pass data between content and menucontroller - ios

Question

I'm having a menuViewController and a ContentViewController using https://github.com/romaonthego/RESideMenu. The MenuViewController contain a list of different leagues retrieved from local database. This contain a league object with following vars leagueId and name. When a league is selected it should send the data to the ContentViewController. However the problem is that the MenuViewController is not presenting the viewController it is just hiding the menuViwController and therefore i can't pass data from menuViewController to contentViewController when a cell with a league is selected. i've therefore tried to save the leagueId to a NSUserDefault key, however this creates a problem when the app is exited, since it wont reset the NSUserDefaults. What is the best approach for such issue? should i rethink it?
pressing cell in menuViewController
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
NSUserDefaults.standardUserDefaults().setInteger(menuArray![indexPath.row].id, forKey: "leagueId")
self.sideMenuViewController.hideMenuViewController()
}

You can achieve this by creating a global class, First create a global class, :-
import Foundation
class User {
class var sharedInstance: User {
struct Static {
static var instance: User?
static var token: dispatch_once_t = 0
}
dispatch_once(&Static.token) {
Static.instance = User()
}
return Static.instance!
}
var leagueId: Int?
var name:String?
}
then store data in the class that you want
class ViewController: UIViewController {
let user = User.sharedInstance
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "showDetails" {
self.user.leagueId = Id
self.user.name = Name
}
}
}
Then retrieve data :-
class ViewController: UIViewController {
let user = User.sharedInstance
mylabel.text = self.user.leagueId
mylabael2.text = self.user.name
}
