how to use uiswitch for selecting category in swift?

Question

Trying to create an if else statement for a UISwitch. Not exactly sure what goes in the if else statements to check whether the switch is on or off.

@IBAction func selectionLabel(sender: AnyObject) {
    if(<some condition>)
    // do something

    else
      //do something
}

Is this a correct way to use the switch?

Answer 1

The sender is the switch. Check if the switch is on by checking the on property:

@IBAction func selectionLabel(sender: AnyObject) {
    if let mySwitch = sender as? UISwitch {
        if mySwitch.on {
            // switch is on
        } else {
            // switch is off
        }
    }
}
