MPMoviePlayerController 行为不正常答案

【问题描述】：

我正在使用 MPMoviePlayerController 播放一个小视频作为我的应用的介绍视频。我已经使用了以下代码，并且效果很好。但是视频一直在播放。结束并再次重新启动。即使我单击完成按钮，它也不会删除超级视图。我还希望我的状态栏可见，并且我保持半透明仍然没有结果。我在谷歌上搜索和堆栈溢出但仍然没有帮助。任何帮助都会非常显着。

我在viewDidAppear中调用了[self playMovie]方法

-(void)playMovie
{
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"avc_intro" ofType:@"mp4"]];
moviePlayer =  [[MPMoviePlayerController alloc]
                initWithContentURL:url];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:moviePlayer];
         name:MPMoviePlayerWillExitFullscreenNotification
                                          object:moviePlayer];

moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.shouldAutoplay = YES;
[self.view addSubview:moviePlayer.view];
[moviePlayer setFullscreen:YES animated:YES];
}

- (void) moviePlayBackDidFinish:(NSNotification*)notification
{
MPMoviePlayerController *videoplayer = [notification object];
[[NSNotificationCenter defaultCenter]
 removeObserver:self
 name:MPMoviePlayerPlaybackDidFinishNotification
 object:videoplayer];

if ([videoplayer
     respondsToSelector:@selector(setFullscreen:animated:)])
{
    [videoplayer.view removeFromSuperview];
}
}

【解决方案1】：

更好地使用this. MPMoviePlayerController 在 iOS 9 中被正式弃用。

【讨论】：

【解决方案2】：

从viewDidload 调用[self playMovie]，因为删除MPMoviePlayerController 时再次调用viewDidAppear，因此它将再次启动。

更新：

您应该呈现MPMusicPlayerController，而不是将其视图添加到超级视图并在完成时关闭它

希望这会有所帮助:)

如果我在 viewDidLoad 中调用它就不会播放

【解决方案3】：

使用 AVPlayerViewController 我的代码如下，

objective-C 代码：声明AVPlayerViewController *playerViewController;

    playerViewController = [[AVPlayerViewController alloc]init];
    playerViewController.view.frame = videoView.bounds;
    [playerViewController.view setAutoresizingMask:(UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight)];
    playerViewController.player = [AVPlayer playerWithURL:[NSURL URLWithString:viewModel.videoUrl]];
    [videoView addSubview:playerViewController.view];
    [playerViewController.player play];
    playerViewController.player.actionAtItemEnd = AVPlayerActionAtItemEndNone;

不要忘记下面给出的框架，

#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#import <AVKit/AVKit.h>
#import <MediaPlayer/MediaPlayer.h>

快速代码：

        let type : String! = "mp4"
        let targetURL : String? = NSBundle.mainBundle().pathForResource("Official Apple MacBook Air Video   YouTube", ofType: "mp4")

        let videoURL = NSURL(fileURLWithPath:targetURL!)


        let player = AVPlayer(URL: videoURL)
        let playerController = AVPlayerViewController()

        playerController.player = player
        self.addChildViewController(playerController)
        self.playView.addSubview(playerController.view)
        playerController.view.frame = playView.bounds

        player.play()

不要忘记下面给出的框架，

import UIKit
import AVKit
import AVFoundation
import MediaPlayer

它对我有用，希望它有帮助
