使用封装号的MPMoviePlayerViewController播放MP4视频

最近做了一个项目，简单播放MP4视频。使用网上源码进行简单封装 。 网络那一部分没有测试，读取本地视频没有问题。 以下是源码

源码：

// MyMoivePlayerView.h

#import <UIKit/UIKit.h>

#import <MediaPlayer/MediaPlayer.h>

@interface MyMoivePlayerView : UIViewController {

//sdk3.2以后

MPMoviePlayerViewController *_moviePlayViewController;

//sdk3.2以前

MPMoviePlayerController *_moviePlayerController;

}

//远程视频事件

- (void) playURLVideo;

//本地视频事件

- (void) playFileVideo;

-(void) initAndPlay:(NSString *)videoURL;

@property (nonatomic,retain) MPMoviePlayerViewController *_moviePlayViewController;

@property (nonatomic,retain) MPMoviePlayerController *_moviePlayerController;

@end

// MyMoivePlayerView.m

#import "MyMoivePlayerView.h"

@implementation MyMoivePlayerView

@synthesize _moviePlayViewController;

@synthesize _moviePlayerController;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

if (self) {

// Custom initialization

}

return self;

}

//本地视频事件

-(void) playFileVideo

{//此方法只是 3。2以后的方法

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

NSURL*url=[[NSURL alloc] initFileURLWithPath:path];

MPMoviePlayerViewController* tmpMoviePlayViewController=[[MPMoviePlayerViewController alloc]initWithContentURL:url];

if (tmpMoviePlayViewController)

{

self._moviePlayViewController=tmpMoviePlayViewController;

_moviePlayViewController.view.backgroundColor = [UIColor blackColor];

[_moviePlayViewController.moviePlayer play];

}

[tmpMoviePlayViewController release];

}

//远程视频事件

- (void) playURLVideo

{

}

//视频播放完成通知

[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(playbackDidFinish)name:MPMoviePlayerPlaybackDidFinishNotification object:nil];

}

////////////////调用地方：

-(void) buttonAction:(id)sender {

NSLog(@"ssssssssss");

MyMoivePlayerView* playerview = [[MyMoivePlayerView alloc] initWithNibName:nil bundle:nil];

[playerview.view setBackgroundColor:[UIColor clearColor]];

playerview.view.frame = self.bounds;

[self addSubview:playerview.view];

[playerview playFileVideo];

}
