Transform from ios6 to ios7 - ipad

Question

I have an universal app where I successfully upgraded the iPhone component to ios7.
The ipad component however is not running anymore. I get the following error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UISplitViewController tabBar]: unrecognized selector sent to instance 0x8d9eef0'
I have no idea what happened. I did not touch the ipad side of things whatsoever.
I am running: 11A4449d build and 5A11365y build for x-code on a mac machine.
After this code the error happens:
- (void) awakeFromNib {
[super awakeFromNib];
// whenever I come out of a storyboard, I make myself the delegate of any splitview I am in
self.splitViewController.delegate = self;
}

Answer 1

In this method: I set the selected image on a tab bar for the iPhone.
But did not realise that the iPad will not like it. So I put a selective statement (if !iPad) around it to fix it.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
BOOL piPad = (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad);
if (!piPad)
{
// **************************************************************************************************
// Assign tab bar item with titles and selected images
UITabBarController *pTabBarController = (UITabBarController *)self.window.rootViewController;
UITabBar *pTabBar = pTabBarController.tabBar;
UITabBarItem *pTabBarItem0 = [pTabBar.items objectAtIndex:0];
pTabBarItem0.title = #"List";
pTabBarItem0.selectedImage = [UIImage imageNamed:#"tabBarList_30x30_selected"];
pTabBarItem0.image = [UIImage imageNamed:#"tabBarList_30x30.png"];
// **************************************************************************************************
}
return YES;
