我在iPad上有一個應用程序崩潰導致重新啓動。這種崩潰的方法showMap後會發生什麼地方:(Mappe * mappa):iPad應用程序崩潰導致重新啓動內存問題?

- (void)viewDidLoad { 
    moc = [[MapFetcher sharedInstance] managedObjectContext]; 
    [NSThread detachNewThreadSelector:@selector(fetchMap) toTarget:self withObject:nil]; 

    [super viewDidLoad]; 
} 

- (void)fetchMap { 
    NSAutoreleasePool *threadPool = [[NSAutoreleasePool alloc] init]; 

    Mappe *mappa; 

    mappa = [[[MapFetcher sharedInstance] fetchManagedObjectsForEntity:@"Mappe" 
                withPredicate:[NSPredicate predicateWithFormat:@"Citta == %@", map] 
                withDescriptor:@"Citta"] objectAtIndex:0]; 
    [self performSelectorOnMainThread:@selector(showImage:) withObject:mappa waitUntilDone:YES]; 

    [threadPool release]; 

} 

- (void)showImage:(Mappe *)mappa { 
    imvMappa = [[UIImageView alloc] initWithFrame:CGRectMake(0.0, 0.0, 1024.0, 704.0)]; 
    [imvMappa setImage:[UIImage imageWithData:[mappa Mappa]]]; 
    [scrollView addSubview:imvMappa]; 
    [scrollView setContentSize:CGSizeMake(1024.0, 704.0)]; 
    [scrollView setMinimumZoomScale:0.5]; 
    [scrollView setMaximumZoomScale:4.0]; 
    [scrollView setZoomScale:1.0]; 
    [scrollView setContentMode:(UIViewContentModeScaleAspectFit)]; 
    [scrollView setClipsToBounds:YES]; 
    [scrollView setDelegate:self]; 
    [imvMappa release]; 
    [loadingImage stopAnimating]; 
    [waitFor setHidden:YES]; 
    [scrollView setHidden:NO]; 
} 

滾動視圖是一個出口,Mappe是管理對象,因爲我的應用程序在任何地方使用它,它應該工作正常,它不會造成麻煩。 我真的被卡住了,可能會導致crash-n-reboot?


編輯:內存分析

我用儀器 - 內存監視器,看看發生了什麼事情,並告訴在啓動的那一刻,我的應用程序使用17 MB的內存,而分配說:實時字節883 KB,總共4MB。我有點困惑......當我啓動上面的代碼時,我看到:2MB的實時字節(4個ViewControllers)總共22 MB,而Memory Monitor則說77 MB的實際內存。 我應該看到什麼情況的真實報告?
