无法通过whatsapp分享pdf

Question

我有一个正在转换为 pdf 的 html 数据。现在我想通过whatsapp分享那个pdf。我试图像这样实现它......

  let pdfData = generatePDF(from: self.appDelegate.HTMLContent)

  let activityViewController:UIActivityViewController = UIActivityViewController(activityItems:  [pdfData], applicationActivities: nil)

self.present(activityViewController, animated: true, completion: nil)

但是当我选择发送的收件人时，收到消息This item cannot be shared. Please select a different item 但是可以通过消息应用程序进行共享。问题在于whatsapp。

也参考了这个链接..Share PDF through WhatsApp

但这并没有帮助......

Answer 1

您不能直接传递数据。您应该将 pdf 文件存储在 document 或 temp 目录中，然后传递 pdf 文件的 url。

let vc = UIActivityViewController(activityItems: [storeurl], applicationActivities: [])

self.present(vc, animated: true, completion: nil)

Answer 2

使用 DocumentInteractionController，您的问题将得到解决

let url = Bundle.main.url(forResource: "Sample", withExtension: "pdf")!
docController = UIDocumentInteractionController(url: url)
docController?.delegate = self
docController?.presentOptionsMenu(from: self.view.frame, in:self.view, animated:true)
