call multiple button in a UITableviewcell

Question

I have a xib file with 4 buttons and each button has a function which it has to start when clicked. The function has to fetch data and after it has fetched data it should perform a segue. I am only allowed to use a nib which is of type UITableViewCell and show it in a tableview inside a viewcontroller.

Is it possible to get each button to start the required function when tapped in the tableviewcell, if so how do i go about it.

I have looked at questions similar to mine for days and tried all the suggested solutions and they arent working e.g.

Show ViewController from XIB-file-Button - Swift

Perform segue from button in XIB

Swift - Segue from Button inside a cell

Perform segue from button in XIB

Perform Segue from Xib programmatically

Sure, it's pretty simple in the code to have the event passed in the action and then access the index path.

First add the target to your button.

button.addTarget(self, action: #selector(someAction(_:event:)), for: .touchUpInside)

Then use this code to start your action.

@objc func someAction(_ button: UIButton, event: UIEvent) {
    guard let location = event.allTouches?.first?.location(in: tableView),
        let indexPath = tableView?.indexPathForItem(at: location)
        else {
            return
    }

    // TODO: fetch data

    performSegue(withIdentifier: "mySegueID", sender: button)
}

Also if your data is async, you could use something like PromiseKit. https://github.com/mxcl/PromiseKit

Where does the function sit because my code to fetch data is in the nib class – Erent Jun 16 '18 at 20:06
You can make a controller object (which inherits from NSObject or nothing) and call it from there. – cnotethegr8 Jun 16 '18 at 20:09
like a viemodel? – Erent Jun 16 '18 at 20:10
If your designing based on MVVM then sure, otherwise you can simply refer to it as a controller. – cnotethegr8 Jun 16 '18 at 20:12
