我想在我的应用中播放视频,我使用avplayer
没有问题,但在结束视频后,应用程序崩溃了,我收到此错误:
无法识别的选择器发送到实例0x7f950bf6d1a0 2015-10-09 14:42:42.769拼车[47925:1543415] ***由于终止应用程序 未捕获的异常'NSInvalidArgumentException',原因: ' - [Carpooling.ViewController playerItemDidReachEnd:]:无法识别 选择器发送到实例0x7f950bf6d1a0'
我的错误是什么?
lazy var playerLayer:AVPlayerLayer = {
let player = AVPlayer(URL: NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("BWWalkthrough", ofType: "mp4")!))
player.muted = true
player.allowsExternalPlayback = false
player.appliesMediaSelectionCriteriaAutomatically = false
var error:NSError?
// This is needed so it would not cut off users audio (if listening to music etc.
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryAmbient)
} catch var error1 as NSError {
error = error1
} catch {
fatalError()
}
if error != nil {
print(error)
}
var playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.view.frame
playerLayer.videoGravity = "AVLayerVideoGravityResizeAspectFill"
playerLayer.backgroundColor = UIColor.blackColor().CGColor
player.play()
player.actionAtItemEnd = AVPlayerActionAtItemEnd.None
NSNotificationCenter.defaultCenter().addObserver(self, selector: "playerItemDidReachEnd:",
name: AVPlayerItemDidPlayToEndTimeNotification,
object: player.currentItem)
return playerLayer
}()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.view.layer.addSublayer(self.playerLayer)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}

您正在向NSNotificationCenter
注册观察者,并告知观察者在收到通知后致电playerItemDidReachEnd:
但您的代码未实施playerItemDidReachEnd:
因此代码可以& #39;找到方法并崩溃。

@Bensarz的回答是正确的。你错过了接收方法。
添加以下方法
func playerItemDidReachEnd(playerItem: AVPlayerItem) {
//Do your stuff here
}
