我正在玩谷歌的object-c API(Gdata)與youtube進行交互(在我的情況下),但我遇到了問題。我試圖搜索YouTube視頻與查詢類:iPhone Gdata-client Youtube查詢不起作用

NSURL *feedURL = [GDataServiceGoogleYouTube youTubeURLForFeedID:nil]; 
    GDataQueryYouTube *query = [GDataQueryYouTube youTubeQueryWithFeedURL:feedURL]; 


    [query setVideoQuery:@"\"Fred Flintstone\""]; 

    ticket = [service fetchFeedWithQuery:query 
           delegate:self 
         didFinishSelector:@selector(entryListFetchTicket:finishedWithFeed:)]; 


    [ticket setShouldFollowNextLinks:NO]; 

但是,當我執行它,我有在CONSOL這個錯誤(回撥entryListFetchTicket甚至不叫)

我不知道爲什麼...

但是,如果我使用的超視距雷達的手養活它的工作原理...

NSURL *feedURL; 
    feedURL = [GDataServiceGoogleYouTube youTubeURLForFeedID:kGDataYouTubeFeedIDMostPopular]; 


    ticket = [service fetchFeedWithURL:feedURL 
           delegate:self 
        didFinishSelector:@selector(entryListFetchTicket:finishedWithFeed:error:)]; 


    [ticket setShouldFollowNextLinks:NO] 

可以somedyoy給我一隻手嗎?

感謝

你真的定義在類中的方法entryListFetchTicket:finishedWithFeed:您正在使用作爲委託對象?

GData提取的回調有三個參數,而不是兩個。第一個代碼片段缺少錯誤:在選擇器的末尾。

確保爲您的調試版本定義DEBUG = 1;圖書館將抓住這些問題。
