Stop notifications at specific time using UIDatePicker - ios

Question

I managed to setup notifications using a UIDatePicker but my problem is that I want to make them stop by using an other UIDatePicker (datePickerStop).
So basically it Schedules to start and end notifications with two different UIDatePickers inside a Switch object and an if statement.
This is code that I have but it doesn't seem to work or I don't place it in the right place.
Any ideas?
let notificationArray = UIApplication.sharedApplication().scheduledLocalNotifications!
for notification in notificationArray {
if notification.fireDate == fixedNotificationDate(datePickerStop.date) {
UIApplication.sharedApplication().cancelLocalNotification(notification)
}
}
This is the complete code
override func viewDidLoad() {
super.viewDidLoad()
updateUI()
let defaults = NSUserDefaults.standardUserDefaults()
if (defaults.objectForKey("SwitchState") != nil) {
SwitchOutlet.on = defaults.boolForKey("SwitchState")
}
if (SwitchOutlet.on) {
Label1Outlet.text = "Notifications are On"
} else {
Label1Outlet.text = "Notifications are Off"
}
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func Switch(sender: AnyObject) {
let defaults = NSUserDefaults.standardUserDefaults()
if (SwitchOutlet.on) {
Label1Outlet.text = "Notifications are On"
defaults.setBool(true, forKey: "SwitchState")
let notification = UILocalNotification()
notification.fireDate = fixedNotificationDate(datePicker.date)
notification.repeatInterval = NSCalendarUnit.Minute
notification.alertBody = “Message”
notification.alertAction = “Lock!”
notification.soundName = "NotifSound.caf"
notification.userInfo = ["CustomField1": "w00t"]
guard let settings = UIApplication.sharedApplication().currentUserNotificationSettings() else { return }
if settings.types == .None {
let ac = UIAlertController(title: "Can't Activate", message: "Either we don't have permission to schedule notifications, or we haven't asked yet.", preferredStyle: .Alert)
ac.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
presentViewController(ac, animated: true, completion: nil)
return
}
UIApplication.sharedApplication().scheduleLocalNotification(notification)
} else {
Label1Outlet.text = "Notifications are Off"
defaults.setBool(false, forKey: "SwitchState")
UIApplication.sharedApplication().cancelAllLocalNotifications()
}
}
func fixedNotificationDate(dateToFix: NSDate) -> NSDate {
let dateComponents: NSDateComponents = NSCalendar.currentCalendar().components([NSCalendarUnit.Day, NSCalendarUnit.Month, NSCalendarUnit.Year, NSCalendarUnit.Hour, NSCalendarUnit.Minute], fromDate: dateToFix)
dateComponents.second = 0
let fixedDate: NSDate = NSCalendar.currentCalendar().dateFromComponents(dateComponents)!
return fixedDate
}
func updateUI() {
let currentSettings = UIApplication.sharedApplication().currentUserNotificationSettings()
if currentSettings?.types != nil {
if currentSettings!.types == [UIUserNotificationType.Badge, UIUserNotificationType.Alert] {
}
else if currentSettings!.types == [UIUserNotificationType.Badge] {
}
else if currentSettings!.types == UIUserNotificationType.None {
}
}
}
}

You can add userInfo to your notification when scheduled
let notification:UILocalNotification = UILocalNotification()
notification.userInfo = ["day": day, "hour": hour]
UIApplication.sharedApplication().scheduleLocalNotification(notification)
And when you are trying to cancel just find it with the userInfo
let app = UIApplication.sharedApplication()
let day: Int = 1
let hour: Int = 2
for singleNotification in app.scheduledLocalNotifications!{
let notDay = singleNotification.userInfo!["day"] as! Int
let notHour = singleNotification.userInfo!["hour"] as! Int
if(notDay == day && notHour == hour){
app.cancelLocalNotification(singleNotification)
break;
}
}
I used Int but it is a Dictionary
