如何使用 Swift 播放本地视频?

问题描述

我有一个简短的 mp4 视频文件，我已将其添加到我当前的 Xcode6 Beta 项目中.

I have a short mp4 video file that I've added to my current Xcode6 Beta project.

我想在我的应用中播放视频.

经过数小时的搜索，我找不到任何远程帮助.有没有办法用 Swift 来完成这个，或者你必须使用 Objective-C?我可以指出正确的方向吗?我不可能是唯一一个想知道这一点的人.

After hours searching, I can't find anything remotely helpful. Is there a way to accomplish this with Swift or do you have to use Objective-C?Can I get pointed in the right direction? I can't be the only one wondering this.

推荐答案

当然可以使用 Swift！

Sure you can use Swift!

将视频(我们称之为 video.m4v)添加到您的 Xcode 项目

Add the video (lets call it video.m4v) to your Xcode project

打开Project Navigator +

然后选择你的项目根目录 > 你的目标 > Build Phases > Copy Bundle Resources.

Then select your project root > your Target > Build Phases > Copy Bundle Resources.

您的视频必须在这里.如果不是，那么您应该使用加号按钮添加它

Your video MUST be here. If it's not, then you should add it using the plus button

打开您的视图控制器并编写此代码.

Open your View Controller and write this code.

import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController {

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

    private func playVideo() {
        guard let path = Bundle.main.path(forResource: "video", ofType:"m4v") else {
            debugPrint("video.m4v not found")
            return
        }
        let player = AVPlayer(url: URL(fileURLWithPath: path))
        let playerController = AVPlayerViewController()
        playerController.player = player
        present(playerController, animated: true) {
            player.play()
        }
    }
}
