在Swift中以MPMediaItemCollection的特定索引播放歌曲

问题描述

我尝试用Swift制作自己的Musicplayer.我需要跳到我的MPMediaItemCollection的特定歌曲/索引并开始播放它，但是我只能找到诸如skipToNextItem()和skipToPreviousItem()之类的方法.除了循环，还有其他方法吗?

I try to make my own Musicplayer with Swift. I need to jump to a specific song/index of my MPMediaItemCollection and start to play it but i can only find methods like skipToNextItem() and skipToPreviousItem(). Is there any other way to do that than with a loop?

let player = MPMusicPlayerController.systemMusicPlayer()
player.setQueueWithItemCollection(mediaCollection)
player.play()

推荐答案

根据文档，我们使用nowPlayingItem属性.

因此，听起来您应该停止或暂停播放器，设置nowPlayingItem，然后再次调用play.

So, it sounds like you should stop or pause the player, set the nowPlayingItem, and then call play again.

player.nowPlayingItem = mediaCollection.items[selectedIndex]
player.play()
