我有一个场景,当我播放单个音频文件并移动到控制中心时,它工作正常,但如果返回 View Controller (在那里调用player.pause())并返回并尝试其他文件,它可以工作在同一 Controller 上,但在控制中心,上一个文件也同时播放。
可能是因为 AVPlayer 对象,我的处理程序调用了多次。
MPRemoteCommandCenter.shared().playCommand.addTarget { (playEvent) -> MPRemoteCommandHandlerStatus in
let currentItem = self.player.currentItem
self.player.replaceCurrentItem(with: currentItem)
if self.player.isPlaying {
self.player.pause()
}else{
self.player.play()
}
self.updateInfo()
self.btnAudioPlay.setImage(#imageLiteral(resourceName: "pause"), for: .normal)
return .success
}
MPRemoteCommandCenter.shared().pauseCommand.addTarget { (pauseEvent) -> MPRemoteCommandHandlerStatus in
if self.player.isPlaying {
self.player.pause()
}else{
self.player.play()
}
self.updateInfo()
self.btnAudioPlay.setImage(#imageLiteral(resourceName: "play"), for: .normal)
return .success
}
func updateInfo() {
let image = UIApplication.shared.icon!
let mediaArtwork = MPMediaItemArtwork(boundsSize: image.size) { (size: CGSize) -> UIImage in
return image
}
let nowPlayingInfo: [String: Any] = [
MPMediaItemPropertyAlbumTitle: self.subTilteForAudioPlayer,
MPMediaItemPropertyTitle: self.titleForAudioPlayer,
MPMediaItemPropertyArtwork: mediaArtwork,
MPMediaItemPropertyPlaybackDuration: Float(CMTimeGetSeconds((player.currentItem?.asset.duration)!)) ,
MPNowPlayingInfoPropertyElapsedPlaybackTime: Float(CMTimeGetSeconds(player.currentTime()))
]
MPNowPlayingInfoCenter.default().nowPlayingInfo = nowPlayingInfo
}
最佳答案
音频播放器每次都会初始化,它出现在同一屏幕上,因此通知中心会播放多个声音。
player = nil
上面的代码对我有用。
关于ios - 通知控制中心同时播放多个音频,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/50637406/
