ios - Change view controller when user exits app -

-

hey trying make whenever user presses home button , try returns app, returned initial view controller. there can write app delegate work?

i have tried call function in applicationdidbecomeactive function:

let storyboard = uistoryboard(name: "main", bundle: nil)     let vc = storyboard.instantiateviewcontrollerwithidentifier("homevc") as! uiviewcontroller     self.window?.rootviewcontroller?.presentviewcontroller(vc, animated: true, completion: nil)

but error saying view not in hierarchy.

any appreciated!

you want implement applicationdidbecomeactive method of app's delegate, , programmatically perform segue or dismiss current view controller, depending on navigation setup.

your users might not forced navigation though. general assumption can resume left off.
