播放 mp4 文件然后切换到视图控制器，文件播放正常但无法弄清楚切换到另一个视图的代码

Question

import AVFoundation
import UIKit
import AVKit

class Class1: AVPlayerViewController, AVPlayerViewControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    func playVideo() {

        if let path = NSBundle.mainBundle().pathForResource("output_aV7EL0", ofType: "mp4") {
            let url = NSURL(fileURLWithPath: path)
            player = AVPlayer(URL: url)
            player?.play()
        }
        else {
            print("Oops, something wrong when playing video.mp4")
        }
    }

    override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)
        playVideo()
    }

    func AVPlayerDidFinishPlaying(player: AVAudioPlayer!, successfully flag: Bool) {
        if player.playing {
            player.stop()
        }
    }
}

我已经获得了要播放的 mp4 文件，但我需要在视频播放完毕后切换到不同的视图，我该怎么做？如有任何提示，我们将不胜感激。

func playVideo() {

    if let path = NSBundle.mainBundle().pathForResource("output_aV7EL0", ofType: "mp4") {
        let url = NSURL(fileURLWithPath: path)
        player = AVPlayer(URL: url)
        player?.play()
        self.dismissViewControllerAnimated(true, completion: nil)
        self.presentViewController(viewcontrollerToPresent: GameViewController1, animated: true, completion: nil)
    }

你所说的 "switching" 是什么意思？能具体点吗？

如果您想关闭页面，请执行以下操作：

如果它在导航控制器中：

self.navigationController?.popViewControllerAnimated(true)

如果出现：

self.dismissViewControllerAnimated(true, completion: nil)

如果你想呈现另一个视图控制器：

如果它在导航控制器中：

self.navigationController?.pushViewController(yourViewController, animated: true)

如果要模态呈现：

self.presentViewController(vc, animated: true, completion: nil)
