这是由我或UIKit本身引起的崩溃吗？

Question

这个崩溃报告对我来说真的很难处理。我偶尔会看到它，而且它不可能修复，因为它并不真正给我提供我的代码的任何参考。

这是由苹果引起的崩溃，我不必担心它吗？

Answer 1

这不是由苹果引起的。下面是坠毁的入口点。确保一些相关的对象/视图不会被取消分配。

MyApp 0x0003f7b5 +[AFURLConnectionOperation networkRequestThreadEntryPoint:] (AFURLConnectionOperation.m:161 

更新：

我收回我的对象​​释放语句。我怀疑这个崩溃可能发生，因为UI元素在后台线程中被创建\更新。我的意思是在网络回调方法中创建/更新的UI元素。

该问题的解决方案是在main_queue中添加dispatch_async以执行UI更新。
