iOS应用意外关闭

Question

我的iOS应用程序有问题我无法解决。当其他应用程序打开时（甚至是后台应用程序），它会一直退出，有时整个iPhone会重新启动。

使用xCode提供的分析工具查看时，似乎“ImageIO_JPEG_Data”使用了所有可用的ram。

我附上了探查器中的图像。如果您还有其他需要请告诉我!!

编辑：找到了！这是导致它的代码

-(void)downloadFromURL:(NSString *)url withPlaceholder:(UIImage *)placehold
{
    if (placehold) {
        [self setImage:placehold];
    }
    if (url) {


        if ([url rangeOfString:@"/Library/"].location != NSNotFound) {
            NSData *imageData=[NSData dataWithContentsOfFile:url];
            UIImage* image = [[UIImage alloc] initWithData:imageData];
            if (image) {
                [self setImage:image];
                [self setNeedsLayout];
            }
            return;
        }

        NSString *strImgName = [[[[url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] componentsSeparatedByString:@"/"] lastObject] retain];
        AppDelegate *app=[[UIApplication sharedApplication]delegate];

        [app applicationCacheDirectoryString];

        // NSString *imagePath = [NSString stringWithFormat:@"%@%@",[[AppDelegate sharedObject]applicationCacheDirectoryString],strImgName];


        NSString *imagePath = [NSString stringWithFormat:@"%@%@",[app applicationCacheDirectoryString],strImgName];

        NSFileManager *fileManager = [NSFileManager defaultManager];

        NSString *aURL=[url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

        if ([fileManager fileExistsAtPath:imagePath]==NO)
        {
            dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul);
            dispatch_async(queue, ^(void) {

                NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:aURL]];
                [imageData writeToFile:imagePath atomically:YES];

                UIImage* image = [[UIImage alloc] initWithData:imageData];
                if (image) {
                    dispatch_async(dispatch_get_main_queue(), ^{
                        [self setImage:image];
                        [self setNeedsLayout];

                    });
                }
            });
        }
        else{
            NSData *imageData=[NSData dataWithContentsOfFile:imagePath];
            UIImage* image = [[UIImage alloc] initWithData:imageData];
            if (image) {
                [self setImage:image];
                [self setNeedsLayout];
            }
        }
    }
}

显然这不是我的代码中的错误导致它，不知何故我使用的sqlite数据库已损坏并删除应用程序并重新安装它似乎已修复它。
