1、音频播放，

需要引入系统库文件AVFoundation.framework,并加上头文件：

#import <AVFoundation/AVFoundation.h>

- (void)readPoemVoiceAtIndex:(NSInteger )index

{

    NSString *poemVoice = [_poemVoiceArray objectAtIndex:index];

    //    NSLog(@"%@",read);

    NSString *path = [[NSBundle mainBundle]pathForResource:poemVoice ofType:@"wav"];

    if (!path) {  return;    }//AVAudioPlayer的初始化任务可以放到一个一步线程中，这样有益于用户体验。

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

        NSURL *url = [NSURL fileURLWithPath:path];

        NSError *error;

        self.player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];

        [_player prepareToPlay];

        dispatch_async(dispatch_get_main_queue(), ^{

            self.player.volume =0.5;// _poemSet.volume;

           [_player play];

        });

    });

}

1、视频播放，

进行视频操作需要引入库MediaPlayer.framework,并加入头文件：

#import <MediaPlayer/MediaPlayer.h>

-(void)moveStep1

{

#pragma mark - make appStar animation

    /*添加视屏播放开启界面，使用到通知中心的方法，用于监听视频播放完毕*/

    //    NSString *url=[[NSBundle mainBundle]pathForResource:@"Comp 9" ofType:@"mov"];

    NSString *url=[[NSBundle mainBundle]pathForResource:@"mov_bbb" ofType:@"mp4"];

    _player=[[MPMoviePlayerController alloc]initWithContentURL:[NSURL fileURLWithPath:url]];

    _player.view.transform = CGAffineTransformMakeRotation(1.57);

    [[NSNotificationCenter defaultCenter]

     addObserver:self

     selector:@selector(beginView) name:MPMoviePlayerPlaybackDidFinishNotification object:_player];

    _player.scalingMode=MPMovieScalingModeAspectFill;　　

　　_player.controlStyle=MPMovieControlStyleNone;

　　_player.view.frame=CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width, [[UIScreen mainScreen] 　　bounds].size.height);

　　[_player setFullscreen:YES animated:YES];

　　[self.window addSubview:_player.view];

　　[_player play];

}

-(void)beginView

{    [[NSNotificationCenter defaultCenter]removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:_player];

    [_player.view removeFromSuperview];  

//    self.window.rootViewController = xueIntbc;

}
