Remarks
Application developers who wish to implement state restoration would use this method in the following manner:
[Adopts ("UIViewControllerRestoration")]
class MyUIViewController : UIViewController {
[Export ("viewControllerWithRestorationIdentifierPath:")]
static UIViewController FromIdentifierPath (string [] identifierComponents, NSCoder coder)
{
var sb = (UIStoryboard) coder.DecodeObject (UIStateRestoration.ViewControllerStoryboardKey);
if (sb != null){
var vc = (MyUIViewController) sb.InstantiateViewController ("MyViewController");
vc.RestorationIdentifier = identifierComponents [identifierComponents.Length-1];
vc.RestorationClass = Class.GetHandle (typeof (MyViewController));
}
}
}
