I implemented a Spotify player this summer, and indeed you have to use their SDK (https://github.com/spotify/ios-sdk).

Without logging in you can only play the 30 second previews of the songs, only when you are logged in you can play the full songs. The previews can (have to) be played with the iOS audio classes, the full songs when logged in have to be played with the SDK's own player.
