在 iPhone 上获取当前在 Spotify 中播放的歌曲

Question

访问 MPMusicPlayerController.systemMusicPlayer()（下面的代码）可以获取 Apple Music 应用程序中正在播放的歌曲的曲目信息，但是我们有没有办法可以访问 Spotify 应用程序中正在播放的歌曲的信息？

此答案中发布的代码 I need to know how to get information about which player is currently streaming (player, spotify, napster...) 使用 MPNowPlayingInfoCenter 无论是使用 Apple Music 还是 Spotify 等，它都是 nil

  let player = MPMusicPlayerController.systemMusicPlayer()

    @IBAction func getMusicButton(_ sender: UIButton) {




        if let mediaItem = player.nowPlayingItem {
            let title: String = mediaItem.value(forProperty: MPMediaItemPropertyTitle) as! String
            let albumTitle: String = mediaItem.value(forProperty: MPMediaItemPropertyAlbumTitle) as! String
            let artist: String = mediaItem.value(forProperty: MPMediaItemPropertyArtist) as! String

            print("\(title) on \(albumTitle) by \(artist)")
        }

    }

Answer 1

Apple 文档指出有两种类型的音乐播放器：

• An application music player plays music locally within your app. It is not aware of the Music app’s now-playing item, nor does it affect the Music app’s state. There are two application music players: applicationMusicPlayer and applicationQueuePlayer. The application queue player provides greater control over the contents of the queue and is the preferred player.
• The system music player employs the built-in Music app on your behalf. On instantiation, it takes on the current Music app state, such as the identification of the now-playing item. If a user switches away from your app while music is playing, that music continues to play. The Music app then has your music player’s most recently-set repeat mode, shuffle mode, playback state, and now-playing item.

第一个仅在您的应用程序中，第二个是 Apple Music 应用程序，因为您无法在普通应用程序中超出应用程序的沙箱，这在 App Store 应用程序中是不可能的。

如果您仍然想创建您的想法，您可以在越狱设备上开发它。 This github project has an easy example of how to get the current playing song in a jailbreak tweak. If you want to try it, this 是关于如何开始开发调整的优秀教程，虽然有点旧，但仍然很准确。

我只是 运行 进入 this Spotify SDK，这将让用户登录并播放用户的 Spotify 音乐。这样音乐流将在您的应用程序中，您可以访问 applicationMusicPlayer 中的所有信息。不利之处在于，与仅获取有关 Spotify 播放曲目的信息相比，这将需要更多的设置工作，并且用户将不得不从您的应用程序而不是 Spotify 应用程序播放他的音乐。
