iOS: webview swipe gesture - ios

Question

I have 2UIWebView controls. Using these 2 webviews, I have successfully implemented swipe gesture animation.
But the problem is, when I click on next or previous button(oh yes, I also have next, previous, first and last buttons to read a book), swipe works perfectly.
But on webview it works weirdly. Following happens:
Swipe doesn't work on webview.
When I click on next or previous buttons and then swipe the webview, swipe on webview works.
Following is my code snippet:
In viewDidLoad:
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];
To enable swipe on UIWebView:
-(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
}
Where am I getting wrong?

Answer 1

From your code, you have to added 2 UISwipeGestureRecognizer in only one UIWebView name is _webview2 please change it as per your requirement.

Answer 2

Like iPatel mentioned. Each of the webview should has its own GestureRecognizers. So, you should have 4 GestureRecognizers in total.
Try this:-
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];
