Re: Runtime error with ABPeoplePickerView

Hi Adam - remember that objects don't contain code. They are simply the 
data that the code will operate on, and an identifier that tells the 
Obj-C system which code to use.

When you instantiate the object in InterfaceBuilder, it has the 
ABPeoplePickerView object's code available to it, so you can test the 
interface with no problem.  When you instantiate the object in your 
app, it's failing to find any class with that name.

I suspect that you need to add the "AddressBook.framework" to your 
project.  As Cocoa developers, it's easy to fall out of the habit of 
making sure we have the "right libraries" in our projects, because so 
much is included for free as a descendent of Cocoa.framework. 
AddressBook, I believe, needs to be added separately.
