我遇到多次崩溃,原来的iOS方法似乎是从第三方库调用函数。这是一个例子:
Thread: Unknown Name (Crashed)

12 CoreFoundation 0x37d2ed49 CFRunLoopRunInMode + 105 + 104
13 GraphicsServices 0x358e22eb GSEventRunModal + 75 + 74
14 UIKit 0x3a1b42f9 UIApplicationMain + 1121 + 1120
15 FireChat 0x43b3 main (main.m:8)
对我而言,似乎[NSDictionary valueForKey:]
方法正在调用来自第三方库的[OTOverlayButton drawRect:]
。这应该是不可能的 - 我是否错误地阅读了崩溃报告?
[OTOverlayButton drawRect:]
。请注意,该字典包含(my)对象,其中包含指向第三方库中对象的指针。
图书馆供应商和我都感到困惑。
感谢。

我认为这次崩溃的原因是在返回结构的方法上调用performSelector:
导致的内存损坏。有关更多详细信息,请参阅此博客文章:
