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
.
