Ios [NSAutoreleasePool drain]时NSURLConnection崩溃

嗨，我有一份事故报告如下。我看到了许多关于NSURLConnectionInternal崩溃的答案，但我没有看到与-[NSAutoreleasePool drain]相关的答案。我真的不知道为什么会发生这样的事。真的是连接崩溃了吗

释放某些对象时出现问题，可能是过度释放。你可以打开僵尸，看看它是否是由过度释放引起的，如果是，是什么对象的。这是crashlytics的用户崩溃日志，我无法打开僵尸你不能复制它吗？我想您必须仔细查看您的代码。它看起来像是某个自动释放的数组的成员。数组可能在作为连接委托提供的委托方法中自动释放。你在用ARC吗？也许你可以试着分析一下，看看有没有什么问题？
