ios - 按钮触发视频打开播放

Question

我对编码很陌生，没有任何经验。我找到了一种播放视频的方法，但它会自动播放/自动打开。我需要视频只在按下按钮时打开和播放。请有人帮我调整我的代码来做到这一点。

这是我当前的代码:

import UIKit
import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController {


    var playerviewcontroller = AVPlayerViewController()
    var playerview = AVPlayer ()

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

    }

    override func viewDidAppear(animated: Bool) {
        var fileURL = NSURL(fileURLWithPath:"/Users/MorganEvans/Documents/Apps/Warm Up/Video View/Video View/ViewController.swift")
        playerview = AVPlayer(URL: fileURL)

        playerviewcontroller.player = playerview

        self.presentViewController(playerviewcontroller, animated: true){

            self.playerviewcontroller.player?.play()
        }


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

}

Answer 1

试试这个:

@IBAction func playMusic(sender: AnyObject) {
    var fileURL = NSURL(fileURLWithPath:"/Users/MorganEvans/Documents/Apps/Warm Up/Video View/Video View/ViewController.swift")
    playerview = AVPlayer(URL: fileURL)

    playerviewcontroller.player = playerview

    self.presentViewController(playerviewcontroller, animated: true){

        self.playerviewcontroller.player?.play()
    }
}

只要不在另一个函数中，您可以将它简单地放在 ViewController 中的任何位置。

然后将它与 Storyboard中的按钮连接起来:
