objective-c - YouTube Objective-C HTTP POST请求评论

我正在尝试通过我的应用向YouTube视频添加评论，但显然不起作用。然后我去了Api v2网站，看到了:



但这并没有给我任何返回，也没有发表评论。
那么，我必须将发帖请求发送到哪里？我必须写些什么？

到目前为止，这是我的代码:

SBJsonParser *parser = [[SBJsonParser alloc] init];

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

NSString *requestString = [NSString stringWithFormat:@"<?xml version='1.0' encoding='UTF-8'?><entry xmlns='http://www.w3.org/2005/Atom'xmlns:yt='http://gdata.youtube.com/schemas/2007'><content>%@</content></entry>", [textField text]];

NSData *postData = [requestString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];

[request setURL:[NSURL URLWithString:@"https://gdata.youtube.com/feeds/api/videos/FejWBVt7jtk/comments"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/atom+xml" forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSString stringWithFormat:@"Bearer %@", [defaults objectForKey:@"accessToken"]] forHTTPHeaderField:@"Authorization"];
[request setValue:@"key=DEVELOPER KEY" forHTTPHeaderField:@"X-GData-Key"];

[request setHTTPBody:postData];

NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

NSString *content = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

NSDictionary *dict = [parser objectWithString:content];
NSLog(@"%@", dict);

谢谢!

最佳答案

不完全确定您的问题是什么，但是使用Google's Objective-C library可能会更好。
