YouTube视频GData API

我试图让YouTube在我的iOS应用程序中运行。我正在成功检索特定用户的视频列表，但我努力实现didSelectRowAtIndexPath，以便将所选视频嵌入到单独的viewController中。这里是我遇到的麻烦的代码：YouTube视频GData API

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 
DetailViewController *detailController = [self.storyboard instantiateViewControllerWithIdentifier:@"DetailController"]; 

    GDataEntryBase *entry2 = [[feed entries] objectAtIndex:indexPath.row]; 
    videoArray = [[(GDataEntryYouTubeVideo *)entry2 mediaGroup] mediaContents]; 
    NSString *tempUrl = [videoArray objectAtIndex:0]; 
    NSLog(@"The URL is:%@",tempUrl); 
    detailController.videoString = tempUrl; 

    [self.navigationController pushViewController:detailController animated:YES]; 

}

我每次运行此，我得到一个断点“detailController.videoString = tempUrl;”

我能看到tempUrl字符串被填充通过的NSLog如下：

The URL is:GDataMediaContent 0x69c76a0: {url:https://www.youtube.com/v/s36krFdPmYQ?version=3&f=user_uploads&app=youtube_gdata type:application/x-shockwave-flash medium:video isDefault:true expression:full duration:1913}

我怎样才能从API的GData只提取视频网址？

在此先感谢您的回复。

我做了以下修改，现在我得到一个正确的URL字符串：

GDataEntryBase *entry2 = [[feed entries] objectAtIndex:indexPath.row]; 
    NSArray *mediaContents = [[(GDataEntryYouTubeVideo *)entry2 mediaGroup] mediaContents]; 
    GDataMediaContent *flashContent = [GDataUtilities firstObjectFromArray:mediaContents withValue:@"application/x-shockwave-flash" forKeyPath:@"type"]; 
    NSLog(@"The URL is:%@",[flashContent URLString]); 
    detailController.videoString = [flashContent URLString];

这使我从NSLog的以下内容：

The URL is:https://www.youtube.com/v/s36krFdPmYQ?version=3&f=user_uploads&app=youtube_gdata

我仍然然而，在获得一个断点“ detailController.videoString = [flashContent URLString];

我能解决这个问题。我在两个ViewControllers之间添加了Modal segue，并稍微修改了我的代码。下面是我最终加入SEGUE后使用的代码：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 
    DetailViewController *detailController = [self.storyboard instantiateViewControllerWithIdentifier:@"DetailController"]; 
    GDataEntryBase *entry2 = [[feed entries] objectAtIndex:indexPath.row]; 
    NSString *title = [[entry2 title] stringValue]; 
    NSArray *contents = [[(GDataEntryYouTubeVideo *)entry2 mediaGroup] mediaContents]; 
    GDataMediaContent *flashContent = [GDataUtilities firstObjectFromArray:contents withValue:@"application/x-shockwave-flash" forKeyPath:@"type"]; 
    NSString *tempURL = [flashContent URLString]; 

    detailController.videoString = tempURL; 
    detailController.titleString = title; 
    [self.navigationController pushViewController:detailController animated:YES]; 

}
