To make it easier to see where the crash is originating, change your main.m file as follows:

int main(int argc, char* argv[])
{
    @autoreleasepool
    {
        int returnValue;
        @try
        {
            returnValue = UIApplicationMain(argc, argv, nil, 
                NSStringFromClass([MyAppDelegate class]));
        }
        @catch (NSException* exception)
        {
            LogError(@"Uncaught exception: %@, %@", [exception description], 
                [exception callStackSymbols]);
            @throw exception;
        }
        return returnValue;
    }
}

. . . or as others have suggested, set an exception breakpoint.

If your crash is only happening "in the wild" you'll have to resymbolicate your crash logs. Services like Hockey or Test Flight do this for you, or it can be done manually following this process.
