我在LocationVC ViewController上有一个变量“ NameofCircle”，并且在此Controller上有变量CName，我想通过popToViewController将CName值传递给LocationVC Controller。我尝试了下面的代码，但没有得到结果。

let viewControllers = self.navigationController!.viewControllers
    for aViewController in viewControllers
    {
        if aViewController is LocationVC
        {
           let Location = LocationVC()
            Location.NameofCircle = CName
    _ = self.navigationController?.popToViewController(aViewController, animated: true)
            }
}
