我需要在 UITableView 中列出特定用户上传的视频 (YouTube).我已经下载了 GData 源和示例项目(不是特定于 iphone 的)，但我似乎无法让它工作.有人知道那里有什么好的(或根本没有 ;))教程吗?

I need to list a specific users uploaded videos (YouTube) in a UITableView. I've downloaded the GData source and example projects (not iphone specific) but I can't seem to get it to work. Does anybody know of any good (or any at all ;)) tutorials out there?

推荐答案

假设您已将 GData 客户端库包含到您的项目中，您需要调用以获取用户上传的内容，然后显示它们.这是我能想到的最简单的方法:

Assuming you have included the GData client libraries to your project, you need to make a call to fetch the user's uploads, and then display them. Here's the simplest way I can think of:

在您的表视图控制器类中创建一个实例变量，用于保存从 YouTube API 返回的提要数据.

Create an instance variable in your table view controller class that will hold the feed data returned from the YouTube API.

#import "GDataYouTube.h"
#import "GDataServiceGoogleYouTube.h"

@interface RootViewController : UITableViewController {
    GDataFeedYouTubeVideo *feed;
}

@property (nonatomic, retain) GDataFeedYouTubeVideo *feed;

在实现文件中，调用 API 以获取所有上传的视频.在回调选择器 request:finishedWithFeed:error 中，以任何适合的格式存储结果，并重新加载表格视图.在表格视图 cellForRowAtIndexPath 方法中，根据需要格式化单元格:

Inside the implementation file, make a call to the API to fetch all uploaded videos. Inside the callback selector request:finishedWithFeed:error, store the results in whatever format suits, and reload the table view. In the table views cellForRowAtIndexPath method, format the cell as desired:

// get the youtube service
GDataServiceGoogleYouTube *service = [self youTubeService];

// feed id for user uploads
NSString *uploadsID = kGDataYouTubeUserFeedIDUploads;
// construct the feed url
NSURL *feedURL = [GDataServiceGoogleYouTube youTubeURLForUserID:@"annoyingorange"
                                            userFeedID:uploadsID];

// make API call
[service fetchFeedWithURL:feedURL
         delegate:self
         didFinishSelector:@selector(request:finishedWithFeed:error:)];
