This is my h5 code: <video id="myVideo" src="xxxapp://xxx.xxx.xx/xxx/xxx.mp4" style="object-fit:cover;opacity:1;width:100%;height:100%;display:block;possition:absolute;" type="video/mp4"></video> I want to load local large video, so, I use WKURLSchemeHandler. - (void)webView:(WKWebView *)webView startURLSchemeTask:(id<WKURLSchemeTask>)urlSchemeTask { NSURLRequest *request = [urlSchemeTask request]; NSURL *url = request.URL; NSString *urlString = url.absoluteString; NSString *videoPath = [[NSBundle mainBundle] pathForResource:@"xxx" ofType:@"mp4"]; NSData *videoData = [NSData dataWithContentsOfFile:videoPath options:nil error:nil]; NSURLResponse *response = [[NSURLResponse alloc] initWithURL:url MIMEType:@"video/mp4" expectedContentLength:videoData.length textEncodingName:nil]; [urlSchemeTask didReceiveResponse:response]; [urlSchemeTask didReceiveData:videoData]; [urlSchemeTask didFinish]; } but its not work, data is not nil, but video do not play. I would greatly appreciate it if someone could help me find a solution!! ps: can make it, but we cannot use it due to some reasons.
