Hey Charles -
I would bet that IB is actually reading your header file just fine,
but that you're expecting to see a class list somewhere in IB 3.0 like
you did in IB 2.0. Interface Builder 3.0 doesn't have a class list. If
you select an object in your document and then use the custom class
slice of the identify inspector (command+6), you will see that you set
the custom class with a combo box. You can drop down the combo box to
see a list of all class names that IB knows about that are valid
subclass choices for the object you selected. If you had selected an
instance of NSObject, this list would show you all of the classes that
IB knows about.
Another clue that IB is finding your class files correctly is the
little green/yellow/red dot in the bottom left corner of the main nib
window. That icon has a tool tip and should display the name of your
project. If the light is green, and the name of your project is
showing up next to the light, then IB is automatically reading all of
your class files from your Xcode Project.
Good Luck -

My class simply does not appear in the MainMenu.nib file, it's like
IB doesn't detect anything from the .h file after the parsing.
Any other clues ?
Thank you

I am fairly new to Cocoa and IB but I have background in other
programming languages. I undertand the MVC Concept and I have a hard
time adding my classes created in XCode in Interface Builder 3.0
under
Leopard.
I have read the Apple "Cocoa Application Guide" and the "Interface
builder user guide". Every one of them tells me that IB3 should be
smart enough to monitor the changes in XCOde and add the appropriate
classes in IB, but it just doesn't, even with a newly created
project.
It does not work either if I use the File->Read Class file menu, IB
does nothing, no errors, no console logs, nothing happens.
Same thing happens if I try to drag the .h file from the Xcode
project
to IB.
I have lost a lot of time on this simple task, can anybody help me
on
this ?
Here is what I am trying to do:
-Create an empty "Cocoa Application" Project in Xcode 3
-Add a file named "AppController.h" which is a sub-class of NSObject
- Ignored:
-Add 2-3 outlets to AppController
-Define an action
-Add the class definition to IB 3.0
Here is the AppController.h content:
#import <Cocoa/Cocoa.h>
@interface AppController : NSObject {
IBOutlet id imageView;
IBOutlet id getImageButton;
}
- (IBAction) getImage:(id)sender;
@end
After you have introduced the new interface to IB3 from "Read
Class" or dragged the interface header to IB3, then go an drag a
new Object from the Library to the MainMenu.nib window. Open
identity inspector on that Object, there you can select your Class.
You can read more about this new way in the "Connections and
Bindings" section from the "Interface Builder User Guide".
