如何阻止UIScrollView水平弹跳？

推荐答案

for (id subview in webView.subviews)
  if ([[subview class] isSubclassOfClass: [UIScrollView class]])
    ((UIScrollView *)subview).bounces = NO;

更新：在iOS 5.x +中有一种更简单的方法 - UIWebView 有 scrollView 属性，因此您的代码可能如下所示：

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;
