I am setting up some user preferences to allow the user to customize the side menu. I have the customization items set up on the preferences VC with a UISwitch for each item. I found that when the item is changed on/off the new setting is not realized until the rootViewController is reinitiated. To try to fix this I have a function that presents an alert. The alert contains code to perform the re-instantiation of the root controller.
The problem I had at first was the "contentViewController" for the side menu was hard coded so when the alert code ran, the contentViewController/Home VC was shown instead of staying on the preferences VC. To remedy this problem I created a variable "thecCntentViewController" to hold the ID of the "contentViewController". I set thecCntentViewController to "Preferences_VC" and that now keeps the Preferences VC on the screen when the UISwitch is changed.
I have everything working except for one glitch. The NavigationBar disappears when the alert code runs. The Preferences VC is imbedded in a NavigationColtroller. Can you tell me what is need to change to keep the navigationBar from disappearing?
`func presentAlert()
{
let alert = UIAlertController(title: "Configure the Side Menu",
message: "The Side Menu needs to be reloaded after modifying key preferences.",
preferredStyle: .alert)
let confirmButton = UIAlertAction(title: "OK", style: .default) { (_) in
thecCntentViewController = "Preferences_VC"
let sideMenuController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "rootController")
UIApplication.shared.keyWindow?.rootViewController = sideMenuController
