Question

我有一些代码可以让我在点击UIButton时播放本地文件。但我想要的是在3个不同的UIButton上播放多个文件，因为我有3个视频文件，我想附加到我的应用程序。

这是当前的代码：

import UIKit
import AVFoundation
import AVKit

class ViewController: UIViewController {

    var playerController = AVPlayerViewController()
    var player:AVPlayer?


    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        let videoString:String? = Bundle.main.path(forResource: "Video", ofType: ".mp4")

        if let url = videoString {

            let videoURL = NSURL(fileURLWithPath: url)

            self.player = AVPlayer(url: videoURL as URL)
            self.playerController.player = self.player



        }


    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func PlayVideo(_ sender: AnyObject) {

        self.present(self.playerController, animated: true, completion: {

            self.playerController.player?.play()

        })

    }


}

您可以在按钮点击功能中为不同的视频文件创建网址

@IBAction func Button1Click(_ sender: AnyObject) {
    let videoString:String? = Bundle.main.path(forResource: "Video1", ofType: ".mp4")

    if let url = videoString {
        let videoURL = NSURL(fileURLWithPath: url)
        self.player = AVPlayer(url: videoURL as URL)
        self.playerController.player = self.player
    }

    self.present(self.playerController, animated: true, completion: {
        self.playerController.player?.play()

    })

}

@IBAction func Button2Click(_ sender: AnyObject) {
    let videoString:String? = Bundle.main.path(forResource: "Video2", ofType: ".mp4")

    if let url = videoString {
        let videoURL = NSURL(fileURLWithPath: url)
        self.player = AVPlayer(url: videoURL as URL)
        self.playerController.player = self.player
    }

    self.present(self.playerController, animated: true, completion: {
        self.playerController.player?.play()

    })

}

@IBAction func Button3Click(_ sender: AnyObject) {
    let videoString:String? = Bundle.main.path(forResource: "Video3", ofType: ".mp4")

    if let url = videoString {
        let videoURL = NSURL(fileURLWithPath: url)
        self.player = AVPlayer(url: videoURL as URL)
        self.playerController.player = self.player
    }

    self.present(self.playerController, animated: true, completion: {
        self.playerController.player?.play()

    })

}
