iOS share extension, configurationItems (tableView) - ios

Question

please barer with me that I am completely new to swift and iOS..
I'm trying to make a "team select" on my share extension. Ideally I want to be able to tap the "Team" footer and select multiple teams from a table view, and at last share/post to the selected teams.
I have been following a tutorial from 2016, but I think it is outdated by now unfortunately, and I haven't been able to find one similar that is up to date. (if you know one please link)
I have created a TeamTableViewController.swift (UITableViewController) with a hardcoded teamList which I hope to populate in the share extension.
my UITableViewController file looks like this:
import UIKit
protocol TeamViewProtocol {
func sendingViewController(viewController: TeamTableViewController, sentItem: String)
}
class TeamTableViewController: UITableViewController {
var teamList: [String] = ["Team 1", "Team 2", "Team 3", "Team 4", "Team 5"]
var delegate: TeamViewProtocol?
override func viewDidLoad() {
super.viewDidLoad()
self.clearsSelectionOnViewWillAppear = false
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return self.teamList.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "TeamCell", for: indexPath)
cell.textLabel!.text = self.teamList[indexPath.item]
return cell
}
}
My ShareViewController filer looks like this:
import UIKit
import Social
class ShareViewController: SLComposeServiceViewController, TeamViewProtocol {
var item: SLComposeSheetConfigurationItem!
var teamPickerVC: TeamTableViewController!
override func isContentValid() -> Bool {
// Do validation of contentText and/or NSExtensionContext attachments here
return true
}
override func didSelectPost() {
// This is called after the user selects Post. Do the upload of contentText and/or NSExtensionContext attachments.
// Inform the host that we're done, so it un-blocks its UI. Note: Alternatively you could call super's -didSelectPost, which will similarly complete the extension context.
self.extensionContext!.completeRequest(returningItems: [], completionHandler: nil)
}
override func configurationItems() -> [Any]! {
self.item = SLComposeSheetConfigurationItem()
self.item.title = "Team"
self.item.value = "None"
self.item.tapHandler = {
self.teamPickerVC = TeamTableViewController()
self.pushConfigurationViewController(self.teamPickerVC)
}
return [self.item]
}
func sendingViewController(viewController: TeamTableViewController, sentItem: String) {
self.item.value = sentItem
self.popConfigurationViewController()
}
}
When I tap the extension window footer "Team" the entire extension dismisses with no error message. If however, I set the hard coded teamList array to an empty array, then the extensions does not crash/dismiss but instead shows the table view with empty rows.
What am I missing in order for my hard coded teams to show as cell/lines/rows? in the table view?

Answer 1

You should return the proper number of sections or can remove that method, so it will take the default value of numerOfSections as 1
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
Hope it helps

Answer 2

After a lot of trial and error. I finally found a forum post about the correct implementation of the tableView function that calls with the argument cellForRowAt
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCell(withIdentifier: "TeamCell")
if cell == nil {
cell = UITableViewCell(style: .default, reuseIdentifier: "TeamCell")
}
cell!.textLabel!.text = self.teamList[indexPath.item]
return cell!
}
This was not easy to debug, and there were no error or exceptions printed.

You also have to implement the didSelectRowAt delegate for the tableView to be able to send the selected item back to the main view.
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let selectedItem = self.teamList[indexPath.item]
delegate?.sendingViewController(viewController: self, sentItem: selectedItem)
self.navigationController?.popViewController(animated: true)
}
