IOS视频播放器的制作

利用自带MPMoviePlayerController来实现视频播放，首先要在项目中导入MediaPlayer.Framework框架包。

在视图控制器中

#import "MediaPlayer/MPMoviePlayerController.h"

 

.m文件中，加入一下代码

- (void)viewDidLoad

{

    [super viewDidLoad];

    self.navigationController.navigationBar.hidden=YES;

    //geomancy.jpg

    UIImageView * nanshanImage=[[UIImageView alloc]initWithFrame:CGRectMake(0,0,1024,699)];

    nanshanImage.image=[UIImage imageNamed:@"geomancy.jpg"];

    [self.view addSubview:nanshanImage];

    [nanshanImage release];

    //播放视频按钮

    UIButton* playButton= [[UIButton alloc]initWithFrame:CGRectMake(145, 250, 70, 80)];

    [playButton addTarget:self action:@selector(PlayMovieAction:) forControlEvents:UIControlEventTouchUpInside];

     playButton.backgroundColor=[UIColor redColor];

    [self.view addSubview:playButton];

    [playButton release];

    

}

-(void)PlayMovieAction:(id)sender{

   // NSLog(@"PlayMovieAction====");

    //视频文件路径，此视频已经存入项目包中。属于本地播放

    NSString *path = [[NSBundle mainBundle] pathForResource:@"jinxiuMovie" ofType:@"mp4"];

    //视频URL

    NSURL *url = [NSURL fileURLWithPath:path];

    //视频播放对象

    MPMoviePlayerController *movie = [[MPMoviePlayerController alloc] initWithContentURL:url];

    movie.controlStyle = MPMovieControlStyleFullscreen;

    [movie.view setFrame:self.view.bounds];

     movie.initialPlaybackTime = -1;

    [self.view addSubview:movie.view];

    // 注册一个播放结束的通知，当播放结束时，监听到并且做一些处理

//播放器自带有播放结束的通知，在此仅仅只需要注册观察者监听通知即可。

    [[NSNotificationCenter defaultCenter] addObserver:self

                                             selector:@selector(myMovieFinishedCallback:)

                                                 name:MPMoviePlayerPlaybackDidFinishNotification

                                               object:movie];

    [movie play];

}

-(void)myMovieFinishedCallback:(NSNotification*)notify

{

    //视频播放对象

    MPMoviePlayerController* theMovie = [notify object];

    //销毁播放通知

    [[NSNotificationCenter defaultCenter] removeObserver:self

                                                    name:MPMoviePlayerPlaybackDidFinishNotification

                                                  object:theMovie];

    [theMovie.view removeFromSuperview];

    // 释放视频对象，此对象由上面建立视频对象时候所alloc,在此做释放操作

    [theMovie release];

    // NSLog(@"视频播放完成");

}
