badgeValue

Tabs have a property named badgeValue that displays text in a red circle in the upper-right corner of the tab, like the number badges on the Mail or Messages apps. Set the badge value to '3' for the tab variable you just set. Note: badgeValue must be an NSString!

I know that I have to declare badgeValue as an NSString, but after that I'm stuck...If someone could point me in the right direction id appreciate it.

badgeValue is simply a property of the UITabBarItem you just created. All you need to add is:

tab.badgeValue = @"3";

Which access the badgeValue property of the UITabBarItem.
