更新：最终我决定制作自己的控件以获得更好的自定义性。这样做更难，但是值得花费时间。请参考苹果的示例代码，它涉及到实现画中画，同时也包括制作自定义控件：https://developer.apple.com/library/prerelease/ios/samplecode/AVFoundationPiPPlayer/Introduction/Intro.html
更新：当点击时，AVPlayerViewController只会触发touchesBegan事件，而不会触发touchesEnded事件。但是这已经足够显示控件了。
首先，您需要隐藏控件。将此代码放在您展示AVPlayerViewController之前。
YourAVPlayerViewController.showsPlaybackControls = false
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
self.showsPlaybackControls = true
super.touchesBegan(touches, withEvent: event)
}
旧解决方案：
我刚刚解决了这个问题。主要思路是在AVPlayerViewController上面放置一个UIView来接收点击手势，并在不需要时隐藏该UIView。
以下是代码：
import AVKit
import UIKit
// Create a custom AVPlayerViewController
@available(iOS 8.0, *)
final class CustomAVPlayerViewController: AVPlayerViewController {
// Create a UIView to put on top of all
lazy var topView = UIView(frame: CGRectMake(0, 0, width, height))
override func viewDidLoad() {
super.viewDidLoad()
// For sure, set it to clearcolor
// (DON'T set alpha = 0 because it will stop receiving user interaction)
topView.backgroundColor = UIColor.clearColor()
// Add it to the view of AVPlayerViewController
self.view.addSubview(topView)
// Bring it to front
self.view.bringSubviewToFront(topView)
// Add a tap gesture recognizer
topView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: "handleTap"))
}
// Handle the tap
func handleTap() {
// Show the control
self.showsPlaybackControls = true
// Hide the topView. You can unhide it when needed later.
self.topView.hidden = true
}
}
当你需要隐藏控件时，请执行以下操作：
var AVViewController = CustomAVPlayerViewController()
...
// Hide controls
AVViewController.showsPlaybackControls = false
// Show topView
AVViewController.topView.hidden = false
我认为我已经使用了动态手势识别器关系来解决这个问题，该解决方案避免了自定义控件（以保持一致性），仅使用公共API，并且不对 AVPlayerViewController 进行子类化（正如其他答案中指出的那样，这是明确禁止的）。
具体实现方法如下：
制作一个容器视图控制器来嵌入 AVPlayerViewController。（无论控件如何，这都很有用，因为你需要将播放逻辑放在某个地方。）
初始时将 showsPlaybackControls 设置为 false。
添加一个 UITapGestureRecognizer 来识别初始轻按操作。
在手势识别器的动作方法中，将 showsPlaybackControls 设置为 true。
到目前为止，它可以工作，但控件会立即消失。要修复这个问题，将自己设置为手势识别器的代理，实现 gestureRecognizer:shouldBeRequiredToFailByGestureRecognizer: 方法，并返回对于任何其他单击手势识别器都应该返回 true。
这里是用 Swift 实现的实际代码；请查看 andreyvit/ModalMoviePlayerViewController 存储库中的最新代码：
import UIKit
import AVKit
import AVFoundation
public class ModalMoviePlayerViewController: UIViewController {
private let fileName: String
private let loop: Bool
private var item: AVPlayerItem!
private var player: AVPlayer!
internal private(set) var playerVC: AVPlayerViewController!
private var waitingToAutostart = true
public init(fileName: String, loop: Bool = true) {
self.fileName = fileName
self.loop = loop
super.init(nibName: nil, bundle: nil)
}
public required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
public override func viewDidLoad() {
super.viewDidLoad()
let url = NSBundle.mainBundle().URLForResource(fileName, withExtension: nil)!
