问题
I can not identify the problem from this crash log. I have seen several post about EXC_CRASH (SIGABRT) and CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER but those didn't help either.This happens in OS Version:iOS 8.3 (12F69) and in iPad2.
Exception Type: EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000

回答1:
The stacktrace needs to be symbolicated so you can see what 0x10011c5dc 0x100114000 + 34268 actually means (i.e. what source file and line). See this question for details.
The crash occurs in [NSMutableDictionary setObject:forKey:] and one very common reason for a crash in that method is that the object is nil and you cannot hold nil in Objective-C collection classes. However there should have been some exception text generated which can confirm this.
That's about all I can tell you at this stage.
