내 응용 프로그램이 오류를 얻고있다

tweets 배열라는 배열 아래에있는 instaPics 배열과 공유 totalArray 그래서 내가 fetchInstagramPics 함수를 포함 시켰습니다. 나는 그것이 복잡하게 들리지만, 귀하의 도움은 깊이 감사하게 생각합니다. 여기

당신의 -[AppDelegate didFinishLaunchingWithOptions:] : 모든 방법을 아래 파일의 맨 아래에있는 AppDelegate에에서

#ifdef DEBUG 
    NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler); 
#endif 

:

#ifdef DEBUG 
void uncaughtExceptionHandler(NSException *ex) 
{ 
    NSLog(@"CRASH :\n %@", ex.reason); 
    NSLog(@"STACK TRACE :\n %@", ex.callStackSymbols); 
    exit(0); 
} 
#endif 

이렇게하면 콘솔에 스택 추적이 표시됩니다. 이후에 어떤 함수가 크래시를 일으키고 고치거나 stacktrace를 게시하여 질문을 편집하여 보겠습니다.
EDIT 스택 추적을보고 난 후 [self.instaPics addObjectsFromArray:responseObject[@"data"]];을 입력하면 instaPics = [[NSMutableArray alloc] init];이됩니다. self.instaPics은 변경 불가능한 NSArray입니다. 나도 모르겠다, 당신의 논리가 작동해야하는 방법, 당신은 어느 쪽이든 self.instaPics = [[NSMutableArray alloc] init]; 또는 [instaPics addObjectsFromArray:responseObject[@"data"]];
