Stop UIWebView from "bouncing" vertically?

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.

Brad's method worked for me. If you use it you might want to make it a little safer.

id scrollView = [yourWebView.subviews objectAtIndex:0];
if( [scrollView respondsToSelector:@selector(setAllowsRubberBanding:)] )
{
    [scrollView performSelector:@selector(setAllowsRubberBanding:) withObject:NO];
}

If apple changes something then the bounce will come back - but at least your app won't crash.

I traversed the collection of UIWebView's subviews and set their backgrounds to [UIColor blackColor], the same color as the webpage background. The view will still bounce but it will not show that ugly dark grey background.

Here's two newer potential solutions. Apparently, you can use jqtouch or pastrykit to disable scrolling. However, I haven't got these to work. You might be more competent.

This link helped me lot.....Its easy.. There is a demo..

One of the subviews of UIWebView should be a UIScrollView. Set its scrollEnabled property to NO and the web view will have scrolling disabled entirely.

Note: this is technically using a private API and thus your app could be rejected or crash in future OS releases. Use @try and respondsToSelector

Look into the bounces property of UIScrollView. Quoth the Apple docs:

If the value of the property is YES (the default), the scroll view bounces when it encounters a boundary of the content. Bouncing visually indicates that scrolling has reached an edge of the content. If the value is NO, scrolling stops immediately at the content boundary without bouncing.

Make sure you're using the right UIScrollView. I'm not sure what the hierarchy looks like for a UIWebView, but the scroll view could be a parent, not a child, of the UIWebView.
