ios - iPhone SDK：如何在视图中播放视频？而不是全屏

Question

我正在尝试在 a 中播放视频UIView，所以我的第一步是为该视图添加一个类并使用以下代码开始在其中播放电影：

- (IBAction)movie:(id)sender{
    NSBundle *bundle = [NSBundle mainBundle];
        NSString *moviePath = [bundle pathForResource:@"Movie" ofType:@"m4v"];
    NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain];
    MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
    theMovie.scalingMode = MPMovieScalingModeAspectFill;
    [theMovie play];
}

但这只会在应用程序自己的类中使用此方法时崩溃，但在其他地方很好。有谁知道如何在视图中播放视频？并避免它是全屏的？

从 3.2 SDK 开始，您可以访问的 view 属性MPMoviePlayerController，修改其框架并将其添加到您的视图层次结构中。

MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:url]];
player.view.frame = CGRectMake(184, 200, 400, 300);
[self.view addSubview:player.view];
[player play];

最好的方法是使用嵌入视图的图层：

AVPlayer *player = [AVPlayer playerWithURL:[NSURL url...]]; // 

AVPlayerLayer *layer = [AVPlayerLayer layer];

[layer setPlayer:player];
[layer setFrame:CGRectMake(10, 10, 300, 200)];
[layer setBackgroundColor:[UIColor redColor].CGColor];
[layer setVideoGravity:AVLayerVideoGravityResizeAspectFill];

[self.view.layer addSublayer:layer];

[player play];

不要忘记添加框架：

#import <QuartzCore/QuartzCore.h>
#import "AVFoundation/AVFoundation.h"

这是一个独立的项目，因此您可以在上下文中查看所有内容。

布局

使用 aUIView和 a创建如下布局UIButton。将UIView是我们将在其中播放视频的容器。

将视频添加到项目中

如果您需要一个示例视频来练习，您可以从sample-videos.com获得一个。在此示例中，我使用的是 mp4 格式的视频。将视频文件拖放到您的项目中。我还必须将它显式添加到捆绑资源中（转到Build Phases > Copy Bundle Resources，有关更多信息，请参阅此答案）。

代码

这是该项目的完整代码。

import UIKit
import AVFoundation

class ViewController: UIViewController {

    var player: AVPlayer?

    @IBOutlet weak var videoViewContainer: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()
        initializeVideoPlayerWithVideo()
    }

    func initializeVideoPlayerWithVideo() {

        // get the path string for the video from assets
        let videoString:String? = Bundle.main.path(forResource: "SampleVideo_360x240_1mb", ofType: "mp4")
        guard let unwrappedVideoPath = videoString else {return}

        // convert the path string to a url
        let videoUrl = URL(fileURLWithPath: unwrappedVideoPath)

        // initialize the video player with the url
        self.player = AVPlayer(url: videoUrl)

        // create a video layer for the player
        let layer: AVPlayerLayer = AVPlayerLayer(player: player)

        // make the layer the same size as the container view
        layer.frame = videoViewContainer.bounds

        // make the video fill the layer as much as possible while keeping its aspect size
        layer.videoGravity = AVLayerVideoGravity.resizeAspectFill

        // add the layer to the container view
        videoViewContainer.layer.addSublayer(layer)
    }

    @IBAction func playVideoButtonTapped(_ sender: UIButton) {
        // play the video if the player is initialized
        player?.play()
    }
}

笔记

如果您要切换进出不同的视频，您可以使用AVPlayerItem.
如果您只使用AVFoundationand AVPlayer，那么您必须构建自己的所有控件。如果要全屏播放视频，可以使用AVPlayerViewController. 您需要为此导入AVKit。它带有一整套用于暂停、快进、倒带、停止等的控件。这里和这里有一些视频教程。
MPMoviePlayerController您可能在其他答案中看到的已弃用。

结果

该项目现在应该是这样的。

查看您的代码，您需要设置电影播放器控制器视图的框架，并将电影播放器控制器的视图添加到您的视图中。另外，不要忘记将MediaPlayer.framework添加到您的目标中。

这是一些示例代码：

#import <MediaPlayer/MediaPlayer.h>

@interface ViewController () {
    MPMoviePlayerController *moviePlayerController;
}

@property (weak, nonatomic) IBOutlet UIView *movieView; // this should point to a view where the movie will play

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    // Instantiate a movie player controller and add it to your view
    NSString *moviePath = [[NSBundle mainBundle] pathForResource:@"foo" ofType:@"mov"];
    NSURL *movieURL = [NSURL fileURLWithPath:moviePath];    
    moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
    [moviePlayerController.view setFrame:self.movieView.bounds];  // player's frame must match parent's
    [self.movieView addSubview:moviePlayerController.view];

    // Configure the movie player controller
    moviePlayerController.controlStyle = MPMovieControlStyleNone;        
    [moviePlayerController prepareToPlay];
}

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    // Start the movie
    [moviePlayerController play];
}

@end

NSString * pathv = [[NSBundle mainBundle] pathForResource:@"vfile" ofType:@"mov"];
playerv = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:pathv]];

[self presentMoviePlayerViewControllerAnimated:playerv];

NSURL *url = [NSURL URLWithString:[exreciesDescription objectForKey:@"exercise_url"]];
moviePlayer =[[MPMoviePlayerController alloc] initWithContentURL: url];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(doneButtonClicked) name:MPMoviePlayerWillExitFullscreenNotification object:nil];
[[moviePlayer view] setFrame: [self.view bounds]];  // frame must match parent view
[self.view addSubview: [moviePlayer view]];
[moviePlayer play];

-(void)playMediaFinished:(NSNotification*)theNotification 
{
    moviePlayer=[theNotification object];
    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:MPMoviePlayerPlaybackDidFinishNotification
                                                  object:moviePlayer];


    [moviePlayer.view removeFromSuperview];
}

-(void)doneButtonClicked
  {
         [moviePlayer stop];
        [moviePlayer.view removeFromSuperview];
         [self.navigationController popViewControllerAnimated:YES];//no need this if you are      opening the player in same screen;
  }

斯威夫特版本：

import AVFoundation

func playVideo(url: URL) {

    let player = AVPlayer(url: url)

    let layer: AVPlayerLayer = AVPlayerLayer(player: player)
    layer.backgroundColor = UIColor.white.cgColor
    layer.frame = CGRect(x: 0, y: 0, width: 300, height: 300)
    layer.videoGravity = .resizeAspectFill
    self.view.layer.addSublayer(layer)

    player.play()
}

使用以下方法。

self.imageView_VedioContainer是你的容器视图AVPlayer。

- (void)playMedia:(UITapGestureRecognizer *)tapGesture
{
    playerViewController = [[AVPlayerViewController alloc] init];

    playerViewController.player = [AVPlayer playerWithURL:[[NSBundle mainBundle]
                                                 URLForResource:@"VID"
                                                         withExtension:@"3gp"]];
    [playerViewController.player play];
    playerViewController.showsPlaybackControls =YES;
    playerViewController.view.frame=self.imageView_VedioContainer.bounds;
    [playerViewController.view setAutoresizingMask:UIViewAutoresizingNone];// you can comment this line 
    [self.imageView_VedioContainer addSubview: playerViewController.view];
}

您不能在视图内播放视频。必须全屏播放。
