Swipe gesture for back/forward in UIWebView

웹뷰에서 Swipe 재스쳐를 통해 웹의 back / forward를 구현해야 할 일이 있어서 아래의 소스를 찾았다.

UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];

UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];

// Setting the swipe direction.

[swipeLeft setDirection:UISwipeGestureRecognizerDirectionLeft];

[swipeRight setDirection:UISwipeGestureRecognizerDirectionRight];

// Adding the swipe gesture on WebView

[webView addGestureRecognizer:swipeLeft];

[webView addGestureRecognizer:swipeRight];

- (void)handleSwipe:(UISwipeGestureRecognizer *)swipe {

    if (swipe.direction == UISwipeGestureRecognizerDirectionLeft) {

        // 왼쪽으로 Swipe되었을 때 처리

    }

    if (swipe.direction == UISwipeGestureRecognizerDirectionRight) {

        // 오른쪽으로 Swipe되었을 때 처리   

    } 

}
