如何禁用UISlider Swift

Question

I've seen answers about this but no actual code explaining how to, I'm new to swift so really confused on how to perform this simple task.

I have a UISlider However I want to disable the sliders funcation when an IF statement is true.

I current have a UISlider with an If statement but can't workout how to disable it.

    @IBAction func radiusSlider(sender: UISlider) {
    if location == false {
    //Disable Slider
    } else {
            radiusData.radiusValue = Double(sender.value)
            radiusLabel.text = "Radius: \(sender.value)km"
            NSNotificationCenter.defaultCenter().postNotificationName(radiusValue, object: self)
    }
}

Or would this be in within the viewDidLoad? If so how?

All help is appreciated

Set the enabled property to false.

@IBAction func radiusSlider(sender: UISlider) {
    if location == false {
        sender.enabled = false
    } else {
        radiusData.radiusValue = Double(sender.value)
        radiusLabel.text = "Radius: \(sender.value)km"
        NSNotificationCenter.defaultCenter().postNotificationName(radiusValue, object: self)
    }
}

If you want to enable/disable your slider in other functions of your view controller, you will need to make an IBOutlet property for your slider.
