There's one .xib, a DrinkDetailViewController class (.m & .h files) and an AddDrinkViewController class which inherits from DrinkDetailViewController. Both share the same view, which contains a UITextField, two UITextViews, and some UILabels. The DrinkDetailViewController.h declares three IBOutlets as follows:

The AddDrinkViewController re-uses the view for data entry, and I want to re-enable the fields, but only when the view (xib) is used/loaded by the AddDrinkViewController. I looked in the docs for UITextField, but didn't even see a reference to an enabled property. Is this another of those view-within-a-view problems?
The enabled property is defined in UIControl --- the super-class of UITextField . . .
This is a good time for a plug for Xcode's incredibly useful but oft skipped over Class Browser,
the second item in Xcode's Project menu . . .
