Turn off scrolling (bounces) in UIWebView?

One line is all it took for me. I put it in my viewDidLoad in my ViewController class. I tried the javascript but it only worked on certain pages. also, any page with embedded div content or iframes or dynamic javascript was preventing the javascript fix from working.


[[[myWebLabel subviews] lastObject] setScrollEnabled:NO];

Hi everyone,

read this thread, because I had the same problems with the UIWebView.

Since some approaches posted here did not work out for me, I took another (closer) look at the API.

YES, UIWebView does not inherit from UIScrollView.

BUT! It does conform to the UIScrollViewDelegate

Which means, you can inherit UIWebView and override
- (void)scrollViewWillBeginDragging: (UIScrollView *)scrollView

in this way:

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView{

	scrollView.scrollEnabled = NO;
}

That's it. No "subviews last index" and so on...

Worked pretty fine for me and I doubt that it will be rejected by Apple.

Rock on!

Hey,

anybody try

[(UIScrollView *) [webView6.subviews objectAtIndex:0] setAlwaysBounceVertical:NO];

worked for me

Worked great.
Seems UIScrollView is first subview of UIWebView.






oooooooops !!!!!!! :-) krashing on below iPhone 4.1 OS.. any other way

Implementing the delegate Method worked in 95% for me,

since the WebView did scroll some pixels and did top then...

here is my updated solution:

- (id) initWithFrame:(CGRect)frame{
	
	if (self = [super initWithFrame:frame]) {
		
		for (unsigned i = 0; i < [[self subviews] count]; i++) {
			
			if ([[[self subviews] objectAtIndex:i] class] == [UIScrollView class]) {
				
				UIScrollView *scrollView = (UIScrollView*) [[self subviews] objectAtIndex:i];
				
				[scrollView setScrollEnabled:NO];
			}
		}
	}
		
	return self;
}

Subclassing WebView and then loop through all subViews, if it is a ScrollView, disable it. So I don't mind on which position of the subview array the scrollView is.

Why do all these sub classing and hacks? Put this function in your interface and call it:

-(void)disableScrollingOnWebView:(UIWebView*)webView
{
	for(id sub in [webView subviews]
	{
		if([sub isKindOfClass:[UIScrollView class]]
		{
			[sub setScrollEnabled:NO];
		}
	}
}

i.e.

[self disableScrollingOnWebView:myWebView];

that is the same thing posted by TieAetsch....

yes, he used it in init, but the idea was the same

Thanks, the javascript does indeed work and prevents scrolling up/down completely. Unfortunately for the work I'm doing, I do need it to scroll but not bounce (or show the grey-ish top/bottom bounce indicator bars). I'll need to find a different solution than the javascript.

-(void)disableBouncesOnWebView:(UIWebView*)webView
{
	for(id sub in [webView subviews])
        {
            if([sub isKindOfClass:[UIScrollView class]])
               {
                   UIScrollView *scrollView = (UIScrollView*)sub;
                   [scrollView setBounces:NO];
               }
        }
}

You could get really crazy and do this,

[webView setUserInteractionEnabled:NO];

that is not what we want to achieve....
