AVPlayer Swift: How do I hide controls and disable landscape view?
提问by D.Bo
since this is my first post, just a few words about me: Usually I design stuff (UI primarily) but I really wanted to take a leap into programming to understand you guys better. So I decided build a small app to get going.
因为这是我的第一篇文章，所以只说几句关于我的：通常我设计东西（主要是 UI），但我真的很想跳入编程领域以更好地理解你们。所以我决定构建一个小应用程序来开始。
So I've been trying to figure this out for hours now – this is my first app project ever so I apologise for my newbyness.
所以我几个小时以来一直在努力解决这个问题——这是我有史以来的第一个应用程序项目，所以我为我的新手道歉。
All I want to do is to hide the controls of AVPlayer and disable landscape view but I just can't figure out where to put showsPlaybackControls = false.
我想要做的就是隐藏 AVPlayer 的控件并禁用横向视图，但我就是不知道将showsPlaybackControls = false.
import UIKit
import AVKit
import AVFoundation
class ViewController: UIViewController {
private var firstAppear = true
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
if firstAppear {
do {
try playVideo()
firstAppear = false
} catch AppError.InvalidResource(let name, let type) {
debugPrint("Could not find resource \(name).\(type)")
} catch {
debugPrint("Generic error")
}
}
}
private func playVideo() throws {
guard let path = NSBundle.mainBundle().pathForResource("video", ofType:"mp4") else {
throw AppError.InvalidResource("video", "m4v")
}
let player = AVPlayer(URL: NSURL(fileURLWithPath: path))
let playerController = AVPlayerViewController()
playerController.player = player
self.presentViewController(playerController, animated: false) {
player.play()
}
}
}
enum AppError : ErrorType {
case InvalidResource(String, String)
}

showsPlaybackControlsis a property of AVPlayerViewController, so you can set it after you create it:
showsPlaybackControls是 的属性AVPlayerViewController，因此您可以在创建它后对其进行设置：
playerController.showsPlaybackControls = false
If you want to allow only landscape, you can subclass AVPlayerViewController, override supportedInterfaceOrientationsand return only landscape, then use that class instead of AVPlayerViewController.
如果您只想允许横向，则可以子类化AVPlayerViewController，覆盖supportedInterfaceOrientations并仅返回横向，然后使用该类而不是AVPlayerViewController.
UPDATE
更新
As mentioned in the comments, if you go to the documentation for AVPlayerViewControlleryou'll find a warning that says:
如评论中所述，如果您查看文档，AVPlayerViewController您会发现一条警告：
Do not subclass AVPlayerViewController. Overriding this class's methods is unsupported and results in undefined behavior.
不要子类化 AVPlayerViewController。不支持覆盖此类的方法并导致未定义的行为。
They probably don't want you to override playback-related methods that could interfere with the behavior, and I would say that overriding onlysupportedInterfaceOrientationsis safe.
他们可能不希望您覆盖可能干扰行为的与播放相关的方法，我会说仅覆盖supportedInterfaceOrientations是安全的。
However, if you want an alternative solution, you can create your own view controller class that overrides supportedInterfaceOrientationsto return landscape only, and place the AVPlayerViewControllerinside that view controller.
但是，如果您需要替代解决方案，您可以创建自己的视图控制器类，该类覆盖supportedInterfaceOrientations以仅返回横向，并将其放置AVPlayerViewController在该视图控制器内部。
