推荐答案
我是exp在iOS 8上遇到同样的问题，更具体地说，iPad 3比其他人更容易失败。
I'm experiencing the same issue on iOS 8 and more specifically an iPad 3 fails much more often than others.
根据您的帖子以及其他几个我能找到的帖子，似乎这只是iOS8上的 UIWebView 的问题，因为它适用于iOS7。
Based on your post and a couple of others that I was able to find, it seems that it's an issue with UIWebView on iOS8 only, as it works on iOS7.
我是什么已完成的是在iOS8上使用新的 WKWebView ，这不会出现同样的问题，同时继续使用 UIWebView 在iOS7上。
What I've done is to use the new WKWebView on iOS8, which doesn't present the same issue, while continuing to use UIWebView on iOS7.
最好的办法是用Apple提交雷达并切换到 WKWebView in与此同时。
The best thing to do would be to file a radar with Apple and switch to WKWebView in the meantime.
