iphone之MPMoviePlayer 视频…

原文地址：iphone之MPMoviePlayer 视频播放作者：飞舞的鸡毛  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=[[MPMoviePlayerViewController
alloc] initWithContentURL:url];

if
(tmpMoviePlayViewController)

{

self._moviePlayViewController=tmpMoviePlayViewController;

 

[self
presentMoviePlayerViewControllerAnimated:_moviePlayViewController];

_moviePlayViewController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;

[_moviePlayViewController.moviePlayer play];

}

[tmpMoviePlayViewController release];  

[[NSNotificationCenter
defaultCenter] addObserver:self
selector:@selector(playbackDidFinish) name:MPMoviePlayerPlaybackDidFinishNotification
object: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||[videoURL rangeOfString:@"https://"].location!=NSNotFound) 

    {

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

if (URL) {

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

{//3。2以后

MPMoviePlayerViewController*
tmpMoviePlayViewController=[[MPMoviePlayerViewController
alloc] 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:self
selector:@selector(playbackDidFinish) name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];

}
[URL
release];

    }

}

//视频播放完成后事件
-
(void) playbackDidFinish

{

   
[[NSNotificationCenter defaultCenter] removeObserver:self
name: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;

    }

}
