How to Create PDF as a screen shot from UITableView & Display & Share it

1. Add your UIViewController which has your TableView with your custom design .

2. Connect your TableView & Add Delegate.

3. In file viewController inherit UIDocumentInteractionControllerDelegate & Add delegate method :

   func documentInteractionControllerViewControllerForPreview(_ controller: UIDocumentInteractionController) -> UIViewController {
      return self
   }
   

4. Add button to test create pdf of your table view

5. Add this method for used with your file name :

   func pdfDataWithTableView(tableView: UITableView)-> String {
    let priorBounds = tableView.bounds
   
    let fittedSize = tableView.sizeThatFits(CGSize(
    width: priorBounds.size.width,
   height: tableView.contentSize.height
   ))
   
   tableView.bounds = CGRect(
   x: 0, y: 0,
   width: fittedSize.width,
   height: fittedSize.height
   )
   
   let pdfPageBounds = CGRect(
   x :0, y: 0,
   width: tableView.frame.width,
   height: self.view.frame.height
   )
   
   let pdfData = NSMutableData()
   UIGraphicsBeginPDFContextToData(pdfData, pdfPageBounds, nil)
   
   var pageOriginY: CGFloat = 0
   while pageOriginY < fittedSize.height {
   UIGraphicsBeginPDFPageWithInfo(pdfPageBounds, nil)
   UIGraphicsGetCurrentContext()!.saveGState()
   UIGraphicsGetCurrentContext()!.translateBy(x: 0, y: -pageOriginY)
   tableView.layer.render(in: UIGraphicsGetCurrentContext()!)
   UIGraphicsGetCurrentContext()!.restoreGState()
   pageOriginY += pdfPageBounds.size.height
   tableView.contentOffset = CGPoint(x: 0, y: pageOriginY) // move "renderer"
   }
   UIGraphicsEndPDFContext()
   
   tableView.bounds = priorBounds
   var docURL = (FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)).last! as URL
   docURL = docURL.appendingPathComponent("Report.pdf")
   pdfData.write(to: docURL as URL, atomically: true)
   
   return docURL.path
   }
   

6. in Your button action call this & send your tableView wil represent your pdf :

   let pdf_file = UIDocumentInteractionController(url: URL(fileURLWithPath: self.pdfDataWithTableView(tableView: self.tableView)))
   pdf_file.delegate = self
   pdf_file.presentPreview(animated: true)
