Hi everyone, I've been working on a personal project, which starts with one view controller. I have add multiple views into it and call each view by using this method self.view = self.newView; It seems to work fine and I don't have to worry much about sharing data since all the views are in the same controllers. Recently, I just become interested in using Navigation Controller or Tab Bar Controllers to navigate the views. However, from most of the tutorials and the books I found, they all seem to have a view controller for each view that needs to be hooked to the navigation controller. So I'm just wondering if it is possible to use either navigation or tab bar controller with just one view controller that contains multiple views in it? Thank you for the guidance.
