按钮触发视频打开和播放

Question

我对编码很陌生，没有经验。 我找到了一种播放视频的方法，但它会自动播放/自动打开。我需要视频仅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()
    }
}

您可以简单地将其放在您的 ViewController 中的任何位置，只要它不在另一个函数中。

然后将其与情节提要中的按钮连接：

这是一个按钮的外观，这个例子是从 Firebase 中提取一部电影，但除此之外，它的外观是这样的

@IBAction func playV(sender: UIButton) {
   
        

     
          
            let amovieUrl:NSURL? = NSURL(string: "https://firebasestorage.googleapis.com/v0/b/messenger-test-d225b.appspot.com/o/test%2FTestVideo.mov?alt=media&token=bd4ccba3-b446-43bc-809e-b1152aa3c2ff")
            if let aurl = amovieUrl {
                self.avPlayer = AVPlayer(url: aurl as URL)
            self.avPlayerViewController.player = self.avPlayer
        
self.present(self.avPlayerViewController, animated: true) { () -> Void in
        self.avPlayerViewController.player?.play()

   
}

}

}

1. 创建操作连接as explained here。
2. 将viewDidAppear 中的代码移至您在步骤 1 中创建的操作。
3. 利润。

另外，您不需要 viewDidLoad 和 didReceiveMemoryWarning 的默认实现：

import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController {

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

@IBAction func yourActionForButton(sender: UIButton) {
    // Your code.
}
