阻止 UIWebView “弹跳"；垂直?

有谁知道如何阻止 UIWebView 垂直弹跳?我的意思是当用户触摸他们的 iPhone 屏幕，向下拖动手指时，webview 会在我加载的网页上方显示一个空白点?

Does anyone know how to stop a UIWebView from bouncing vertically? I mean when a user touches their iphone screen, drags their finger downwards, and the webview shows a blank spot above the web page I had loaded?

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;

...似乎工作正常.

App Store 也会接受它.

It'll be accepted to App Store as well.

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

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;

WKWebView 也是如此.
