我正在尝试从服务器下载图像并显示在 320 库的 TTThumbsViewController 中。我无法让这个工作！

当我在本地存储图像时，以下对我有用：

    //Create thumbnails
    [ImageUtils checkAndSaveThumbnail:imageName andSize:CGSizeMake(100.0, 100.0) andLocation:NO andPrefixof:@"small"];

    NSString *fullImageName = [NSString stringWithFormat:@"documents://%@",imageName];
    NSString *imageSmallName = [NSString stringWithFormat:@"documents://small-%@",imageName];
    NSString *caption = [tempDict objectForKey:@"Comment"];

    UIImage *tempImage = [UIImage imageWithContentsOfFile:[appDelegate filePath:imageName]];

    MockPhoto *tempPicture = [[MockPhoto alloc] initWithURL:fullImageName smallURL:imageSmallName size:tempImage.size caption:caption photoname:imageName];

    [photoArray addObject:tempPicture];

将 photoArray 添加到 MockPhotoSource 中：

self.photoSource = [[MockPhotoSource alloc]
                    initWithType:MockPhotoSourceNormal
                    title:@"Photos"     
                    photos:photoArray
                    photos2:nil
                    ];

[photoArray release];

...但是当我像下面这样给出下载位置时它不起作用！不显示缩略图，也不显示大图！

    NSString *url = [delegate downloadImageUrl];

    MockPhoto *tempPicture = [[MockPhoto alloc] initWithURL:url smallURL:url size:tempImage.size caption:caption photoname:imageName];

    [photoArray addObject:tempPicture];

我一直在使用与 AsyncImage 相同的 URL，它可以下载图像并在 ImageView 中很好地显示！

    NSURL *url = [NSURL URLWithString:[delegate downloadImageUrl]];
    UIImageView *profileimage = [[UIImageView alloc] init];
    AsyncImageView* asyncImage = [[[AsyncImageView alloc] initWithFrame:CGRectMake(0, 10, 60, 60)] autorelease];
    asyncImage.imageName = [[users objectAtIndex:indexPath.row] objectForKey:@"Key"];
    [asyncImage loadImageFromURL:url];
    [profileimage addSubview:asyncImage];

你能否让我知道我在使用 MockPhoto 时有什么问题？

谢谢。
