UIActivityViewController中的共享WebView

Question

我在Json中获取PDF，检索它并将其显示在webview中，但我还需要它与UIActivityViewController共享，但是当我通过webview时它没有显示可用于共享的选项

我正在做以下事情：

 //I get the json
    if let url = URL(string: "http://10.1.80.106:9000/api/recibo/imprimir?vigencia=2015-06-30") {
        var urlRequest = URLRequest(url: url)
        urlRequest.setValue("application/pdf", forHTTPHeaderField: "Content-Type")
        urlRequest.setValue("aaaabbbccc", forHTTPHeaderField: "Authorization")

        //i create the webview
        let webView = UIWebView(frame: self.view.frame)
        webView.loadRequest(urlRequest as URLRequest)
        webView.scalesPageToFit = true
        let pdfVC = UIViewController()
        pdfVC.view.addSubview(webView)
        pdfVC.title = "Recibo de Pagamento"
        self.navigationController?.pushViewController(pdfVC, animated: true)


        //instantiate the UIActivityViewController for the share, and step the WebView as parameter
        let vc = UIActivityViewController(activityItems: [(webView.request?.url?.absoluteString) as Any], applicationActivities: [])

        if let popoverController = vc.popoverPresentationController {
            popoverController.sourceView = self.view
            popoverController.sourceRect = self.view.bounds
        }
        self.present(vc, animated: true, completion: nil)

    }

实际上，您也可以使用专为此特定目的而设计的QuickLook Framework，而不是WebView。您只需传递文件的位置并符合协议。它将呈现一个内部有文档的视图控制器。您还可以使用本机选项来共享文件。
