播放远程视频

• 使用AVPlayer 播放远程视频

• ViewController

// ViewController.h
#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

@end

// ViewController.m
#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>

@interface ViewController ()
/** 播放器 */
@property (nonatomic, strong) AVPlayer *player;
/** 图层*/
@property (nonatomic, weak) AVPlayerLayer *layer;
@end

@implementation ViewController

#pragma mark - 懒加载
- (AVPlayerLayer *)layer
{
    if (_layer == nil) {
        // 获取远程视频资源
        // 0.获取远程视频url
        NSURL *remoteURL = [NSURL URLWithString:@"http://v1.mukewang.com/57de8272-38a2-4cae-b734-ac55ab528aa8/L.mp4"];
        // 1.根据url资源创建一个播放器
        self.player = [[AVPlayer alloc] initWithURL:remoteURL];
        // 2.根据播放器对象, 创建一个图层, 展示视频内容给用户看
        _layer = [AVPlayerLayer playerLayerWithPlayer:self.player];
    }
    return _layer;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    [self.view.layer addSublayer:self.layer];
}

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    [self.player play];
}

// 不加下面的方法,虽然可以放视频,可以听到声音
// 但是不能看到画面,得添加到相应的图层上去
- (void)viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];
    self.layer.frame = self.view.bounds;
}

@end

• 使用MPMoviePlayerViewController播放视频

• ViewController

// ViewController.h
#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

@end

// ViewController.m
#import "ViewController.h"
#import <MediaPlayer/MediaPlayer.h>

@interface ViewController ()

/** 播放器*/
@property (nonatomic, strong) MPMoviePlayerController *pc;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    // 0.获取资源路径
    NSURL *remoteURL = [NSURL URLWithString:@"http://v1.mukewang.com/57de8272-38a2-4cae-b734-ac55ab528aa8/L.mp4"];
    // 1.创建播放器对象
    self.pc = [[MPMoviePlayerController alloc] initWithContentURL:remoteURL];
    [self.view addSubview:self.pc.view];
}

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    [self.pc play];
}

- (void)viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];
    self.pc.view.frame = self.view.bounds;
}

@end

• 使用MPMoviePlayerViewController播放视频

• ViewController

// ViewController.h
#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

@end

// ViewController.m
#import "ViewController.h"
#import <MediaPlayer/MediaPlayer.h>

@interface ViewController ()
/** 播放器 */
@property (nonatomic ,strong) MPMoviePlayerViewController *pvc;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // 0.获取远程视频url
    NSURL *remoteURL = [NSURL URLWithString:@"http://v1.mukewang.com/57de8272-38a2-4cae-b734-ac55ab528aa8/L.mp4"];
    self.pvc = [[MPMoviePlayerViewController alloc] initWithContentURL:remoteURL];
}

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    if (self.presentedViewController) { // 已经有指向的控制器了
        return;
    }

    [self presentViewController:self.pvc animated:YES completion:^{
        [self.pvc.moviePlayer play];
    }];
}

@end

• iOS9.0之后, 需要使用AVPlayerViewController

• ViewController

// ViewController.h
#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

@end

// ViewController.m
#import "ViewController.h"
#import <AVKit/AVKit.h>
#import <AVFoundation/AVFoundation.h>

@interface ViewController ()
/** 播放器 */
@property (nonatomic ,strong) AVPlayerViewController *playerVC;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    self.playerVC = [[AVPlayerViewController alloc] init];
    // 0.获取远程视频url
    NSURL *remoteURL = [NSURL URLWithString:@"http://v1.mukewang.com/57de8272-38a2-4cae-b734-ac55ab528aa8/L.mp4"];
    AVPlayer *player = [[AVPlayer alloc] initWithURL:remoteURL];
    self.playerVC.player = player;
}

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    if (self.presentedViewController) { // 已经有指向的控制器
        return;
    }
    [self presentViewController:self.playerVC animated:YES completion:^{
        [self.playerVC.player play];
    }];
}

@end
