Question

我已经查看了Youtube的文档，但我似乎并不了解如何为用户专门为ios创建播放列表。我知道用户需要使用OAuth 2登录才能授予应用访问/权限以创建播放列表

文档链接：https://developers.google.com/youtube/v3/sample_requests#uploaded_videos

但是后来给出了这段代码：

POST {base_URL}/playlists?part=snippet
 Request body:
{
'snippet': {
  'title': 'New playlist', 
  'description': 'Sample playlist for Data API',
 }
}

我不确定如何将其翻译为适用于ios。我如何在目标c中反映Request body对象？

------- -----更新它只是使用NSURLSessionUploadTask吗？所以我可以发送一个帖子请求，并发送请求正文的字典？ sry，IOS空间有点新鲜

这是更新！

Google的客户端库已更新。

文档：YouTube Data API Overview

播放列表文档：Playlists: insert

GitHub客户端库：Google APIs Client Library for Objective-C For REST

以下是需要安装的pod：

pod 'GTMSessionFetcher'
pod 'GTMOAuth2'
pod 'GoogleAPIClientForREST/YouTube’

如果我们认为我们有clientID，clientSecret和scope（阅读文档），那么我们可以创建viewController进行身份验证：

GTMOAuth2ViewControllerTouch *viewController = [[GTMOAuth2ViewControllerTouch alloc]
                                                    initWithScope:scope
                                                    clientID:kMyClientID
                                                    clientSecret:kMyClientSecret
                                                    keychainItemName: nil
                                                    completionHandler:
                                                    ^(GTMOAuth2ViewControllerTouch *viewController, GTMOAuth2Authentication *auth, NSError *error) {
                                                        [self dismissViewControllerAnimated:NO completion:nil];
                                                        if (!error)
                                                        {
                                                            GTLRYouTubeService *youTubeService = [[GTLRYouTubeService alloc] init];
                                                            youTubeService.authorizer = auth;
                                                            [self createPlaylistWithTitle: @"Title" description: @"description" youtubeService: youtubeService];
                                                        }
                                                    }];
[self presentViewController:viewController animated:YES completion:nil];

创建私人播放列表的方法：

- (void)createPlaylistWithTitle:(NSString *)playlistTitle description:(NSString *)playlistDescription youtubeService:(GTLRYouTubeService *)youTubeService
{
    GTLRYouTube_Playlist *playlist = [[GTLRYouTube_Playlist alloc] init];

    GTLRYouTube_PlaylistSnippet *playlistSnippet = [[GTLRYouTube_PlaylistSnippet alloc] init];
    playlistSnippet.title = playlistTitle;
    playlistSnippet.descriptionProperty = playlistDescription;

    GTLRYouTube_PlaylistStatus *playlistStatus = [[GTLRYouTube_PlaylistStatus alloc] init];
    playlistStatus.privacyStatus = @"private";

    playlist.snippet = playlistSnippet;
    playlist.status = playlistStatus;

    GTLRYouTubeQuery_PlaylistsInsert *query = [GTLRYouTubeQuery_PlaylistsInsert queryWithObject:playlist part:@"snippet,status"];
    [youTubeService executeQuery:query completionHandler:^(GTLRServiceTicket *ticket, id object, NSError *error) {
        if (!error)
        {
            NSLog(@"response: %@", object);
        }
    }];
}

您是对的，您需要授予应用访问权限才能使用OAuth 2.0创建播放列表。通常最佳做法是在需要访问而不是预先访问时逐步请求范围。

以下是如何在IOS中通过YouTube API创建播放列表的代码段：

GTMOAuth2ViewControllerTouch *viewController = [[GTMOAuth2ViewControllerTouch alloc]
initWithScope:scope
clientID:clientId
clientSecret:clientSecret
keychainItemName:keychainItemName
completionHandler:
^(GTMOAuth2ViewControllerTouch *viewController, GTMOAuth2Authentication *auth, NSError *error) {
if (error) {
[SVProgressHUD showErrorWithStatus:error.localizedDescription];
} else {
GTLServiceYouTube *service = [FZMYoutubeSearchService sharedYoutubeService];
service.authorizer = auth;

GTLYouTubePlaylist *playlist = [[GTLYouTubePlaylist alloc] init];

GTLYouTubePlaylistSnippet *playlistSnippet = [[GTLYouTubePlaylistSnippet alloc] init];
playlistSnippet.title = @"this is my great playlist";
playlistSnippet.descriptionProperty = @"and this is description";

GTLYouTubePlaylistStatus *playlistStatus = [[GTLYouTubePlaylistStatus alloc] init];
playlistStatus.privacyStatus = @"private";

playlist.snippet = playlistSnippet;
playlist.status = playlistStatus;

GTLQueryYouTube *query = [GTLQueryYouTube    queryForPlaylistsInsertWithObject:playlist part:@"snippet,status"];
[service executeQuery:query completionHandler:^(GTLServiceTicket *ticket,      id object, NSError *error) {
if (error) {
NSLog(@"error: %@", error);
