iOS UIDocumentInteractionController PDF 共享问题

Question

我想在应用程序中共享保存的PDF.实际上它不适用于PRINT和MAIL，而是通过Whatsapp和其他应用程序共享。

{
let fileManager = FileManager.default
let imagePAth = (Common.getDirectoryPath() as NSString).appendingPathComponent("invoice.pdf")
if fileManager.fileExists(atPath: imagePAth){
let url = URL (fileURLWithPath: localurlfile)
docController = UIDocumentInteractionController.init(url: url)
docController.presentOptionsMenu(from: self.view.frame, in: self.view, animated: true)
}else{
print("No Image")
}
}

Answer 1

您可以使用UIActivityViewController共享内容。

if let pdfFileUrl = URL(String("yourFileURL")) {
let vc = UIActivityViewController(activityItems: [pdfFileUrl], applicationActivities: [])
present(vc, animated: true)`enter code here`

}

Answer 2

查看和共享目的。

let controller = UIDocumentInteractionController(url: pdfurl)
controller.delegate = self
controller.presentPreview(animated: true)

并实现UIDocumentInteractionControllerDelegate。

extension ViewController: UIDocumentInteractionControllerDelegate {
func documentInteractionControllerViewControllerForPreview(_ controller: UIDocumentInteractionController) -> UIViewController {
return self
}
func documentInteractionControllerDidEndPreview(_ controller: UIDocumentInteractionController) {
}
}
