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

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?
回答1:
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
.
So remove the hook code will resolve this bug.
