The .NET Addict
I've been following Kevin Hoffman's adventures in Cocoa for a little while now. He's a .NET developer who after attending one of Apple's Leopard Tech Talks recently decided to try his hand at Cocoa.
A couple of days ago Kevin posted on NSUndoManager and how great he thought it was. Looking at Kevin's code, I made a suggestion that he perhaps use the method:
-addObserver:toObjectsAtIndexes:forKeyPath:options:context:
to make the code a little simpler, and then perhaps even wrapping this in a Category on NSArray for further ease of use. Today, he posted a new article about just this. Thanks Kevin!
I've only been developing in Cocoa myself for a little over a year, so I wish you continued luck with the experiment.
