IB in Xcode 4 not creating ivars

Question

I'm not able to create ivars for my outlets in Interface Builder. I follow these steps:
Open the header file in the Assistant Editor
Ctrl-Drag from a UILabel in the view to the header after the @interface line
When the popup appears, select "outlet" and give it some name, eg myLabel
After this only the property is created. IB never creates an ivar. Am I doing something wrong? I am on Xcode 4.2 and iOS SDK 5.
From Apple's documentation:
You can choose to make the outlet an instance variable or a property.
How?

If I understand your question correctly, you would like to create an IBOutlet instance variable by <Ctrl> dragging a control.  If you drag to the section of the interface declaration that contains instance variables (between the braces), Xcode will create an instance variable. If you drag to the section of the interface declaration that contains properties, Xcode will create a property.
If you drag to create a property, Xcode will synthesize the property.  Explicit instance variables are not necessary for synthesized properties.
