Swift3 MPMoviePlayerViewController的使用,iOS播放视频

痛定思痛。 2022-07-13 06:21 264阅读 0赞

**[iOS][]播放视频文件一般使用 MPMoviePlayerViewController 和 MPMoviePlayerController。MPMoviePlayerViewController里面包含了一个MPMoviePlayerController，如果要在页面中内嵌播放器的话，使用MPMoviePlayerController，如果只需要播放一个视频，那么用MPMoviePlayerViewController也是很方便的。**

**下面是我自己封装的一个调用播放器的方法，用Swift3.0写的**

import UIKit
    import MediaPlayer
    
    final class YSDMediaPlayer: NSObject {
        static let shared = YSDMediaPlayer()
        private override init() {}
        
        func showPlayerWithFile(path: String?, presentedViewController: UIViewController) {
            guard let pa = path else {
                return
            }
            autoreleasepool {
                let movieURL = URL(fileURLWithPath: pa)
                let movieController = MPMoviePlayerViewController(contentURL: movieURL)!
                movieController.moviePlayer.prepareToPlay()
                movieController.moviePlayer.controlStyle = .fullscreen
                movieController.view.backgroundColor = UIColor.black
                movieController.view.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height)
                presentedViewController.present(movieController, animated: true) {
                    NotificationCenter.default.addObserver(forName: NSNotification.Name.MPMoviePlayerPlaybackDidFinish, object: movieController.moviePlayer, queue: OperationQueue.main, using: { (noti) in
                        let theMovie = noti.object as! MPMoviePlayerController
                        NotificationCenter.default.removeObserver(self, name: NSNotification.Name.MPMoviePlayerPlaybackDidFinish, object: theMovie)
                        movieController.dismiss(animated: true, completion: nil)
                    })
                }
            }
        }
    }

moviePlayer.moviewControlMode = MPMovieControlModeDefault

MPMovieControlModeDefault            显示播放/暂停、音量和时间控制

MPMovieControlModeVolumeOnly         只显示音量控制

MPMovieControlModeHidden             没有控制器

moviePlayer.scallingMode = MPMovieScallingModeAspectFit;

你可以使用下列宽高比值：

MPMovieScallingModeNone            不做任何缩放

MPMovieScallingModeAspectFit       适应屏幕大小，保持宽高比

MPMovieScallingModeAspectFill      适应屏幕大小，保持宽高比，可裁剪

MPMovieScallingModeFill            充满屏幕，不保持宽高比

你会观察到以下通知：

MPMoviePlayerContentPreloadDidFinishNotification
