在其他ViewController中访问变量Swift

Question

I have a user login to through a welcome screen in my app. Now I want that username to pass on to the other view controllers I have in the rest of the app, however i cannot figure out how. In old C i would have done an #import viewcontroller but that is not working.

I have one LoginVC where I set the username from a regular field

class LoginVC: UIViewController,UITextFieldDelegate {
    @IBOutlet var txtUsername : UITextField!

now I want to show that txtUsername variable in my ActionVC as a regular var preferably in a function - however I have no idea how?

func accessOtherViewController(){
    var userName = LoginVC(txtUsername)
}

Answer 1

 var myCustomViewController: SomeViewController = SomeViewController(nibName: nil, bundle: nil)
    var getThatValue = myTableView.someVariable

Answer 2

You can create a public var to access variables in other view controllers.

At the top of your viewcontroller class add public var name = "saucepan";

You should access this var in other view controllers if you only type the name of the var it will turn green (depending on your color scheme).
