Question

I have converted an iPhone application using the wizard like thing in XCode into a universal app.

It builds fine but obviously looks a bit rubbish in some areas 🙂

I need to load nibs according to which device is being used. I dont wish to create my view controllers using initWithNib as I already have code to create the controllers with some data (initWithMyLovelyData) which doesnt do anything to do with nib loading.

I know to find out the device you use UI_USER_INTERFACE_IDIOM() so I tried overriding the initWithNibName within the actual view controllers themselves, assuming they get called internally somehow. But it’s not working as I guess I am unsure of the syntax.

I have tried

if(ipad..) self = [super initWithNibName:@"MyIpadNib" bundle:nibBundleOrNil];

And that doesnt work :/

EDIT – I know I have massively edited this, made my question a bit more specific after doing some more research – apologies!

Answer 1

EDIT: @Adam’s answer below is the correct answer.

To determine which nib to load, do the following, and scrap your initWithMyLovelyData method and use a property to set the data. You should be able to easily move all your init code into the property setter method.

MyViewController *viewController;

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    viewController = [[MyViewController alloc] initWithNibName:@"ipadNIB" bundle:nil];
} else {
    viewController = [[MyViewController alloc] initWithNibName:@"iphoneNIB" bundle:nil];
}

viewController.myLovelyData = someData;
