Pass Data from Tableview to Tab Bar View Controller in Swift

Data pass tableview cell to tab bar view controller in Swift

In your code

let ImageStoryboard = UIStoryboard(name: "Main", bundle: nil)
let ImageController = ImageStoryboard.instantiateViewController(withIdentifier: "IMAGESCOL") as! ImagesCollectionViewController
ImageController.RecivedData1 = media.bannerImages

These codes do nothing is expected, because you declare an ImageController, but you don't use/present it.

So, according to the context, I assume that you have a UITabBarController in Main.storyboard, and the UITabBarController has two UIViewController, and one is ImageController. If I were right, you could try codes below:

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let tabBarController = storyboard.instantiateViewController(withIdentifier: "IMAGEVID") as! UITabBarController

// You should access the `imageController` through your `tabBarController`, 
// not instantiate it from storyboard.
if let viewControllers = tabBarController.viewControllers, 
   let imageController = viewControllers.first as? ImageController {
    imageController.recivedData1 = media.bannerImages
}

navigationController?.pushViewController(tabBarController, animated: true)

Another suggestion is you should use camel case to name your properties. For more details, you can refer to this style guideline.

How to pass data between view controller and the tab-bar's view controllers using segue?

I got my answer

    @IBAction func submitButonTapped(_ sender: Any) {
            performSegue(withIdentifier: "homePage", sender: self)
    }
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        let barViewControllers = segue.destination as! UITabBarController
        let destinationViewController = barViewControllers.viewControllers![0] as! ViewControllerB
        destinationViewController.containsData = Data
    }

How to pass data from view controller to first tab of tab bar controller

First of all you are doing two different things

1. there is a segue between DiscoveryNewsViewController and tabbarController

2. You are pushing tabbar controller like this

   let DVC = tabBar.viewControllers?[0] as! NewsViewController
   //this is not required as it will always open UIViewController at Zero index so comment this
   //tabBar.selectedIndex = 0
   let image = sneakersnews[indexPath.row].image
   DVC.getImage = image
   let news = sneakersnews[indexPath.row].news
   DVC.getNews = news
   self.navigationController?.pushViewController(tabBar, animated: true)
   

Please read commented lines in above code

So you cannot do both above mention points at a time because a segue connection is already pushing your TabBarController and your self.navigationController?.pushViewController is also pushing TabBarController.

SOLUTION:-

1. Just embed DiscoveryNewsViewController in navigation controller

2.Remove segue connection between DiscoveryNewsViewController and tabbarController

Pass data to Tab Bar Item (ViewController)

If you configured correctly such storyboard, you should get the reference to the UITabBarController through prepare(segue), doing so:

private weak var tabBarViewController:UITabBarController?

// be sure to add prepare inside your segue manager (the container in this case)
override public func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    self.tabBarViewController = segue.destination as? UITabBarController
}

besides you may want to declare an enum to have a clean access to the embedded view controllers:

enum TabType:Int {
    case blue
    case green
}

thus you might define a function for injecting the selected indexPath, doing something like:

func inject(indexPath:IndexPath, into tab:TabType) {
    if let greenVc = tabBarViewController?.viewControllers?[tab.rawValue] as? GreenViewController {
        greenVc.selectedIndexPath = indexPath
        tabBarViewController?.selectedIndex = tab.rawValue // this will auto select the TabType viewcontroller
    }
}

finally whenever you have to change the current selection, you may call inject with the new indexPath:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    self.inject(indexPath: indexPath, into: .green)
}

Note

Call instantiateViewController means making a new "fake" view controller, which is a wrong approach, since you already have it embedded in your UITabBarController.viewControllers

pass data from tabbar controller to view controller in swift and xcode

Take a look at the documentation for the tab bar controller, in particular the viewControllers property.

That property is an array of UIViewControllers, in the order they appear in the tab bar, so you can pick the one you need (viewControllers[0] from your screen shot), cast it to your specific view controller subclass and then pass it your data.

Pass data from tableview to view controller in tab bar in Swift

Try this

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if let destination = (segue.destination as? UITabBarController)?.viewControllers.first as? EventViewController {

        destination.event = events[(tableView.indexPathForSelectedRow?.row)!]

    }
}

Pass data from tableview to tab bar view controller in Swift.

I have found a solution:

    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
      }
    }

Easy explanation: You need to get to your Tab bar controller and pick his view controllers. It normally has two, so you can pick the first. After that, define which class it belongs to, and you can pass your data just as you did before.

Pass Data From ViewController to TabBarController

The segue destination is the tabBar access it then you can get the first vc and pass the data

let custMainVC = segue.destination as! UITabBarController
let res = custMainVC.viewControllers!.first as! CustomerMainViewController
res.tempName = self.emailTextField.text!
