在视图中添加视频播放器 和 音频播放器

视频播放器 MPMoviePlayerController

#import "RootViewController.h"

#import <MediaPlayer/MediaPlayer.h>

@interface RootViewController ()

@property(nonatomic, retain) MPMoviePlayerController *moviePlayer;

@end

@implementation RootViewController

- (void)viewDidLoad {

    [super viewDidLoad];

    // Do any additional setup after loading the view.

    self.view.backgroundColor = [UIColor whiteColor];

    [self.view addSubview:self.moviewPlayer.view];
