YouTube Objective-C API video url from playlist item - ios

Question

I am having trouble getting the video url for a YouTube video. I can retrieve the playlist items with a thumbnail and title but I can't get the actual video url.
GTLServiceYouTube *service = [[GTLServiceYouTube alloc] init];
service.APIKey = #"API Key";
GTLQueryYouTube *query = [GTLQueryYouTube queryForPlaylistItemsListWithPart:#"snippet,contentDetails"];
query.playlistId = #"playlist ID";
query.maxResults = 50;
GTLServiceTicket *ticket = [service executeQuery:query
completionHandler:^(GTLServiceTicket *ticket, id object, NSError *error) {
// This callback block is run when the fetch completes
if (error == nil)
{
GTLYouTubeSearchListResponse *products = object;
for (GTLYouTubeSearchResult *item in products)
{
NSLog(#"%#", item.snippet);
NSString *dictionary = [item.snippet JSONValueForKey:#"videoId"];
GTLYouTubeThumbnailDetails *thumbnails = item.snippet.thumbnails;
GTLYouTubeThumbnail *thumbnail = thumbnails.high;
NSString *thumbnailString = thumbnail.url;
if (thumbnailString != nil)
{
[self.thumbnailsArray addObject:thumbnailString];
[self.thumbnailTitleArray addObject:item.snippet.title];
//[self.videos addObject:video];
NSLog(#"id: %#", dictionary);
}
}
}
else
{
NSLog(#"Error: %#", error.description);
}
[self.tableView reloadData];
}];
Does anyone know how to get the video url using the YouTube API?

Answer 1

First of all if you want only videos in your search result you should set type = video.
In your code:
query.playlistId = #"playlist ID";
query.maxResults = 50;
query.type = #"video";
You need to add "id" into part. Your query call will be:
GTLQueryYouTube *query = [GTLQueryYouTube queryForPlaylistItemsListWithPart:#"id,snippet,contentDetails"];
and in response you can get video id with id.videoId. So in your code it will be:
NSString *videoId = item.identifier.videoId;
Once you have the id, you can plug it in:
http://www.youtube.com/watch?v={VIDEO ID HERE}

Answer 2

The video resource in the v3 API does not provide a URL. What you can do instead is to append the video ID to a string. Play page URLs tend to be of the format:
http://www.youtube.com/watch?v={VIDEO ID HERE}
