在 UIViewController 上实现 TTThumbsViewController？

Question

我尝试将 TThumbsViewController 添加为 UIViewController 的子视图，但应用程序崩溃了。在这里您可以看到代码

- .h 文件

#import <UIKit/UIKit.h>
#import <Three20/Three20.h>
#import <Three20UI/UIViewAdditions.h>
#import "MockPhotoSource.h"

@interface photos : UIViewController <NSXMLParserDelegate, TTThumbsViewControllerDelegate>
{
    TTThumbsViewController *photoSource;
...........
}

- .m 文件-

    - (void)viewDidLoad {

// parsing a feed
[self parseXMLFileAtURL:@"http://feed203.photobucket.com/albums/aa15/vikysaran/Worst%20Parents/feed.rss"];

    NSMutableArray *arr = [[NSMutableArray alloc]init];                         

    for (int i=0; i < [stories count];i++) {

        [arr addObject:[[[MockPhoto alloc] initWithURL:[[stories objectAtIndex:i] objectForKey:@"fullimageurl"] smallURL:[[stories objectAtIndex:i] objectForKey:@"thumburl"]
 size:CGSizeMake(960, 1280)] autorelease]];
    }
    photoSource = [[[MockPhotoSource alloc] initWithType:MockPhotoSourceNormal title:nil photos:[NSArray arrayWithArray:arr] photos2:nil]autorelease];
// till here the code is working fine if i am not using uiviewcontroller
        NSLog(@"mockphoto%@", arr);

        [self.view addSubview:photoSource.view];// adding to uiview
    }

这是错误显示-

-[MockPhotoSource view]: unrecognized selector sent to instance 0x6924ca0
2011-09-22 13:07:07.375 JesonTerry[1969:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MockPhotoSource view]: unrecognized selector sent to instance 0x6924ca0'

请任何人帮忙。我完全困惑我哪里错了......

对于初学者来说，您的视图控制器必须是 TTThumbsViewController 类型，而不是 UIViewControler 类型。检查示例文件夹中的 TTCatalog 应用程序
