Question

I am little bit confused about creating universal application for iOS devices using Xcode 4.3 , later versions (Xcode 4) have separate folder classes for this, but how will we make this using newest version of Xcode?

Thanks in advance

Answer 1

I don’t think this has changed in Xcode 4.3 compared to previous versions of Xcode 4.* , but though you have a doubt refer to my answer below.

If you want to create a new project as Universal App then select Universal in Device Family in below image:

Or if you are trying to convert an existing iPhone or iPad app to Universal app then select Devices as Universal from Target Settings– > Summary Tab, set Devices to Universal:

Hope this helps you.

EDIT:

Let us suppose View Controller name is YourViewController

Let us suppose name of iPad XIB is YourViewController-iPad.xib and iPhone xib name is YourViewController.xib

YourViewController *yourViewController;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) //This is iPad 
{
    // iPad-specific interface here
    yourViewController = [[YourViewController alloc] initWithNibName:@"YourViewController-iPad"  bundle:nil];
}
else // This is iPhone or iPod
{
    // iPhone and iPod touch interface here
    yourViewController = [[YourViewController alloc] initWithNibName:@"YourViewController"  bundle:nil];
}

Let me know if you need more help.
