从导航控制器中的2个不同父项导航到视图是错误的吗？

Lets say I have 2 parent views in the navigation controller, A and B. A is a list of libraries that when you press on a library it takes you to a view with that library's information (lets call this view C). B is where the user can search for books, and a few levels deeper into B the user can see libraries that hold this book, so here is also a button to pop view C to view library information. Is it acceptable to do this? Maybe I will run into problems doing this? The other option is to duplicate the view but I don't think that is right either.Lets say I have 2 parent views in the navigatio
