POYoutube integration with iOS app - unexpected error

Body
copied!<p><br> I'm following this example <a href="https://code.google.com/p/google-api-objectivec-client/source/browse/#svn/trunk/Examples/YouTubeSample" rel="nofollow">https://code.google.com/p/google-api-objectivec-client/source/browse/#svn/trunk/Examples/YouTubeSample</a> to integrate YouTube SDK into my iOS app.<br> Here are some jobs I have done:<br> - Add the GTL.project into my project and set the source path for Header Search Path.<br> - Link the GTLTouchStaticLib to Link Binary with Libraries of my project.<br> - Add GTLYouTube_Sources.m into my project.<br> - Copy some codes from YouTubeSample, here is the code snippet:<br></p> <pre><code>#import "ViewController.h" #import "GTLYouTube.h" #import "GTLUtilities.h" #import "GTMHTTPUploadFetcher.h" #import "GTMHTTPFetcherLogging.h" #import "GTMOAuth2ViewControllerTouch.h" . . - (IBAction)Login:(id)sender { GTMOAuth2ViewControllerTouch *viewController; viewController = [[GTMOAuth2ViewControllerTouch alloc] initWithScope:kGTLAuthScopeYouTube clientID:kMyClientID clientSecret:kMyClientSecret keychainItemName:kKeychainItemName delegate:self finishedSelector:@selector(viewController:finishedWithAuth:error:)]; [self presentViewController:viewController animated:YES completion:NULL]; } - (void)viewController:(GTMOAuth2ViewControllerTouch *)viewController finishedWithAuth:(GTMOAuth2Authentication *)auth error:(NSError *)error { if (error == nil) { self.youTubeService.authorizer = auth; // [self dismissViewControllerAnimated:YES completion:NULL]; [self fetchMyChannelList]; } else { NSLog(@"Auth failed: %@", error); } } - (void)fetchMyChannelList { NSLog(@"fetchMyChannelList"); _myPlaylists = nil; _channelListFetchError = nil; GTLServiceYouTube *service = self.youTubeService; GTLQueryYouTube *query = [GTLQueryYouTube queryForChannelsListWithPart:@"contentDetails"]; query.mine = YES; // maxResults specifies the number of results per page. Since we earlier // specified shouldFetchNextPages=YES, all results should be fetched, // though specifying a larger maxResults will reduce the number of fetches // needed to retrieve all pages. query.maxResults = 50; // We can specify the fields we want here to reduce the network // bandwidth and memory needed for the fetched collection. // // For example, leave query.fields as nil during development. // When ready to test and optimize your app, specify just the fields needed. // For example, this sample app might use // // query.fields = @"kind,etag,items(id,etag,kind,contentDetails)"; _channelListTicket = [service executeQuery:query completionHandler:^(GTLServiceTicket *ticket, GTLYouTubeChannelListResponse *channelList, NSError *error) { // Callback // The contentDetails of the response has the playlists available for // "my channel". if ([[channelList items] count] > 0) { GTLYouTubeChannel *channel = channelList[0]; _myPlaylists = channel.contentDetails.relatedPlaylists; NSLog(@"_myPlaylists: %@", _myPlaylists); } _channelListFetchError = error; _channelListTicket = nil; if (_myPlaylists) { [self fetchSelectedPlaylist];
