iOS 调用音乐播放以及视频播放器

音乐播放

NSString *path = [[NSBundle mainBundle] pathForResource:@"预谋" ofType:@"mp3"];

    if (path) {

        NSURL *url = [NSURL fileURLWithPath:path];

        player= [[AVAudioPlayer alloc]initWithContentsOfURL:url error:nil];

        [player setDelegate:self];

        player.volume = 1;

        player.pan = 1;

        player.numberOfLoops = -1;

        if ([player prepareToPlay]) {

            NSLog(@"prepareToPlay:%@",path);

            [player play];

        } else {

            NSLog(@"no prepareToPlay");

        }

        //[player release];

    }

一定要注意player的引用，假设直接在函数内部申请一个暂时变量。那么这个player会在函数运行完毕，运行release 会被释放掉，假设须要在函数内部使用。那么请sleep下。只是这样会阻塞主线程的运作

视频播放器

NSURL * movieurl = [NSURL URLWithString:@"http://v.youku.com/player/getRealM3U8/vid/XNDUwNjc4MzA4/type/video.m3u8"];

    MPMoviePlayerViewController *player = [[MPMoviePlayerViewController alloc] initWithContentURL:movieurl];

    [self presentMoviePlayerViewControllerAnimated:player];
