Hey Fabian -
The fact that you cannot connect the custom view's action is a bug in
Interface Builder 3.0. You should be able to apply the connection. The
good news is that this particular bug is already been fixed.
When you set the 'custom class' in interface builder, all that is
happening is that a piece of meta-data is being attached to the object
that says "At runtime make this an instance of X instead of Y." The
change only happens at runtime though. So, when you start with a
custom view in IB, and change it's custom class to "MyView", for all
of design time, the object is still an instance of "CustomView". It
only becomes a "MyView" at runtime. The same goes for NSButton's, if
you change the custom class of an NSButton to a "MyButton", for the
entire time that the button is in IB, it is a "NSButton", only at
runtime does it become a "MyButton."
The benefit of applying the custom class information of "MyButton" to
an NSButton, instead of a custom view, is that you can still use the
button inspector in IB to set your button's inherited properties.
You'll also be able to work around the action connecting bug, and in a
couple of minutes, you'll probably also realize that you need to set
the custom class on your button cell too. With an NSButton instead of
an NSCustomView, this will all be much easier.
Good Luck -

With Interface Builder 2 it worked without any problems to use a
Custom View and change its class to my NSButton subclass...
I already tried to change the class of an NSButton in Interface
Builder 3 to my subclass, but unfortunately it does not change its
appearance accordingly. It seems not to change the class of the
button :-(

As far as I can tell, CustomView is only suitable for subclasses of
NSView. NSButton is further down the line of inheritance and IB
doesn't work with it like it does normally ...
What about, starting with NSButton and specifying the Class value
as your own subclass?
