私は音楽アプリを作成しています。アプリケーションはトラック、アルバム、アーティストの情報を取得する必要があります。最後のFMですが、Spotifyを追加してトラックを再生できるようにしたいのですがSpotify Api：Objective Cの最後のfmアプリにSpotify「プレビュートラック」を追加する方法
トラックのプレビューを追加すると、ユーザがトラックをクリックして再生をクリックすると、それは曲（プレビュー）を再生します。私は、その曲のプレビューを表示する別のxibを開くには、私のアプリケーションのコードを提供しています。 Spotifyをどのように組み込むのか分かりません。 uchは助けることができる人に感謝します。
最後のFmアルバム、トラック、アーティスト情報の検索。
