The report I'm getting back from Crashlytics is
Crashed: com.apple.main-thread
SIGABRT ABORT at 0x357fedf0
How do I narrow this mystery crash down?
Also, here's some additional info from Crashlytics

as I see from the logs "pthread_kill" in the stack, I hope that this answer helps you.
Exception Type: EXC_CRASH (SIGABRT)
Related
In my crash log, I see [NSException initWithCoder:] at the top of the crashed stack trace. What's NSException initWithCoder? Why would NSException have this method? Note: I am not interested in knowing the cause of the crash, but why NSException's initWithCoder appears here and what it's doing.

Firstly, the desymbolicated crash log is at the bottom. I cannot post all the content out of privacy reason. However the first 3 threads log is enough I thought, if you really want that please leave a message.
And here is the thing, depending on this article Understanding iOS Exception Types | 5Neo.Be5Neo.Be, the mach exception type -- EXC_CRASH -- is not usual following with the C signal SIGSEGV (which means access an address you don't own).
So I want to know what reason or when will EXC_CRASH (SIGSEGV) appear?
Second question is if this crash is actually trigger by Thread 0 as the log said. And if it's ture, then what does
"__NSThreadPerformPerform"
and
"__CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__"
means?
What action is system doing? By the way, __NSThreadPerformPerform will appear when App call "performSelector:" method according to this answer -- iphone - SIGABRT crash on CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION - Stack Overflow.
Thanks.

This is a bit of a weird one.
In my code, I have this line:
NSMutableArray *unresolvedPlayers = [NSMutableArray arrayWithCapacity:3];
This seems like a perfectly valid line. I crashed on this line with this stack trace (I have replaced my app name with xxxxxxxxx):

How is it possible that my memory has gotten corrupted up to this point that allocating a new NSMutableArray would cause this to happen? I'm not even sure where to start with debugging this one. I am not sure this is easily reproducible.
As a side note, it happened when inviting nearby players to a realtime GameCenter match.
EDIT: I just realized this is crashing on Thread 7. This is what Thread 7 looks like:

So, this is probably a bug with GameCenter.
Crash in objc_msgSend can indicate that message destination object is deallocated already. Try to enable zombie objects and keep your eyes on logs.
My app got rejected by Apple App Store review team because it was crashed on iPad air running iOS 7.1.1, as soon as the app lunches, as they said. They've attached a crash report that I have no idea how to investigate and will appreciate if you can help:

attention to the follows:
Exception Type: EXC_CRASH (SIGABRT)
It is not caused by your code. I think the system send some code like kill to your app.
Maybe the following reason:
Your app has not launched in five seconds.
I tried with many search with the above title and also do as many advice of my search but cannot solved the problem. My app got crash when I build on the iPad which had jail break. But with the device not jail break it worked. Call the below function is the reason for crash:
-(void)btnLoginPressed:(id)sender {
[[MoboAccesstoken ActiveAccessToken] setMoboAccessTokenDelegate:self];
if (![[MoboAccesstoken ActiveAccessToken]isOpened]){
[MoboSDK openActiveSessionWithCompletion:^(NSDictionary *data) {
NSLog(#"data: %#", data);
}];
}
}
and the stack trace is:

Edit:
The crash only happen on iPad(jail break) 5.1.1. With iPad(jail break) 7.0.4 or 6. -> it worked.*
Reason: When I call openActiveSessionWithCompletion function,I do many actions to collect the info to make a url link. It included the action: get UUIDString .And with iOS 5.1 the result when get UUIDString is a NULL string. So that, it's reason for app crash when I call the command: uuid_String = [[NSString alloc]initWithString:[[[ASIdentifierManager sharedManager] advertisingIdentifier] UUIDString]];. initWithString: this function when push a NULL string will make app crash.
This is wrong:
uuid_String = [[NSString alloc]initWithString:[[[ASIdentifierManager sharedManager] advertisingIdentifier] UUIDString]]
Just do this:
uuid_String = [[[ASIdentifierManager sharedManager] advertisingIdentifier] UUIDString];
As for why it returns nil, probably because advertising is disabled on the device. Users are allowed to opt out of tracking.
Check the documentation and beware iOS 5 and 7 have different behaviour.
