本文主要是介绍iOS 加载网络视频之（AVFoundation.framewor）的MPMoviePlayerController，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
//引用 AVFoundation.framework
#import "FirstViewController.h"
#import <MediaPlayer/MediaPlayer.h>
@interfaceFirstViewController ()
//视频播放器
@property (strong,nonatomic) MPMoviePlayerController *player;
@property (strong,nonatomic) UIImageView *imageView;
@end
@implementation FirstViewController
- (void)viewDidLoad {
[superviewDidLoad];
}
- (void)viewWillAppear:(BOOL)animated {
}
- (IBAction)media:(UIButton *)sender {
// 本地视频
// NSURL *url = [[NSBundle mainBundle]URLForResource:@"1" withExtension:@"mp4"];
// url = [NSURL URLWithString:@"http://devimages.apple.com/iphone/samples/bipbop/gear1/prog_index.m3u8"];
// 网络视频
// 提示：如果url中包含中文，需要添加百分号。
NSString *urlString =@"http://devimages.apple.com/iphone/samples/bipbop/gear1/prog_index.m3u8";
NSURL *url = [NSURLURLWithString:[urlStringstringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
//实例化视频播放器
self.player = [[MPMoviePlayerControlleralloc]initWithContentURL:url];
//1设置播放器的大小
[self.player.viewsetFrame:CGRectMake(0,200, self.view.frame.size.width,180)]; //16:9是主流媒体的样式
//2将播放器视图添加到根视图
[self.viewaddSubview:self.player.view];
//异步视频截图,可以在attimes指定一个或者多个时间。
[self.playerrequestThumbnailImagesAtTimes:@[@10.0f,@20.0f] timeOption:MPMovieTimeOptionNearestKeyFrame];
// UIImageView *thumbnailImageView = [[UIImageView alloc]initWithFrame:CGRectMake(80, 200, 160, 90)];
// self.imageView = thumbnailImageView;
// [self.view addSubview:thumbnailImageView];
//视频播放是流媒体的播放模式，所谓流媒体就是把视频数据像流水一样，边加载，边播放。
//4播放
// [self.player play];
//暂停
// [self.player stop];
//通过通知中心，以观察者模式监听视频播放状态
//1 监听播放状态
[[NSNotificationCenterdefaultCenter]addObserver:selfselector:@selector(stateChange)name:MPMoviePlayerPlaybackStateDidChangeNotificationobject:nil];
//2 监听播放完成
[[NSNotificationCenterdefaultCenter]addObserver:selfselector:@selector(finishedPlay)name:MPMoviePlayerPlaybackDidFinishNotificationobject:nil];
//3视频截图
[[NSNotificationCenterdefaultCenter]addObserver:selfselector:@selector(caputerImage:)name:MPMoviePlayerThumbnailImageRequestDidFinishNotificationobject:nil];
//3视频截图
[[NSNotificationCenterdefaultCenter]addObserver:selfselector:@selector(caputerImage:)name:MPMoviePlayerThumbnailImageRequestDidFinishNotificationobject:nil];
//4退出全屏通知
