UIWebView webCore在iOS7.1中崩溃（例如：www.latimes.com） [英] UIWebView webCore crashes in iOS7.1 (example: www.latimes.com)

问题描述

在打开洛杉矶时报（www.latimes.com）时，我在iOS应用程序中看到了崩溃。崩溃发生在WebCore的某个地方，我不知道在哪里。使用Zombie或leaks进行性能分析不会返回任何EXE_BAD_ADDRESS错误。

I have being seeing crashes in my iOS app, when opening LA Times (www.latimes.com). The crash happens in WebCore somewhere and I have no clue where. Profiling with both "Zombie" or "leaks" do not return anything for this "EXE_BAD_ADDRESS" error.

我还检查了一个小的，裸露的UIWebView应用程序，我可以重现效果。

I also checked with a small, bare UIWebView app and I could reproduce the effects.

现在，我看到这种情况只发生在洛杉矶时代，但我不确定是否还有其他网站。

Right now, I see this happening only with LA times, but I am not sure if there are other sites as well.

有人可以查看并指导我可能出现此次崩溃的错误/来源吗？

Can someone check on and guide me in what could be the possible error/source for this crash?

编辑：我添加了一个小型UIWebView项目，以
github < a>

I have added a small UIWebView project demonstrating this bug at github

编辑2：该应用程序（包括github上的演示版）在iOS 7.0上完美运行，但在iOS 7.1中崩溃了。 。似乎是iOS 7.1最近的一个错误。我已经向Apple发布了一个错误报告，并会不断更新。
提前致谢，

EDIT 2: The app (include the demo at github) works perfectly fine on iOS 7.0, but crashes in iOS 7.1 ... seems a recent bug with iOS 7.1. I have issued a bug report to Apple and will keep updated. Thanks in advance, Nikhil

推荐答案

我碰巧遇到了同样的问题iOS中的应用程序仅限7.0。

I happened to bump into that same issue with one of my apps in iOS>7.0 only.

这似乎是一个同步问题，可以通过仅从主线程创建webview来解决。

It seems to be a sync issue which can be fixed by creating the webview from the main thread only.

作为修复，我只是在 dispatch_sync（dispatch_get_main_queue（）中包装了我的 UIWebView 创建，^ {...}）;

As a fix I just wrapped my UIWebView creation in a dispatch_sync(dispatch_get_main_queue(), ^{ ... });

它解决了这个问题。
当然如果你的代码在主线程上运行，你不应该这样包装;）

And it solved the problem. Of course if your code is running on the main thread you shouldn't wrap it this way ;)
