Question

is it posible to have navigationcontroller view and a subview on it (or independent view) which not moves when navigationcontroller is pushed or poped? Both views responds to user interaction.

Answer 1

Yes, using container view controllers this is absolutely possible.

1. Create a custom container view controller and add a subview (the view that should not move)
2. Instantiate UINavigationController and add it as a child view controller (using addChildViewController:) of the container view controller from step 1
3. Attach UINavigationControllers‘s view below the subview you added in step 1

After that, you’re done.
