I'm trying to populate a custom cell with an action button - swift

Question

I'm using a custom cell class to populate a tableview in swift.
I need to get it working for an array of buttons so that each cell has a button that performs an IBAction function unique to that cell.
Here's my cell class declaring the button variable:
class taskCell: UITableViewCell {
#IBOutlet weak var performTask: UIButton!
//ignoring code irrelevant to question
}
All of my "tasks" that I want to happen when the button is pressed are a variation of the following pattern:
#IBAction func task1(sender: AnyObject){
if (prerequisite1 >= 1 ) {
prerequisite1 = prerequisite1 - 1;
points = points + 400;
prerequisite1Label.text = "\(prerequisite1)";
pointsLabel.text = "\(points)";
}
}
#IBAction func task2(sender: AnyObject){
if (prerequisite2 >= 1 ) {
prerequisite2 = prerequisite2 - 1;
points = points + 600;
prerequisite1Label.text = "\(prerequisite2)";
pointsLabel.text = "\(points)";
}
}
Here's my attempt to put them in an array in my viewController that the table is in:
let firstTasks:[()->()] = [tasksViewController().task1(), tasksViewController().task2()]
And finally here is my attempt at implementing it implementing it in the tableview:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! JobCell
cell.performTask.tag = indexPath.row
cell.performTask.addTarget(self, action: firstTasks[indexpath.row], forControlEvents: .TouchUpInside)
return cell
}

Answer 1

Instead of keeping the functions array. Why don't you do something like this:
class JobCell: UITableViewCell {
#IBOutlet weak var performTask: UIButton!
var actionBlock: (sender: AnyObject?) -> Void?
func someFunc() {
performTask. addTargetself, action: #selector(JobCell.didTapButton(_:)), forControlEvents: .TouchUpInside)
}
func didTapButton(sender: AnyObject) {
actionBlock?(sender)
}
}
In viewController:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! JobCell
cell.actionBlock = {(sender) in
// do ur thing
}
return cell
}
