_CFAutoreleasePoolPop崩溃 [英] Crash at _CFAutoreleasePoolPop

问题描述

我从Fabric崩溃，堆栈在下面:

I got a crash from Fabric,the stack is below:

我不知道为什么(anonymous namespace)::AutoreleasePoolPage::pop(void*)之后会是_Block_release.是否有可能在autoreleasepool中添加了一个块?如果可能，为什么该块在发布时崩溃而在调用时没有崩溃?

I don't know why it would be _Block_release after (anonymous namespace)::AutoreleasePoolPage::pop(void*). Is it possible that a block was added to autoreleasepool?if possible, why the block crashed at release and it not crashed at invoke?

推荐答案

好，我已经解决了这个错误.崩溃的原因是我为NSMutableArray钩上了objectAtIndex函数.如果用户从后台切换，该应用程序将崩溃-[UIKeyboardLayoutStar release]: message sent to deallocated.

Ok，I had resolve this bug.The reason for the crash was that I had hook the function objectAtIndex for NSMutableArray.And If user switch from background,the app would get a crash -[UIKeyboardLayoutStar release]: message sent to deallocated.

因此删除钩子代码将解决此错误.

So remove the hook code will resolve this bug.
