美好的一天,我是Youtube GData api的新手,我无法访问特定播放列表的视频列表。
我首先做的是获取特定用户的播放列表列表。它返回了类似GDataEntryYouTubePlaylistLink 0x888ea20: {v:2.1 title:Playlist Title summary: contentSrc:https://gdata.youtube.com/feeds/api/playlists/PL5......92D127 etag:W/"D04N.....WhJVEU8." authors:1 categories:1 links:related,alternate,self id:tag:youtube.com,2008:user:MyYoutubeUser:playlist:PL5......92D127 countHint:7 unparsed:<media:group>}
我了解到countHint是该播放列表中的视频数量。现在,我想收看这些视频。
我尝试创建一个可以这样做的函数,但我不知道我将使用什么FeedID:
GDataServiceGoogleYouTube *service = [self youTubeService];
NSString *feedID = kGDataYouTubeUserFeedIDPlaylists; //this was the feedID i used to get the list of playlist of a user
NSURL *feedURL = [GDataServiceGoogleYouTube youTubeURLForUserID:@"MyYoutubeUser"
userFeedID:feedID];
[service fetchFeedWithURL:feedURL
delegate:self
didFinishSelector:@selector(request:finishedLoading:error:)];
答案 0 :(得分:1)
我能够找到解决问题的方法。我希望它也可以帮到你。
在我的viewDidLoad中,我调用了loadYoutube和loadYoutubePlaylist函数。
这就是代码的样子:
- (void)loadYoutube
{
GDataServiceGoogleYouTube *service = [self youTubeService];
NSString *uploadsID = kGDataYouTubeUserFeedIDUploads;
NSURL *feedURL = [GDataServiceGoogleYouTube youTubeURLForUserID:@"USERNAME"
userFeedID:uploadsID];
NSLog(@"loadYoutube URL: %@", feedURL);
[service fetchFeedWithURL:feedURL
delegate:self
didFinishSelector:@selector(request:finishedLoadingYoutubeWithFeed:error:)];
}
- (void)loadYoutubePlaylist
{
GDataServiceGoogleYouTube *service = [self youTubeService];
NSString *feedID = kGDataYouTubeUserFeedIDPlaylists;
NSURL *feedURL = [GDataServiceGoogleYouTube youTubeURLForUserID:@"USERNAME"
userFeedID:feedID];
NSLog(@"loadYoutubePlaylist URL: %@", feedURL);
[service fetchFeedWithURL:feedURL
delegate:self
didFinishSelector:@selector(request:finishedLoadingPlaylistWithFeed:error:)];
}
- (void)loadYoutubeVideosPerPlaylist:(NSString *)urlString
{
GDataServiceGoogleYouTube *service = [self youTubeService];
NSURL *feedURL = [NSURL URLWithString:urlString];
NSLog(@"loadYoutubeVideosPerPlaylist URL: %@", feedURL);
[service fetchFeedWithURL:feedURL
delegate:self
didFinishSelector:@selector(request:finishedLoadingYoutubeVideosPerPlaylistWithFeed:error:)];
}
以下是Youtube的请求..

}
