I have an interesting problem. I have an app that I'm developing that involves photos so screen space is at a premium. Also, using disappearing and reappearing nav / tool bar controllers (like in the camera app) doesn't make sense for me. In a perfect world, I'd use a UITabBar to switch between the 4 main navigational view controllers that my program implements, however I also am going to need space for a toolbar right on top of the tab bar most of the time. These two components take up too much space between the two of them so I need a way to save some space.
That's where I came up with the idea of using a toolbar to implement the functionality of both the TabBar and ToolBar. On the left side of the ToolBar would be the 4 buttons that allow access to my 4 main navigational view controllers. The one that is currently on the window would have it's button depressed. Then there would be a divider, and on the right side of the tool bar would be buttons specific to whatever view is currently on the window.
Anyhow, I'm just wondering if anyone has any clever ideas on how they'd implement this?
