iPhone SDK:你如何播放视频的视图里面? 而不是全屏(iPhone SDK:How do

2019-06-18 10:02发布

我尝试播放视频里面UIView ,所以我的第一步是添加一个类为该视图,并开始使用此代码播放电影吧:

- (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];
}

但这种使用它自己的类中此方法时只是崩溃的应用程序,但其他地方的罚款。 有谁知道怎么玩一个视图中的视频? 并避免它成为全屏幕?

Answer 1:

由于3.2 SDK,您可以访问的视图属性MPMoviePlayerController ,修改它的框架,并将其添加到您的视图层次。

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

Answer 2:

最好的办法是使用图层insted的观点:

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];

不要忘了添加框架:

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


Answer 3:

看你的代码,你需要设置视频播放器控制器的视图的框架,并且还添加了视频播放器控制器的视图到您的视图。 另外,不要忘记MediaPlayer.framework添加到您的目标。

下面是一些示例代码:

#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

迅速

这是一个自包含的项目,这样就可以看到在上下文中的一切。

布局

创建像一个下面的一个布局UIViewUIButton 。 该UIView将是我们将发挥我们的视频容器。

视频添加到项目

如果你需要一个样本视频操练,你可以得到一个从sample-videos.com 。 我使用的是在这个例子中的MP4格式视频。 拖动和视频文件拖放到你的项目。 我还必须明确将其添加到捆绑资源(去构建阶段>复制包资源 ,看到这个答案更多)。

下面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

  • 如果你将要接通和断开不同的视频,您可以使用AVPlayerItem
  • 如果你只使用AVFoundationAVPlayer ,那么你必须建立全部由您自己控制。 如果你想全屏幕视频播放,您可以使用AVPlayerViewController 。 您将需要导入AVKit了点。 它配备了用于暂停全套的控制,快进,快退,停止等在这里和这里有一些视频教程。
  • MPMoviePlayerController ,你可以在其他的答案已经看到了已被弃用。

结果

该项目应该是现在这个样子。



Answer 5:

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

[self presentMoviePlayerViewControllerAnimated:playerv];


Answer 6:

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;
  }


Answer 7:

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()
}


Answer 8:

使用下面的方法。

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];
}


Answer 9:

您无法播放视频的视图中。 它要播放全屏。
