In a universal binary iPhone/iPad app of mine, users are able to adjust preferences in a view controller that's presented modally. On the iPhone, the settings panel is presented with presentModalViewController:animated:, and on the iPad, I use a UIPopoverController.
I'm having a heck of a time completely isolating the UIPopoverController code away from the iPhone code. Everytime I compile for the iPhone, I get the following error:
dyld: Symbol not found: _OBJC_CLASS_$_UIPopoverController
Referenced from: /var/mobile/Applications/CBB37F87-AA6D-47E2-823A-E259E3268A32/MyApp debug.app/MyApp
Expected in: /System/Library/Frameworks/UIKit.framework/UIKit
This is of course because UIKit on the iPhone doesn't have a UIPopoverController class. Does anybody have advice for how to effectively isolate the iPad API includes from the iPhone code, so I can actually run my code?
