我发现解决方案可能会帮助别人，我应该使用 MPMusicPlayerStoreQueueDescriptor
i found the solution maybe will help someone else , i should use MPMusicPlayerStoreQueueDescriptor
func playByStoreID( storeIds:[String] )
{
DispatchQueue.main.async {
//Prepare before play ios 10.1 and above
if #available(iOS 10.1, *)
{
var ids:[String] = []
for i in self.queue
{
ids.append(String(i.epf_song_id))
}
let descriptor:MPMusicPlayerStoreQueueDescriptor = MPMusicPlayerStoreQueueDescriptor(storeIDs: ids)
descriptor.startItemID = storeIds[0]
self.applicationMusicPlayer.setQueue(with: descriptor)
self.applicationMusicPlayer.prepareToPlay { (error) in
//Wait 5 seconds
if (error != nil)
{
let errorCode:Int = (error! as NSError).code
print("[MUSIC PLAYER] Error (String(describing: error))")
if errorCode == 4 && self.currectPlaying.failed == 0
{
print("[MUSIC PLAYER] Error Load track will play again after 5 seconds")
self.applicationMusicPlayer.stop()
self.currectPlaying.failed = 1
DispatchQueue.main.asyncAfter(deadline: .now() 5 , execute: {
self.play_from_apple( false )
})
}else
{
//Inform player to play with another streamer
self.fullFailure()
print("[MUSIC PLAYER] Error preparing : (String(describing: error))")
}
return
}else
{
self.applicationMusicPlayer.play()
self.playedBy = .apple
}
}
}else
//Play directly ios below version 10.1
{
self.applicationMusicPlayer.setQueue(with: storeIds)
self.applicationMusicPlayer.play()
}
}
}
