Stop UIWebView from "bouncing" vertically?

Question

for (id subview in webView.subviews)
  if ([[subview class] isSubclassOfClass: [UIScrollView class]])
    ((UIScrollView *)subview).bounces = NO;

...seems to work fine.

It'll be accepted to App Store as well.

Update: in iOS 5.x+ there's an easier way - UIWebView has scrollView property, so your code can look like this:

webView.scrollView.bounces = NO;

Same goes for WKWebView.

I was looking at a project that makes it easy to create web apps as full fledged installable applications on the iPhone called QuickConnect, and found a solution that works, if you don't want your screen to be scrollable at all, which in my case I didn't.

In the above mentioned project/blog post, they mention a javascript function you can add to turn off the bouncing, which essentially boils down to this:

    document.ontouchmove = function(event){
        event.preventDefault();
    }

If you want to see more about how they implement it, simply download QuickConnect and check it out.... But basically all it does is call that javascript on page load... I tried just putting it in the head of my document, and it seems to work fine.

Well all I did to accomplish this is :

UIView *firstView = [webView.subviews firstObject];

if ([firstView isKindOfClass:[UIScrollView class]]) {

    UIScrollView *scroll = (UIScrollView*)firstView;
   [scroll setScrollEnabled:NO];  //to stop scrolling completely
   [scroll setBounces:NO]; //to stop bouncing 

}

Works fine for me... Also, the ticked answer for this question is one that Apple will reject if you use it in your iphone app.

In the iOS 5 SDK you can access the scroll view associated with a web view directly rather than iterating through its subviews.

So to disable 'bouncing' in the scroll view you can use:

myWebView.scrollView.bounces = NO;

See the UIWebView Class Reference.

(However if you need to support versions of the SDK before 5.0, you should follow Mirek Rusin's advice.)
