How to Add UITabBarSystemItemContacts in StoryBoard

Without StroyBoard we use initWithNibName Method to add System Icons to Tab Bar Controller. I found the sample below

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

if (self) {

// Custom initialization

self.tabBarItem = [[UITabBarItem alloc]initWithTabBarSystemItem:UITabBarSystemItemContacts tag:1];

}

returnself;

}

But if I am using StoryBorad, Under Which Method I have to implement this instead of initWithNibName since there is no nib files. Please help me if there any sample.

Thanks
