Universal app question

Hello,
I have read the documentation for universal apps and came to the conclusion that the following has to be done in order to get an app run on both iPad and iPhone/iPod touch:

1. I have configurated my iPhone app using Xcode’s Upgrade Current Target for iPad.
2. In the AppDelegate, I have seperated the code to be used when running on the different devices as follows in the .h file:

Code:

@interface AppDelegate : NSObject <UIApplicationDelegate, DataAccessDelegate, CLLocationManagerDelegate> {
    UIWindow *window;
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200 
	iPadViewController *viewController;
	RotatingTabBarController *tabBarController; 
#else
	UITabBarController *tabBarController;
#endif

and in the .m file

Code:

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200
	IPADstartViewController *myViewController;
		myViewController = [[IPADstartViewController alloc] initWithTabBar];
#else
	startViewController *myViewController;
		myViewController = [[startViewController alloc] initWithTabBar];
#endif
	
	localNavigationController = [[UINavigationController alloc] initWithRootViewController:myViewController];
	
	[localControllersArray addObject:localNavigationController];// to the array of controllers
	[localNavigationController release];// release since we are done with this for now
	[myViewController release];

My problem is:
It seem to work when chosing the iPad simulator 3.2 but if I chose the iPhone simulator 4.0 I get problems. The iPhone simulator is opened up but it tries to open up a view with a popovercontroller and is off course crashing. So - the question is: is this the proper way to seperate code in the appDelegate?

Thanks in advance!

Thanks for the answer! OK, I will look into the documentation again. I suppose I missunderstood that part. Thanks!

Yes I found it - thanks for the hint! It works!

Hello,
yes I noticed that and it makes sence. Now, I have an app running either on the iPhone or the iPad. If I (in the simulator) pic the iPad simulator it is running using the iPad simulator. If I pic the iPhone simulator, it is running in the iPhone simulator. I have different viewControllers for the different devices, but the functionality classes (like parsing, data access etc) do the share. In the appdelegate i do some choices depending on the current device.

Is this the way to think when creating Universal Apps?
