Hey,

I have started looking at Key Value Observing but I'm having trouble working out how to observe the changes within an Array.

Is there some place I can find example code on this to help wrap my head around it?

Cheers
Alex Mills

You can use KVO to call a method when the selectedObjects value changes. Check the KVO documentation and the archives for more details.
