不可能停止AVPlayer

不可能停止AVPlayer

如果声明

player

为可选变量，则可以将播放器设置

nil

为取消分配它。

愚蠢的例子，但它显示了会发生什么：

import UIKitimport AVFoundationclass ViewController: UIViewController {    @IBOutlet weak var btnPlay: UIButton!    var player:AVPlayer?    override func viewDidLoad() {        super.viewDidLoad()    }    @IBAction func btnPress(sender: AnyObject) {        if (btnPlay.titleLabel?.text == "Play") { initPlayer() btnPlay.setTitle("Stop", forState: UIControlState.Normal)        } else { stopPlayer() btnPlay.setTitle("Play", forState: UIControlState.Normal)        }    }    func initPlayer()  {        if let play = player { print("playing") play.play()        } else { print("player allocated") player = AVPlayer(URL: NSURL(string: "http://streaming.radio.rtl.fr/rtl-1-48-192")!) print("playing") player!.play()        }    }    func stopPlayer() {        if let play = player { print("stopped") play.pause() player = nil print("player deallocated")        } else { print("player was already deallocated")        }    }}
