Thanks for jumping in here, Quincey. Hiding the tab does NOT seem like a reasonable way to approach this. > According to the UITabBarController documentation, “You should never access > the tab bar view of a tab bar controller directly.” > Darn - I didn't see that. That said there are ways through the appearance proxy to access some of the UITabBar properties. I guess the ones exposed are the only ones that are official usable in that context then. > In any case, it’s the view *controller* that controls the geometry of the > views it manages, so if the tab bar controller isn’t expecting the tab bar > to be hidden, it likely has no way of “reclaiming” the tab bar view’s real > estate without its own API for this. > I had the following idea for a work-around: Wrapping the controllers that go into the UITabController with a UIViewController that has a child view controller. And then I could adjust the size of the child view controller (and thereby hopefully the whole view controller stack). But I haven't tried this yet. I am also quite sceptical how well this works with the UINavigationController in the mix. > So that leads to the question of why the view controller (apparently) has > no API for properly hiding the tab bar.

Of course there would be a way to leave the view controller. And yes - the UITabController is a the root of the navigation. It's more than unfortunate I have to go down the tab bar hiding route - but at this stage there isn't really a way around it. (Ideally I would present a modal controller - but cannot for reason beyond my control. long story) Thanks for your input! cheers, Torsten _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
