Get section number in custom cell button action

Question

I have a tableView dynamically populated with custom cells in several sections.

In my CustomCell class I have an @IBAction for a custom checkbox button in the cell.

Answer 1

I have recently come with a solution to this problem leveraging the use of Segues and implementing it in Swift 2.2 and XCode8.

I have a Custom Cell that I'm using for a header that has 2 Labels and a UIButton. All of my data is in an array and I want to dynamically access the data. Each section is an array of section headers and within that class the sections contain additional arrays to finish generating my tableView. My goal was to get the Index of the section based on a button click in the custom cell (header) and change the data in a different view.

To populate the tableView with my custom header cells I used:

override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let myCell = tableView.dequeueReusableCellWithIdentifier("REUSABLE ID")! as! MyHeaderCell
    let team = array[section]
    myCell.teamName.text = team.name
    myCell.projectName.text = team.project
    myCell.addMemberButton.tag = section        
    return myCell
}

Using the storyboard, the IBOutlet for the button (addMemberButton) in MyHeaderCell had the .tag field which I used to save the section index. So when I prepared segue I could use this value to dynamically access my array in the DataSource. As follows

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "segue1" {

        ...

    }else if segue.identifier == "AddMemberSegue"{
        let ix = sender?.tag
        let destVC = segue.destinationViewController as! AddMemberViewController
        self.myArray = array[ix!]
        destVC.delegate = self

    }else if segue.identifier == "segue3"{

       ...

    }
} 

Here the sender is the button, so the .tag field gives us the specific section index to access the correct location in the array

Hope this helps someone.
