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;
}
