Swipe gesture for back/forward in UIWebView?

I have a WebView in my app.

Because it is a tabbed application I'm not able to add buttons for going back/forward on the website.

I want to go back/forward by swiping. Right swipe from the left side/edge is back… like in Safari browser for iOS.

How can I do it? I think i should use "Screen Edge Pan Gesture Recognizer", right?

Solution

  • Why not just use a swipe gesture recognizer?

    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) {
    NSLog(@"Left Swipe");
}

if (swipe.direction == UISwipeGestureRecognizerDirectionRight) {
    NSLog(@"Right Swipe");   
} 

}
