeGestureRecognizer只在一個UIWebView名字是_webview2請更換按您的要求。

Answer 2

像iPatel提及。每個webview都應該有自己的GestureRecognizers。所以，你應該總共有4個GestureRecognizers。

試試這個： -

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];
