我正在尝试播放专辑,使用以下代码...</p>

let predicate = MPMediaPropertyPredicate(value: "1459938538", forProperty: MPMediaItemPropertyAlbumPersistentID)
let iCloudPredicate = MPMediaPropertyPredicate(value: true, forProperty: MPMediaItemPropertyIsCloudItem)
let query = MPMediaQuery.albums()
query.filterPredicates = [predicate, iCloudPredicate]

let mp = MPMusicPlayerController.applicationMusicPlayer
mp.setQueue(with: query)
mp.play()

但它失败了

[SDKPlayback] -[MPMusicPlayerController prepareToPlay] timeout

• 如果我删除谓词,它将正常播放本地专辑。

• <code>SKCloudServiceController.requestAuthorization 是.authorized

• 该设备同时具有.musicCatalogPlayback.addToCloudMusicLibrary功能。

1459938538似乎是一个有效的身份证件(这是最新的麦当娜专辑 - https://music.apple.com/gb/album/madame-x-deluxe/1459938538

关于如何播放不在我的图书馆中的专辑的任何提示?

MPMediaQuery 仅适用于库项目。您需要使用网络 Apple Music 搜索 API 来获取商店 ID,以用于设置队列。
