iphone之MPMoviePlayer 视频播放

  iphone的视频播放官方的例子有问题。这次是费了比较长的时间。

    原因是在sdk3.2以后。视频这一块官方有很大的改动造成的。

 

远程视频：

本地视频：

首先需要引入视频包；

代码如下：

#import <UIKit/UIKit.h>

#import <MediaPlayer/MediaPlayer.h>

@interface View24 : UIViewController 

{

//sdk3.2以后

MPMoviePlayerViewController *_moviePlayViewController;

//sdk3.2以前

MPMoviePlayerController *_moviePlayerController;

 

}

//远程视频事件

- (IBAction) playURLVideo;

//本地视频事件

- (IBAction) playFileVideo;

@property (nonatomic,retain) MPMoviePlayerViewController *_moviePlayViewController;

@property (nonatomic,retain) MPMoviePlayerController *_moviePlayerController;

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

@end

//本地视频事件

-(IBAction) playFileVideo

{//此方法只是 3。2以后的方法

NSString *path=[[NSBundle mainBundle] pathForResource:@"sophie" ofType:@"mov"];

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

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

if (tmpMoviePlayViewController)

{

self._moviePlayViewController=tmpMoviePlayViewController;

 

[self presentMoviePlayerViewControllerAnimated:_moviePlayViewController];

_moviePlayViewController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;

[_moviePlayViewController.moviePlayer play];

}

[tmpMoviePlayViewController release];  

[[NSNotificationCenter defaultCenter] addObserver:selfselector:@selector(playbackDidFinish) name:MPMoviePlayerPlaybackDidFinishNotificationobject:nil];

 

}

 

//远程视频事件

- (IBAction) playURLVideo

{

NSString *videoPath =@"http://www.subfurther.com/video/running-start-iphone.m4v";

if (videoPath == NULL)

return;

 

[self initAndPlay:videoPath];

 

}

-(void) initAndPlay:(NSString *)videoURL

{

    if ([videoURL rangeOfString:@"http://"].location!=NSNotFound||[videoURLrangeOfString:@"https://"].location!=NSNotFound) 

    {

NSURL *URL = [[NSURL alloc] initWithString:videoURL];

if (URL) {

if ([[[UIDevice currentDevice] systemVersion] doubleValue] >= 3.2)

{//3。2以后

MPMoviePlayerViewController* tmpMoviePlayViewController=[[MPMoviePlayerViewControlleralloc] initWithContentURL:URL];

if (tmpMoviePlayViewController)

{

self._moviePlayViewController=tmpMoviePlayViewController;

 

[self presentMoviePlayerViewControllerAnimated:_moviePlayViewController];

_moviePlayViewController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;

[_moviePlayViewController.moviePlayer play];

}

[tmpMoviePlayViewController release];    

}

else if([[[UIDevice currentDevice] systemVersion] doubleValue] < 3.2)

{//3。2以前

MPMoviePlayerController* tmpMoviePlayController=[[MPMoviePlayerController alloc]initWithContentURL:URL];

if (tmpMoviePlayController)                      

{

self._moviePlayerController=tmpMoviePlayController;

[_moviePlayerController play];

}

[tmpMoviePlayController release];

}

//视频播放完成通知

[[NSNotificationCenter defaultCenter] addObserver:selfselector:@selector(playbackDidFinish) name:MPMoviePlayerPlaybackDidFinishNotificationobject:nil];

}

[URL release];

    }

}

//视频播放完成后事件

- (void) playbackDidFinish

{

    [[NSNotificationCenter defaultCenter] removeObserver:selfname:MPMoviePlayerPlaybackDidFinishNotification object:nil];  

    if (_moviePlayViewController)

    {

        [self dismissMoviePlayerViewControllerAnimated];

        [self._moviePlayViewController.moviePlayer stop];

        _moviePlayViewController.moviePlayer.initialPlaybackTime=-1.0;

        [_moviePlayViewController release];

        _moviePlayViewController=nil;

    }

    if (_moviePlayerController) 

    {

        [self._moviePlayerController stop];

        _moviePlayerController.initialPlaybackTime = -1.0;

        [_moviePlayerController release];

        _moviePlayerController = nil;

    }

}
