How can i insert/pass a value into a mail body from my Table View Cell in Xcode/Swift?

Question

Well I have a problem with my app. Just to say I m a beginner :) I have TableViewControler and I am using func with dequeueReusableCell to return a cell I that is ok. But the problem is how to implement this cell(s) with their values into a body mail using MFMailComposeViewController.setMessageBody? I m trying to pass an order which is in cells just like it is - in a table. That table a need to be visible in mail body. This parameter only takes String and cell is not visible (in scope here). Maybe should I transform cell into a html? And how should I do that?

//This values/cells I need to implement into a mail body//

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "OrderProductsCell", for: indexPath) as! OrderViewCell

    let rowData = orderedProducts[indexPath.row]
    cell.lblNameOfOrderProduct.text = rowData.selectedProducts.name + " " +  rowData.selectedProducts.packaging + " " + rowData.selectedProducts.volume + " " + String(rowData.stepperNumber) + " x(kom)"
    cell.lblFromDistributor.text = "Od"
    cell.lblToStore.text = "Za"
    cell.tfOrderFromDistibutor.text = String(rowData.distibutor)
    cell.tfOrderToStore.text = String(rowData.store)
    cell.tfOrderFromDistibutor.isUserInteractionEnabled = false
    cell.tfOrderToStore.isUserInteractionEnabled = false
   
  
    return cell
    
}

//This is MFMailComposeViewControlles - in the same Controller like Table View

func showMailComposer() {
    guard MFMailComposeViewController.canSendMail() else {
       defAlert(name: "You Can't sent mail", message: "")
        return
    }
    
    let composer = MFMailComposeViewController()
    composer.mailComposeDelegate = self
    composer.setToRecipients(["[email protected]"])
    composer.setSubject("Porudzbina")
    composer.setMessageBody ("Here i need to implement cell", isHTML: false) 
    present(composer,animated: true)
}

Do you just need the data that is in the tableView as text into the Mail view or you want the image of the TableView in your mail ? — Shawn Frank
Maybe you can add some code of tableview data methods such as numberOfRowsInSection and cellForRowAt indexPath which will be helpful to us to understand your issue. — Shawn Frank
@ShawnFrank I don't have images in cells only labels and text fields. So just data. I tried using that by index Path can't be found in scope inside MFMailComposeViewControler. I don't know is that enough you to understand, its a little confusing question... — Suncica Miladinovic
I think you should paste the code of what you tried which is crashing and this will be useful for anyone seeing this question and myself to debug your issue. — Shawn Frank
@ShawnFrank I edited the question with code. Nothing is crashing because I don't know how to do it :) — Suncica Miladinovic

I am not sure I understand your end goal completely, but let me share what I think you mean.

I believe you want all the texts from your table view to show inside the MailView as text.

And I understand all your products data is inside orderedProducts - correct me if I am wrong ?

So inside your showMailComposer function, you can maybe try this - I have added comments to new code I have added to your function:

func showMailComposer() {
    guard MFMailComposeViewController.canSendMail() else {
       defAlert(name: "You Can't sent mail", message: "")
        return
    }
    
    // Start empty string
    var stringBuilder = ""
    
    // Loop through all your products
    for orderedProduct in orderedProducts
    {
        // Append string builder with products
        // Add all product properties you want
        stringBuilder += "\(orderedProduct.name), \(orderedProduct.packaging) \n"
    }
    
    let composer = MFMailComposeViewController()
    composer.mailComposeDelegate = self
    composer.setToRecipients(["[email protected]"])
    composer.setSubject("Porudzbina")
    
    // Add string builder as text
    composer.setMessageBody (stringBuilder, isHTML: false)
    
    present(composer,animated: true)
}

Run this result and check if it is close to what you want.
