我試圖將GData/YouTubeAPI整合到我的項目中，但我有點卡住了。我用的是在這個帖子中給出的代碼：@selector（）不工作？ YouTube的API GData的問題
Any examples/tutorials on using Google GData API - Youtube on iphone?
我的問題是，該功能的要求：finishedWithFeed：錯誤：「當服務的GData完成抓取數據從interwebs不叫。
我的程序編譯並運行 - 並沒有運行時錯誤出現。我也檢查並且feedURL返回一個有效的URL。我調試了這個，'服務'確實設法返回一個值。
GDataServiceGoogleYouTube *service = [self youTubeService];
// feed id for user uploads
NSString *uploadsID = kGDataYouTubeUserFeedIDUploads;
// construct the feed url
NSURL *feedURL = [GDataServiceGoogleYouTube youTubeURLForUserID:USER_NAME userFeedID:uploadsID];
// make API call
[service fetchFeedWithURL:feedURL delegate:self didFinishSelector:@selector(request:finishedWithFeed:error:)];
這是我想要得到的服務其完成時調用函數的頭，它位於在同一個對象的其他代碼我已經張貼
- (void)request:(GDataServiceTicket *)ticket finishedWithFeed:(GDataFeedBase *)aFeed error:(NSError *)error;
解決方案 - -
確保其在主線程上運行 -
-(id)initWithVideosArrayURLString:(NSString*)url {
if (self = [super init]) {
NSLog(@"loading");
[self performSelectorOnMainThread:@selector(initMainThreadWithURLString:) withObject:url waitUntilDone:NO];
}
return self;
}
-(void)initMainThreadWithURLString:(NSString*)url {
GDataServiceGoogleYouTube *service = [self youTubeService];
NSString *uploadsID = kGDataYouTubeUserFeedIDUploads;
NSURL *feedURL = [GDataServiceGoogleYouTube youTubeURLForUserID:@"annoyingorange" userFeedID:uploadsID];
[service fetchFeedWithURL:feedURL delegate:self didFinishSelector:@selector(serviceTicket:finishedWithFeed:error:)];
NSLog(@"sent");
}
- (void)serviceTicket:(GDataServiceTicket *)ticket finishedWithFeed:(GDataFeedBase *)aFeed error:(NSError *)error {
self.feed = (GDataFeedYouTubeVideo *)aFeed;
NSLog(@"success.");
}
