视频连续播放

如题，该怎么实现在播放所有的视频事前先播放一段广告，求思路。。。。。。

查了下文档，发现了这个东东MPMoviePlayerPlaybackDidFinishReasonUserInfoKey；
可以通过这样    NSNumber* reason = [[notification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];
    switch ([reason intValue]) {
        case MPMovieFinishReasonPlaybackEnded:
            NSLog(@"playbackFinished. Reason: Playback Ended");         
            break;
        case MPMovieFinishReasonPlaybackError:
            NSLog(@"playbackFinished. Reason: Playback Error");
            break;
        case MPMovieFinishReasonUserExited:
            NSLog(@"playbackFinished. Reason: User Exited");
            break;
        default:
            break;
    }进行不同的处理，谢谢大家的热情帮助了。。

 

答：

使用MPMoviePlayerController 
把它的view加到自己的view上。
增加一个播放结束的通知
播放完时，把播放器再用网络的url初始化，继续播放
理论上这么做是可以的

 

问：

不行，先不说别的，那个播放结束的通知有两种情况会调用，一是在播放完成后自动调用，二是在用户手动点完成的时候会调用，如果是第一种情况，还可以在播放结束的回调函数里在加载另外一个视频，但如果是手动点完成的话，这个视频就应该结束了，还怎么再去播放视频呢？所以就不能再这个回调函数里面再加载视频了，头大阿头大，还有木有高手给点意见？？

 

答：

你说地对，在点击完成button的时候，也会调用DidFinish函数
可以有种方法，可能比较麻烦，走弯路了，其他地方法没发现
检查当前正在播放的视频播放进度和总进度，如果一致证明是视频播放完时调用地，这时再检查当前是否是在播放广告，如果是，则继续播放视频，如果不是，说明视频已播放完，可调用dismiss函数。反之，则是用户点了完成按钮，应该dismiss窗口。
你觉得怎样？

 

问：

你好，我的问题现在是这样的，就是我要先播放一段我的本地视频（就是加广告），本地视频完了之后，再播放网络的视频。
但是，问题是本地视频的播放很不稳定，给我的感觉是当网络慢时，可以正常加载本地视频，紧接着播放网络视频；当网络快时，
本地视频就播放一瞬间，更为糟糕的是整个播放器都退出来了，连网络视频都播放不了了。以下是我的代码：
- (void)myMovieFinishedCallback:(NSNotification*)aNotification{
    
    NSDictionary *userInfo = [aNotification userInfo];
    NSLog(@"MPMoviePlayerPlaybackDidFinishReasonUserInfoKey: %@",
          [userInfo objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey]);
    
    NSNumber* reason = [[aNotification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];
    switch ([reason intValue]) {
        case MPMovieFinishReasonPlaybackEnded:
            NSLog(@"playbackFinished. Reason: Playback Ended");         
            break;
        case MPMovieFinishReasonPlaybackError:
            NSLog(@"playbackFinished. Reason: Playback Error");
            break;
        case MPMovieFinishReasonUserExited:
            NSLog(@"playbackFinished. Reason: User Exited");
            break;
        default:
            break;
    }
    
    MPMoviePlayerController* theMovie=[aNotification object];    
    [[NSNotificationCenter defaultCenter] removeObserver:self                                                    
                                                    name:MPMoviePlayerPlaybackDidFinishNotification                                                  
                                                  object:theMovie];    
    
    [theMovie release];
}  

- (void)playMovieAtURL:(NSURL*)theURL{  
    
    MPMoviePlayerController* theMovie= [[MPMoviePlayerController alloc] initWithContentURL:theURL];    
    theMovie.scalingMode=MPMovieScalingModeAspectFill;    
       
    // Register for the playback finished notification.    
    [[NSNotificationCenter defaultCenter] addObserver:self                                            
                                             selector:@selector(myMovieFinishedCallback:)                                                
                                                 name:MPMoviePlayerPlaybackDidFinishNotification                                              
                                               object:theMovie];     
    // Movie playback is asynchronous, so this method returns immediately.    
    [theMovie play];
} 

- (void)video_play:(NSString*)filename{    
    NSString* s = [[NSBundle mainBundle] pathForResource:filename ofType:@"mp4"];    
    NSURL* url = [NSURL fileURLWithPath:s];    
    NSLog(@"Playing URL: %@", url);    
    [self playMovieAtURL:url];
}


- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    NSLog(@"进入,%d,%@",navigationType,[[request URL]absoluteURL]);
    
    [self video_play:@"Hy_PLAY"];//Hy_PLAY.mp4是我的本地视频
    return YES;
}
  所以，我想问你下，怎么来控制本地视频，让它完整播放完之后，紧接着播放网络视频，而不会出现上面的问题，谢谢！

 

 

 

答：

你说的那种情况我到是没遇到，看了你的代码，感觉有些地方得指出来：
首先，将你在WebView的委托方法里面的 return YES 改成 return NO， 因为你是自己写的MpmoviePlayerController，若是是YES的话，系统会默认用自带的播放器进行播放，其次将你的MpMoviePlayer设置成全局的，在结束通知的方法里面这这样写

- (void) moviePlayBackDidFinish:(NSNotification*)notification
{
    NSNumber* reason = [[notification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];
    switch ([reason intValue]) {
        case MPMovieFinishReasonPlaybackEnded:{
            NSLog(@"playbackFinished. Reason: Playback Ended");
            if (Firstplay) {
                NSLog(@"11111111");
                [pWebVIew HidePlayingStatusView];
                if ([self IsDeviceIphone4OrHigher])
                {
                    [self ClearIphone4Setting];
                }
                
                //每次放完都release掉
                if ( nil != moviePlayer )
                {
                    [moviePlayer release];
                    moviePlayer = nil;        
                }
            }else {
                NSLog(@"222222222");
                [moviePlayer setContentURL:self.url];

                [moviePlayer play];
                Firstplay = TRUE;
            }
            
            
        }
            break;
        case MPMovieFinishReasonPlaybackError:{
            NSLog(@"playbackFinished. Reason: Playback Error");
            
        }
            break;
        case MPMovieFinishReasonUserExited:
            NSLog(@"playbackFinished. Reason: User Exited");
            [pWebVIew HidePlayingStatusView];
            
            if ([self IsDeviceIphone4OrHigher])
            {
                [self ClearIphone4Setting];
            }
            
            //每次放完都release掉
            if ( nil != moviePlayer )
            {
                [moviePlayer release];
                moviePlayer = nil;        
            }
            break;
        default:
            break;
    }
    

}
