I'm基本上使用在一个UIViewController，已推到NavigationController去取JSON它显示其内容的AFJSONRequestOperation。 难道AFNetworking导致崩溃（在线程5）that's？ 或可能是在我的代码中的缺陷？ I'm很坚持，并经常发生。 任何帮助或问题，非常感谢！

Answer 1:

它不是用螺纹5根据崩溃的问题; 它是在线程0的一个问题。

布赖恩在他的博客中添加了计时器WebKit中是如何运作的一些背景信息。

http://brrian.tumblr.com/post/13951629341/how-webkits-event-model-works

它有趣的是，这个问题的操作系统是6.0.1，而不是更新的6.1版，也不是7.x版（截至撰写本文时）。

一个CFRelease期间崩溃发生，而这往往已经被释放的资源被释放时发生。 我的建议是，看看这个问题上的任何新的操作系统发生，因为它听起来像一个WebKit的错误。 WebKit是负责计时的代码。

计时器代码已被无论如何再加工： https://trac.webkit.org/changeset/143210

所以，我认为最好的办法是看，看最新的iOS曾经有这样的碰撞，或者最新的6.x的（6.1）。

如果做不到这一点，假设你无法重现的问题，因为你有网络查询（和DB查询）怎么回事，经典的方式计时器进入画面是，当你有慢/不可靠的网络连接。 使用苹果公司的网络链接调理模拟这样的条件。 这可能显示在WebKit的问题。



Answer 2:

检查一些广告打开iTunes中。 也许你在你的应用程序的初始化开太多线程。 你可以尝试排队这些请求。 只是随机的想法..
