title: Totally different views on iPad for portrait Vs landscape ... is this acceptable user interface design?
body: <p>I'm refactoring one of my apps from the iPhone to the iPad and this has resulted in the removal of tabs as I've been able to combine functionality onto 1 screen and use popovers to enable the user to select stuff that previously required a new tab.</p>
  
  <p>I'm basically left with 2 tabs now. One (which is best viewed landscape) shows a map of the world with some overlays drawn on it plus an indication of where you are. The second is a data display with a few graphs which is best viewed portrait.</p>
  
  <p>I note what Apple say about requiring apps to run in all orientations on the iPad, and of course I could do this, and keep my 2 tab bar buttons to switch views.</p>
  
  <p>HOWEVER</p>
  
  <p>In this case, there is 1 view that is best suited to landscape view and 1 view that is best suited to portrait view. Would be be appropriate (or even Apple permissible) UX design to drop the tab bar and switch views on an orientation change instead?</p>
  
  <p>From a user perspective, you wouldn't need to be switching back and forth much, you tend to use the landscape view to change location (if you need to) and then work mainly in the portrait view - so I don't think it would be frustrating and dropping the tabs seems to make more sense to me.</p>
  
  <p>What do you think? Any best practice in these situations?</p>
