iOS UiView中的Swift Swift Player如何运行 [英] IOS swift avplayer inside UiView how can I make it work
问题描述
我是刚开始使用AVPlayer for IOS swift并使其正常工作.但是,我希望视频现在可以在UIView中播放,默认情况下,视频占据了整个页面.我一直在尝试一些事情,但是我的代码在这里没有任何作用.我在该页面上还有其他内容,这就是为什么我希望UIView内的avplayer被称为 newView 的原因,并且当我将代码放在下面时,它给了我一个错误.我一直在关注这个示例 UIView图层中的AVPlayerLayer位置
I am new to using the AVPlayer for IOS swift and got it working correctly. However I would like the video to play inside a UIView right now the video takes up the whole page as default . I have been trying a few things and nothing works here is my code . I have other content on that page that is why I would like the avplayer inside the UIVIEW which is called newView and when I put the code below it gives me an error. I have been following this example AVPlayerLayer Position in UIView Layer
import UIKit
import AVFoundation
import WebKit
import AVKit
class ExampleTable: UIViewController {
@IBOutlet weak var newView: UIView!
let avPlayerViewController = CustomAVPLayerC()
var playerView: AVPlayer?
var AVLayer: AVPlayerLayer?
override func viewDidAppear(_ animated: Bool) {
let movieURL:NSURL? = NSURL(string: "my url")
playerView = AVPlayer(url: movieURL! as URL)
avPlayerViewController.player = playerView
playerView?.isMuted = true
avPlayerViewController.view.frame = newView.frame
newView.addSubview(avPlayerViewController.view)
addChildViewController(avPlayerViewController)
self.present(self.avPlayerViewController, animated: true) {
self.avPlayerViewController.player?.play()
}
}
override func viewDidLoad() {
super.viewDidLoad()
}
}
但是,当我执行上面的代码时,会出现此错误
However when I do the code above I get this error

推荐答案
之所以收到错误消息,是因为您试图呈现与刚刚添加为子视图控制器的CustomAVPlayerC
实例相同的实例.您无需提供VC,请尝试以下代码,这是一种更简洁的方法:
You are getting the error message because you are trying to present the same instance of your CustomAVPlayerC
that you just added as a child view controller. You don't need to present the VC, try this code which is a little cleaner approach:
@IBOutlet weak var newView: UIView!
let avPlayerViewController = CustomAVPlayerC()
var playerView: AVPlayer?
override func viewDidLoad() {
super.viewDidLoad()
guard let movieURL = URL(string: "my url")
else { return }
playerView = AVPlayer(url: movieURL)
avPlayerViewController.player = playerView
avPlayerViewController.view.frame = newView.bounds
self.addChildViewController(avPlayerViewController)
newView.addSubview(avPlayerViewController.view)
avPlayerViewController.didMove(toParentViewController: self)
}
我建议阅读实现容器视图控制器的苹果文档"获得处理这样设置的容器视图的最佳实践.
I would recommend going over Apple's documentation on "Implementing a Container View Controller" for best practices in dealing with a container view set up like this.
