detect Swipe gesture in UIWebview
ipad, iphone, touchesmoved, uigesturerecognizer, uiwebview
Solution
Just attach UIGestureRecognizer subclass to that view and hold on for calls...
UISwipeGestureRecognizer* rightSwipeRecognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(someAction)];
rightSwipeRecognizer.numberOfTouchesRequired = 2;
rightSwipeRecognizer.direction = UISwipeGestureRecognizerDirectionRight;
rightSwipeRecognizer.cancelsTouchesInView = YES;
[self.webView addGestureRecognizer:rightSwipeRecognizer]; // add in your webviewrightSwipeRecognizer
Problem
I am new to `iPhone` developer, I made epub reader and loaded each page of epub in my `webview` What i want to is, when user does `right swipe gesture` 2nd time then i want to navigate to new page, i do not want to do anything when user does `right swipe gesture` for first time. `UISwipeGestureRecognizer *swipeRight` Is there any method something like, ``` if(swipeRight.touch.count > 2) { // do this } ``` Any help will be appriciated. Thanks In Advance ! EDIT ``` -(void)scrollViewDidScroll:(UIScrollView *)scrollView{ float scrollViewHeight = scrollView.frame.size.height; float scrollContentSizeHeight = scrollView.contentSize.height; float scrollOffset = scrollView.contentOffset.y; if (scrollOffset == 0) { swipeUp = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeLeftAction:)]; swipeUp.direction = UISwipeGestureRecognizerDirectionUp; swipeUp.numberOfTouchesRequired=2; swipeUp.delegate = (id<UIGestureRecognizerDelegate>)self; swipeUp.cancelsTouchesInView=YES; [_webview addGestureRecognizer:swipeUp]; } else if (scrollOffset + scrollViewHeight == scrollContentSizeHeight) { swipeDown = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeRightAction:)]; swipeDown.direction = UISwipeGestureRecognizerDirectionDown; swipeDown.numberOfTouchesRequired=2; swipeDown.delegate = (id<UIGestureRecognizerDelegate>)self; swipeDown.cancelsTouchesInView=YES; [_webview addGestureRecognizer:swipeDown]; } ```
