极高的匿名虚拟机和应用程序崩溃

Question

我有一个很大的问题，我无法处理。我的应用程序使用iBeacons来显示视图并加载存储在CoreData中的一些图片，但是，这不是真正的问题。 我将一些pics从解析加载到核心数据，然后从核心数据中检索以显示。

当我从一个视图更改为另一个视图时，我认为它可以增加，但是当我退出视图时，可以释放内存吗？我不知道它我解释得很好，但我希望你能理解我并尽可能多地帮助我。

我在iPad上使用Xcode 5.1.1和iOS 7.1

现在我正在使用乐器试着看看发生了什么，这就是我得到的。

分配：

我认为我做错了，加载这样的图片，不知道问题是什么：_（

self.itemsSection1 = [[NSMutableArray alloc] init];
    self.generalImages1 = [[NSMutableArray alloc] init];
    [self fillArraysWithItems:self.itemsSection1 section:@"1"];
    [self fillArraysWithGeneralImages:self.generalImages1 section:@"1"];
    self.itemImages = [NSArray
                       arrayWithObjects:[UIImage imageWithData:self.itemsSection1[0][@"image"]],
                       [UIImage imageWithData:self.itemsSection1[1][@"image"]],
                       [UIImage imageWithData:self.itemsSection1[2][@"image"]],
                       [UIImage imageWithData:self.itemsSection1[3][@"image"]],
                       [UIImage imageWithData:self.itemsSection1[4][@"image"]], nil];
    for (int i=0; i<self.generalImages1.count; i++) {
        [self.itemSliderImages addObject:[UIImage imageWithData:self.generalImages1[i][@"image"]]];
    }
    generalImage.image = [UIImage imageWithData:self.generalImages1[0][@"image"]];
    self.img_elements.image = generalImage.image;
    self.navBar_title.title = @"Catering";

FillArraysWithItems：

    -(void)fillArraysWithItems: (NSMutableArray*)item section:(NSString*)section{

    AppDelegate *delegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];
    NSEntityDescription *entity = [NSEntityDescription entityForName:@"Item" inManagedObjectContext:delegate.managedObjectContext];

    NSFetchRequest *fetchedRequest = [[NSFetchRequest alloc]init];
    [fetchedRequest setEntity:entity];

    self.allItemInfo = [[delegate.managedObjectContext executeFetchRequest:fetchedRequest error:nil] mutableCopy];
    NSLog(@"\n\nAllItems:%@\n", self.allItemInfo);
    for (NSManagedObjectContext *obj in self.allItemInfo) {
        //Save data from CoreData to arrays
        NSLog(@"\n\nObject:\n%@", obj);
        NSString *micro = @"micro_off.png";
        NSString *oven = @"oven_off.png";
        NSString *recycle = @"recycle_off.png";
        NSString *biodeg = @"biodeg_off.png";
        NSString *liquid = @"liquid_off.png";
        NSString *perso = @"perso_off.png";
        NSLog(@"\n\nName:%@\nRef:%@\nPricePack:%@\nUnitPrice:%@\nunitsPack:%@",[obj valueForKey:@"name"], [obj valueForKey:@"reference"],[obj valueForKey:@"pricePack"], [obj valueForKey:@"priceUnity"], [obj valueForKey:@"unitsPack"]);

        if ([[obj valueForKey:@"section"] isEqual:section]) {
            if ([[obj valueForKey:@"micro"]  isEqual: @1]) {
                micro = @"micro_on.png";
            }
            if ([[obj valueForKey:@"oven"] isEqual: @1]) {
                oven = @"oven_on.png";
            }
            if ([[obj valueForKey:@"recycle"] isEqual: @1]) {
                recycle = @"recycle_on.png";
            }
            if ([[obj valueForKey:@"bio"] isEqual: @1]) {
                biodeg = @"biodeg_on.png";
            }
            if ([[obj valueForKey:@"liquid"] isEqual: @1]) {
                liquid = @"liquid_on.png";
            }
            if ([[obj valueForKey:@"perso"] isEqual: @1]) {
                perso = @"perso_on.png";
            }
            [item addObject:@{@"name": [obj valueForKey:@"name"],
                              @"pricePack": [obj valueForKey:@"pricePack"],
                              @"priceUnity": [obj valueForKey:@"priceUnity"],
                              @"reference": [obj valueForKey:@"reference"],
                              @"unitsPack": [obj valueForKey:@"unitsPack"],
                              @"micro": [UIImage imageWithContentsOfFile:micro],
                              @"oven": [UIImage imageWithContentsOfFile:oven],
                              @"recycle": [UIImage imageWithContentsOfFile:recycle],
                              @"bio": [UIImage imageWithContentsOfFile:biodeg],
                              @"liquid": [UIImage imageWithContentsOfFile:liquid],
                              @"perso": [UIImage imageWithContentsOfFile:perso],
                              @"image": [UIImage imageWithContentsOfFile:[obj valueForKey:@"image"]]}];
        }
    }
    NSError *error;
    BOOL isFetched = [delegate.managedObjectContext save:&error];
    NSLog(@"Arrays successfully filled: %d", isFetched);
}

这是[item addObject ...

时出现的错误
