I have multiple sections in table view. In sections, i have two textfield and some (Radio)Buttons.I have Submit Button in last cell.I want to get data on submit button @IBAction from textfields and selected buttons.

Answer 1

The most common way of doing this is by collecting the data whenever a textfield ends editing. Delegate method for UITextFieldDelegate textFieldDidEndEditing.

Answer 2

You can track the UIButton action from its position like below:

func getDataForButton(sender: UIButton!){
        let buttonPosition = sender.convert(sender.bounds.origin, to: tblView)
        let btnIndexPath = tblView.indexPathForRow(at: buttonPosition)

        // reload the particular row if needed or fetch the data
        tblView.reloadRows(at: [btnIndexPath!], with: .none)

    }
