使用Apple Music API創建播放列表？

Question

我正在致力於爲iOS app(swift)提供一種更快捷的方式讓用戶從Apple Music library創建播放列表。在閱讀文檔後，我仍然無法弄清楚如何獲取用戶庫。

有沒有一種方法可以訪問用戶庫中的所有歌曲，並將歌曲ID添加到array？

Answer 1

要訪問Apple的音樂庫，您需要將「隱私 - 媒體庫使用說明」添加到您的info.plist。然後你需要讓你的類符合MPMediaPickerControllerDelegate。要顯示Apple音樂庫，請出示MPMediaPickerController。要將歌曲添加到數組中，可以實現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) 
     } 
    }