item = AVPlayerItem(URL: url)
player = AVPlayer(playerItem: item)
player.actionAtItemEnd = .None
player.addObserver(self, forKeyPath: "status", options: [], context: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(ModalMoviePlayerViewController.didPlayToEndTime), name: AVPlayerItemDidPlayToEndTimeNotification, object: item)
playerVC = AVPlayerViewController()
playerVC.player = player
playerVC.videoGravity = AVLayerVideoGravityResizeAspectFill
playerVC.showsPlaybackControls = false
let playerView = playerVC.view
addChildViewController(playerVC)
view.addSubview(playerView)
playerView.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
playerView.frame = view.bounds
playerVC.didMoveToParentViewController(self)
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(ModalMoviePlayerViewController.handleTap))
tapGesture.delegate = self
view.addGestureRecognizer(tapGesture)
}
deinit {
player.pause()
player.removeObserver(self, forKeyPath: "status")
NSNotificationCenter.defaultCenter().removeObserver(self)
}
func togglePlayPause() {
if isPlaying {
pause()
} else {
play()
}
}
func restart() {
seekToStart()
play()
}
func play() {
if player.status == .ReadyToPlay {
player.play()
} else {
waitingToAutostart = true
}
}
func pause() {
player.pause()
waitingToAutostart = false
}
var isPlaying: Bool {
return (player.rate > 1 - 1e-6) || waitingToAutostart
}
private func performStateTransitions() {
if waitingToAutostart && player.status == .ReadyToPlay {
player.play()
}
}
public override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer<Void>) {
performStateTransitions()
}
@objc func didPlayToEndTime() {
if isPlaying && loop {
seekToStart()
}
}
private func seekToStart() {
player.seekToTime(CMTimeMake(0, 10))
}
public override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
if !playerVC.showsPlaybackControls {
playerVC.showsPlaybackControls = true
}
super.touchesBegan(touches, withEvent: event)
}
}
extension ModalMoviePlayerViewController: UIGestureRecognizerDelegate {
@IBAction func handleTap(sender: UIGestureRecognizer) {
if !playerVC.showsPlaybackControls {
playerVC.showsPlaybackControls = true
}
}
/// Prevents delivery of touch gestures to AVPlayerViewController's gesture recognizer,
/// which would cause controls to hide immediately after being shown.
///
/// `-[AVPlayerViewController _handleSingleTapGesture] goes like this:
///
/// if self._showsPlaybackControlsView() {
/// _hidePlaybackControlsViewIfPossibleUntilFurtherUserInteraction()
/// } else {
/// _showPlaybackControlsViewIfNeededAndHideIfPossibleAfterDelayIfPlaying()
/// }
public func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldBeRequiredToFailByGestureRecognizer otherGestureRecognizer: UIGestureRecognizer) -> Bool {
if !playerVC.showsPlaybackControls {
// print("\nshouldBeRequiredToFailByGestureRecognizer? \(otherGestureRecognizer)")
if let tapGesture = otherGestureRecognizer as? UITapGestureRecognizer {
if tapGesture.numberOfTouchesRequired == 1 {
return true
}
}
}
return false
}
}
thegathering的回答很好。我建议重写touchesCancelled方法，这样控件就不会再显示然后再隐藏。
override public func touchesCancelled(touches: Set<UITouch>?, withEvent event: UIEvent?) {
super.touchesCancelled(touches, withEvent: event)
// toggle the player controls on if they were set to off
if !self.showsPlaybackControls {
self.showsPlaybackControls = true
}
}
myController.showsPlaybackControls = false，并用一个按钮或手势识别器覆盖整个播放器视图。我将其嵌入到另一个控制器的另一个视图中，以使其简单且不覆盖播放器控制器。然后，技巧是在点击一次按钮后隐藏它，因为播放器控制器此后将跟踪点击以显示/隐藏控件。@IBAction func enableControls(button:UIButton)
{
controller?.showsPlaybackControls = true
button.isHidden = true //The button is only needed once, then the player takes over.
}
设置showsPlaybackControls = false，然后精确地添加以下代码：
///Address insane Apple long-standing issue that you can't "launch it
///with no controls". There's no perfect solution.
var _firstTap = true
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
if _firstTap {
showsPlaybackControls = true
_firstTap = false
return
}
super.touchesBegan(touches, with: event)
}
showsPlaybackControls。 - hbk
