我正在创建音乐应用。该应用程序需要检索有关轨道、专辑和艺术家的信息。它当前显示那个 atm。我正在使用最后一个 FM。但是，我想添加 Spotify，以便它可以检索轨道进行播放。
我想添加轨道的预览，这样当用户在应用程序上单击轨道时，他们会单击播放并播放歌曲(预览)。我想打开另一个 xib 来预览这首歌。我已经为我的应用程序提供了代码。截图显示它是如何流动的。
这是我的第一个应用程序，请帮助。我不知道如何合并 Spotify。非常感谢任何可以提供帮助的人。

使用 CocoaLibSpotify 库将 Spotify 与 iOS 或 macOS 集成。
查看 GitHub 上 CocoaLibSpotify 项目中的“Guess The Intro”示例项目。该项目播放歌曲列表中的 15 秒样本。您应该能够根据自己的需要调整它。
