How do you use an if/else statement with an ActionSheet?

Question

In my app I'm creating, I have an ActionSheet with some options. When the user selects an option, I want the label to change to what he/she chose. I tried an if/else statement, but I obviously did not create it correctly-

@IBAction func showActionSheet(sender: AnyObject) {

    var optionMenu = UIAlertController(title: nil, message: "Choose a Factor", preferredStyle: .ActionSheet)


    let factorActionCageRest = UIAlertAction(title: "Cage Rest", style: .Default, handler: {
        (alert: UIAlertAction!) -> Void in
        print("File Deleted")
    })

    let factorActionAfterSurgery = UIAlertAction(title: "After Surgery", style: .Default, handler: {
        (alert: UIAlertAction!) -> Void in
        print("File Saved")
    })

    let factorActionTrauma = UIAlertAction(title: "Trauma", style: .Default, handler: {
        (alert: UIAlertAction!) -> Void in
        print("File Saved")
    })

    let factorActionSepsis = UIAlertAction(title: "Sepsis", style: .Default, handler: {
        (alert: UIAlertAction!) -> Void in
        print("File Saved")
    })

    let factorActionSevereBurn = UIAlertAction(title: "Severe Burn", style: .Default, handler: {
        (alert: UIAlertAction!) -> Void in
        print("File Saved")
    })

    let factorCancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: {
        (alert: UIAlertAction!) -> Void in
        print("Cancelled")
    })


    optionMenu.addAction(factorActionCageRest)
    optionMenu.addAction(factorActionAfterSurgery)
    optionMenu.addAction(factorActionTrauma)
    optionMenu.addAction(factorActionSepsis)
    optionMenu.addAction(factorActionSevereBurn)
    optionMenu.addAction(factorCancelAction)

    if optionMenu.addAction() = factorActionCageRest {
        var factorActionOutput = 1.25
        factorLabel.text = "\(factorActionOutput)"
    }
    self.presentViewController(optionMenu, animated: true, completion: nil)

}

@IBOutlet weak var factorLabel: UILabel!
var factorActionOutput = Float()


}

Question- How do I apply an if/else statement to the user's option? Thanks!

Update your UIAlertAction handler to include the code for changing the label.

let factorActionCageRest = UIAlertAction(title: "Cage Rest", style: .Default, handler: {
    [weak self] (alert: UIAlertAction!) -> Void in
    print("File Deleted")
    let factorActionOutput = 1.25
    self?.factorLabel.text = "\(factorActionOutput)"
})
