如何阻止 UIScrollView 水平彈跳?
推薦答案
for (id subview in webView.subviews)
if ([[subview class] isSubclassOfClass: [UIScrollView class]])
((UIScrollView *)subview).bounces = NO;

App Store 也會(huì)接受它.

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;
WKWebView 也是如此.
