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mp4文件但是我需要在视频播放完毕后切换到不同的视图，我该怎么做？任何提示将不胜感激。

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)
    }

Answer 1

“切换”到另一个视图是什么意思？你能更具体一点吗？

如果要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)

如果要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)

如果您想以模态方式呈现它：

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

播放一个mp4文件，然后切换到视图控制器，文件播放正常，但无法找出切换到另一个视图的代码
