Question

在线查看崩溃报告，这似乎是主要问题。

知道它指的是什么？（图形太多，图形太重等等。）

奇怪的是，我没有在模拟器或设备上发生任何崩溃。

Answer 1

由于__NSThreadPerformPerform故意抛出异常，因此传递给它的信息有问题。由于异常代码为零，因此可能存在指向某事的零指针。

这些方法中的一种（或类似方法）可能在信息不良时调用，或者信息在实际运行时是坏的。

performSelectorOnMainThread:withObject:waitUntilDone: 
performSelectorInBackground:withObject: 
performSelector:withObject:afterDelay:

另外，另一篇StackOverflow文章具有几乎相同的堆栈，而且其中一篇文章是由损坏的通讯簿条目引起的。（iPhone crash that only happens on one phone）
