Hi,
In my app I have a view controller that has its own navigation controller. But sometimes I need to call it from another navigation controller. When I do so everything is fine but when I want to open a view controller from its own navigation controller again, the view itself is not being displayed. viewWillAppear method of a view controller is being called but what I see on the screen is a totally white view and a navigation bar without the name of a view controller.
Why does it happen and how can I fix it?
