使用 Apple Music API 创建播放列表？ [已关闭]

Question

我正在开发一个

iOS app(swift)

，它为用户提供了一种更快的方式从他们的

Apple Music library

创建播放列表。阅读文档后，我仍然不知道如何访问用户库。

有没有办法可以访问用户库中的所有歌曲并将歌曲 ID 添加到

array

？

Answer 1

要访问 Apple 的音乐库，您需要将“隐私 - 媒体库使用说明”添加到您的 info.plist 中。然后您需要使您的类符合 MPMediaPickerControllerDelegate。要显示 Apple Music 库，您需要提供 MPMediaPickerController。要将歌曲添加到数组中，您可以实现 MPMediaPickerControllerDelegate 的 didPickMediaItems 方法。

    class MusicPicker:UIViewController, MPMediaPickerControllerDelegate {
    //the songs the user will select
    var selectedSongs: [URL]!

    //this method is to display the music library.
    func getSongs() {

    var mediaPicker: MPMediaPickerController?

    mediaPicker = MPMediaPickerController(mediaTypes: .music)

    mediaPicker?.delegate = self

    mediaPicker?.allowsPickingMultipleItems = true

    mediaPicker?.showsCloudItems = false
    //present the music library
    present(mediaPicker!, animated: true, completion: nil)

}

//this is called when the user selects songs from the library
func mediaPicker(_ mediaPicker: MPMediaPickerController, didPickMediaItems mediaItemCollection: MPMediaItemCollection) {
   //these are the songs that were selected. We are looping over the choices
   for mpMediaItem in mediaItemCollection.items {
     //the song url, add it to an array
    let songUrl = mpMediaItem.assetURL
    selectedSongs.append(songURL)
   }
   //dismiss the Apple Music Library after the user has selected their songs
   dismiss(animated: true, completion: nil)

   }
   //if the user clicks done or cancel, dismiss the Apple Music library
   func mediaPickerDidCancel(mediaPicker: MPMediaPickerController) {

          dismiss(animated: true, completion: nil)
        }
   }
