cannot find Array Controller in Interface Builder

I'm just starting to use core data in my iphone app. I have created my Entity (measure) with 2 property (date, value). According to the tutos I'm reading, I then need to create an Array Controller in Interface Builder. The thing is... I cannot find it in IB. I开发者_StackOverflows there something to configure to have this type of controller in the list ? Thanks, Luc

NSArrayController is not available in iOS, only on the Mac.
