passing data from one tab controller to another in swift

Question

My application has three viewController associated with three tab of tabBar. I want to switch from 1st tab to 3rd tab and pass some data from 1st view controller to 3rd view controller. I can't do it with segue, because segue create navigation within the selected tab. That is not my requirement. I want to switch tab in tabBar and pass some data without any navigation. How can i do it ?

Answer 1

you can use this code : Objective C

[tab setSelectedIndex:2];

save your array in NSUserDefaults like this:

[[NSUserDefaults standardUserDefaults]setObject:yourArray forKey:@"YourKey"];

and get data from another view using NSUserDefaults like this :

NSMutableArray *array=[[NSUserDefaults standardUserDefaults]objectForKey:@"YourKey"];

swift

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
      if segue.identifier == "toTabController" {
        var tabBarC : UITabBarController = segue.destinationViewController as UITabBarController
        var desView: CaseViewController = tabBarC.viewControllers?.first as CaseViewController

        var caseIndex = overviewTableView!.indexPathForSelectedRow()!.row
        var selectedCase = self.cases[caseIndex]

        desView.caseitem = selectedCase
      }
    }
