Hey Daniel -
What you're trying will probably work. IB is issuing a warning because
it sees that MYCollectionView is a subclass of NSCollectionView, and
it knows that NSCollectionView doesn't exist on Tiger. You can either
ignore the warning, create the MYCollectionView in code, or tell IB
that the deployment target for the XIB is 10.5 even though that isn't
really true.
Good Luck -

Hi , List，
I‘m doing some work of downgrading the existing Leopard GUI to
Tiger GUI.
We are using a lot of Bindings and
NSCollectionView ,NSCollectionViewItem in
the current xib.I want to reuse the current the xib in the Tiger
version ,
cause we use binding to control a lot of UI elements dependencies.
So I change the current NSCollectionView's class Identify to my own
class ,
e.g. MYCollectionView. ,which I'm going to implement it with the same
interface of NSCollectionView. However , when I change the
Deployment Target
into Mac OS X10.4.x in the XXX.xib Info panel and save the xib
project . IB
post the error said that NScollectionView is unsupported in the
version
prior to 10.5.
Now I'm confused by the error message , I've already changed all the
NSCollectionView and NSCollectionViewItem's class identity to my own
class .
Why the IB still post me this kind of message? Could anyone give me
some
hint of how to handling this problem? Thank you in advance.
By the way , if this approach is not accessible , does that mean I
have to
recreate all the xib ?
Best Regards ,
- Daniel yi Lin
