我如何使用UISwitch来关闭本地通知？

Question

任何人都可以帮助我如何使用UISwitch的状态来打开/关闭在Appdelegate.swift中声明的本地通知？

Viewcontroller.swift：

@IBOutlet weak var switchButton: UISwitch! 
var switchState = true 
let switchKey = "switchState" 

@IBAction func saveSwitchPressed(sender: AnyObject) { 
    NSUserDefaults.standardUserDefaults().setBool(switchButton.on, forKey: "switchState") 
} 

override public func viewDidLoad() { 
    super.viewDidLoad() 
    switchButton.on = NSUserDefaults.standardUserDefaults().boolForKey("switchState") 
} 

AppDelegate.swift

func handleRegionEvent(region: CLRegion) { 
    // Show an alert if application is active 
    if UIApplication.sharedApplication().applicationState == .Active { 
    if let message = notefromRegionIdentifier(region.identifier) { 
     if let viewController = window?.rootViewController { 
     showSimpleAlertWithTitle(nil, message: message, viewController: viewController) 
     } 
    } 
    } else { 
    // Otherwise present a local notification 
    let notification = UILocalNotification() 
    notification.alertBody = notefromRegionIdentifier(region.identifier) 
    notification.soundName = "Default"; 
    UIApplication.sharedApplication().presentLocalNotificationNow(notification) 
    } 
}

这应该可以使用targetAction

override public func viewDidLoad() { 
     super.viewDidLoad() 
     switchButton.on = NSUserDefaults.standardUserDefaults().boolForKey("switchState") 

     //Set button to observe target action 
     switchButton.addTarget(self, action: "presentNotification", forControlEvents: UIControlEvents.ValueChanged) 
    } 

    func presentNotification() { 
     //Do notification stuff here 

    }
