How to add a notification? - swift

Question

I want to add a local notification in my project. In the DetailViewController, I have two labels with date and hour.
Is it possible to add a notification based on this date and hour? If yes, can you explain how to set it?
Code:
DetailViewController :
import UIKit
class DetailViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
// MARK: - Outlet
#IBOutlet var imageProfilo: UIImageView!
#IBOutlet var labelNome: UILabel!
#IBOutlet var pillsTable: UITableView!
// MARK: - Variabili
var profilo: ProfiloModel!
// MARK: - Metodi standard del controller
override func viewDidLoad() {
super.viewDidLoad()
pillsTable.dataSource = self
pillsTable.delegate = self
imageProfilo.layer.cornerRadius = 30
DataManager.sharedInstance.detail = self
if let test = profilo {
//title = profilo!.nome
labelNome.text = profilo!.nome
imageProfilo.image = profilo!.immagine
if profilo!.immagine.size.width > profilo!.immagine.size.height {
imageProfilo.image = UIImage(CGImage: profilo!.immagine.CGImage, scale: 1.0, orientation: UIImageOrientation.Right)
} else {
imageProfilo.image = profilo!.immagine
}
} else {
if !DataManager.sharedInstance.storage.isEmpty {
profilo = DataManager.sharedInstance.storage[0]
//title = profiloSos.nome
labelNome.text = profilo.nome
imageProfilo.image = profilo.immagine
if profilo.immagine.size.width > profilo.immagine.size.height {
imageProfilo.image = UIImage(CGImage: profilo.immagine.CGImage, scale: 1.0, orientation: UIImageOrientation.Right)
} else {
imageProfilo.image = profilo.immagine
}
} else {
return
}
}
}

}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! PillsCell
var terapia = profilo.therapyArra[indexPath.row]
cell.nomeMedicina.text = terapia.nomeMedicina
cell.data.text = terapia.data
cell.ora.text = terapia.ora
cell.dosaggio.text = terapia.dosaggio
return cell
}

You should use UILocalNotification. Use your date and time to create a NSDate object and then setup your notification like this:
let notification = UILocalNotification()
notification.fireDate = ... // Add your date here
notification.alertBody = "Alert alert alert!!!"
UIApplication.sharedApplication().scheduleLocalNotification(notification)
Handle the notification in your AppDelegate by overriding the didReceiveLocalNotification method:
func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {
println(notification.alertBody); // "Alert alert alert!!!"
}
