Okay. I'm having some problems getting some code of mine to work.
Here's the procedure I followed as well as the errors I'm getting.
1. I have the original class. It's called BlogController. I like it
enough to use it in a second app.
2. I create the second app and get to the point where I'm ready to add
BlogController.
3. In Interface Builder, I create a class called BlogController. I
give it all the same outlets and actions as BlogController from App #1,
and connect all of the outlets to the appropriate places and
appropriate buttons/menu items to the actions.
4. I tell Interface Builder to create the files for BlogController and
insert them into my app. It does so.
5. I open the first version of BlogController, Command-A to select all,
Command-C to copy, back to the new version of BlogController, Command-V
to paste.
6. When I run App #2, I now get the following errors at runtime:
2002-10-31 01:40:26.571 EspressoBlog[4223] Unknown class
`BlogController' in nib file, using `NSObject' instead.
2002-10-31 01:40:26.656 EspressoBlog[4223] Could not connect the action
getBlogList: to target of class NSObject
2002-10-31 01:40:26.676 EspressoBlog[4223] Could not connect the action
getCategoryList: to target of class NSObject

2002-10-31 01:40:26.678 EspressoBlog[4223] Could not connect the action
getBlogList: to target of class NSObject
2002-10-31 01:40:26.678 EspressoBlog[4223] Could not connect the action
getCategoryList: to target of class NSObject
------
I understand why the 2nd through the last lines are happening -
obviously, NSObject doesn't have any of those actions. What I can't
figure out is why the first line is occurring - why IB is insisting it
doesn't know what this class is! I've tried rebuilding after cleaning
the active target...frankly, I'm fresh out of ideas. Anyone got one?
Thanks,
Phil Ulrich
