Question

I am trying to conceive of a way in which I can float a view over top the tab bar. This would essentially cover it. I’m not sure how to go about this. If the tab bar is itself a subview of another controller, then this would seem easy, but from what I understand you cannot really do this without “abusing” the view controller methodology (i.e. addSubview: tabbar.view or something similar).

Basically, there is limited space on an iphone screen and the tab bar is the navigation but at times I want to use that space to show information briefly. If the tab bar is my root controller, I would think this is not possible.

I’ve read other posts on here that suggest using the setHidesBottomBarWhenPushed but I’m not using a nav controller, and I also want to dynamically control when the bar gets hidden or covered by another view, so I can move that new view out of the way when desired and show the tab bar again.

Any other suggestions to point me in the right direction would be appreciated.

Answer 1

I would suggest the following.

UIView
   |
    --UIView (this will hold the tab bar controller)
        |
         -- Tabbar controller
   |
    --Full Screen View

So basically the tab bar is enclosed in a UIView. This is added to the main UIView. When you want to display full screen you can add that view to the main UI view. Thus there would be no need to hide/unhide the tab bar.
