Webview 或 MPMoviePlayerViewController 中的 iOS 流式视频答案

【问题标题】：iOS streaming video in webview or MPMoviePlayerViewControllerWebview 或 MPMoviePlayerViewController 中的 iOS 流式视频

【问题描述】：

我必须从服务器流式传输视频 (.mov)。我使用 UIWebView，它运行良好，但委托方法

- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error;

总是调用而不是

- (void)webViewDidFinishLoad:(UIWebView *)webView;

我打印错误：

Error Domain=WebKitErrorDomain Code=204 "Plug-in handled load" (...)

后来我决定改用MPMoviePlayerViewController。看起来更慢！使用 UIWebView 流式传输视频是一个好习惯吗？如何修复我的错误？有没有适合我的快速解决方案？

提前谢谢你

再次，如果您决定使用MPMoviePlayerViewController。试试这个...

-(IBAction)btnVideoClicked:(id)sender
{
    @try 
    {
        NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init];
        GetVideos *obj_video = [arrVideos objectAtIndex:[sender tag]];
        MPMoviePlayerViewController *moviePlayerViewController = [[MPMoviePlayerViewController alloc]initWithContentURL:[NSURL URLWithString:obj_video.VideoPath]];
        [moviePlayerViewController.moviePlayer setControlStyle:MPMovieControlStyleFullscreen];
        [moviePlayerViewController.moviePlayer setShouldAutoplay:YES];
        [moviePlayerViewController.moviePlayer setFullscreen:NO animated:YES];
        [moviePlayerViewController setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
        [moviePlayerViewController.moviePlayer setScalingMode:MPMovieScalingModeNone];
        [moviePlayerViewController.moviePlayer setUseApplicationAudioSession:NO];
        // Register to receive a notification when the movie has finished playing.  
        [[NSNotificationCenter defaultCenter] addObserver:self    selector:@selector(moviePlaybackStateDidChange:)      name:MPMoviePlayerPlaybackStateDidChangeNotification    object:moviePlayerViewController];
        // Register to receive a notification when the movie has finished playing.  
        [[NSNotificationCenter defaultCenter] addObserver:self     selector:@selector(moviePlayBackDidFinish:)    name:MPMoviePlayerPlaybackDidFinishNotification     object:moviePlayerViewController];
        [self presentMoviePlayerViewControllerAnimated:moviePlayerViewController];
        moviePlayerViewController.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
        [moviePlayerViewController release];
        [pool release];
    }
    @catch (NSException *exception) {
        // throws exception
    }
}
