Using HTML and Local Images Within UIWebView

Stop UIWebView from “bouncing” vertically?

by

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.

UIWebView open links in Safari
