崩溃后出现此错误:
malloc: *** error for object 0x75617b4: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
2013-02-05 19:15:44.950 BusinessIdea[3171:15e03] *** Terminating app due to uncaught exception 'NSGenericException', reason: '*** Collection <__NSSetM: 0x72dc5c0> was mutated while being enumerated.'
我不熟悉这个错误。知道它可能是什么吗?
