SoundCloud API iOS, no sharing - listening only

Question

I have a website where I create playlists with SoundCloud. Now I want to make an iPhone app so that users can listen to songs there.

http://developers.soundcloud.com/docs/api/ios-quickstart In the example in the link, users must log in to listen and share, but I want my users to only listen. Is there any way that they cannot enter?

Answer 1

Create a page that displays the playlist in JSON, and then in xcode create a class that loads JSON for track dictionaries and plays the downloaded content using AVPlayer (or AVQueuePlayer if you play the entire list).

Here is some abstract code:

playlistDownloader.m - (void)downloadPlaylist{ dispatch_queue_t concurrentQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0); dispatch_sync(concurrentQueue, ^{ NSURL *url = [NSURL URLWithString:@"http://www.yourwebsite.com/playlist.json?id=1"]; NSData *data = [NSData dataWithContentsOfURL:url]; NSError *error; id trackData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error]; if (!error) { tempTrackArray = trackData; } else { NSLog(@"Playlist wasn't able to download"); } }); } 

tempTrackArray will be the declaration declared in the class.

Then in your player you will do something like this:

 audioPlayer.m - (void)instanciateAudioPlayer { NSDictionary *trackDictionary = [playListDownloader.tempTrackArray objectAtIndex:0]; NSString *urlString = [trackDictionary objectForKey:@"stream_url"]; AVAsset *asset = [AVAsset assetWithURL:streamURL]; AVPlayerItem *playerItem = [AVPlayerItem playerItemWithAsset:asset]; [avPlayer initWithPlayerItem:playerItem]; } 

This is some really crude code, but its general meaning is what you are trying to do. Should make you go in the right direction.

Having tried the quick start of soundcloud, I realized that your stream should start with https, not http. You also need to add your client ID from the sound cloud application to the stream URL:

 NSDictionary *trackDictionary = [playListDownloader.tempTrackArray objectAtIndex:0]; NSString *streamURL = [trackDictionary objectForKey:@"stream_url"]; streamURL = [streamURL stringByReplacingOccurrencesOfString:@"http" withString:@"https"]; NSString *urlString = [NSString stringWithFormat:@"%@?client_id=%@", streamURL, @"a8e117d3fa2121067e0b29105b0543ef"]; 

From there, you simply install AVPlayer:

 self._avPlayer = [AVPlayer playerWithURL:[NSURL URLWithString:urlString]]; [self setupLayer:clayer]; [self._avPlayer play]; 

Everything should work fine. Hope this helps.
