关于 iphone:UIWebView 播放本地和下载的视频


UIWebView to Play Local and downloaded Video

我想使用 UIWebview 播放下载的视频。我得到 webkiterrordomain code=204 错误。
但如果我从资源文件夹播放视频，它运行完美。

NSString *tempurl = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"video.mp4"];
   //from downloaded file
 NSString *tempurl = downloaded path;
NSURL* urlLocation = [NSURL fileURLWithPath:tempurl];
[webView loadRequest:[NSURLRequest requestWithURL:urlLocation]];

谢谢。

解决方案来了，你可以在 Embedded UIWebView 中播放视频。

[super viewDidLoad];

NSString *embedHTML = @"\\

</body></html>";

webView = [[UIWebView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 412.0)];

[webView setOpaque:NO];
NSString *html = [NSString stringWithFormat:embedHTML, webView.frame.size.width, webView.frame.size.height];
[webView loadHTMLString:html baseURL:nil];

[self.view addSubview:webView];

}

WebkitErrorDomain 204 只是意味着它将在 MPInlinePlayerController 上播放视频。因此，您只需忽略错误，视频就会播放。

生成一个html。将您的视频嵌入其中。在项目资源中包含 html 和视频文件。然后从 webview 加载 html。

要播放本地视频文件，您可以使用 MPMoviePlayerController。
