1.) start Xcode
2.) choose New Project

han,
by any chance would you be talking about NSThread? You want to break
a process off into another thread to complete your calculation then
notify your application when it is completed. This will not hold up
the UI while doing the calculation.
I am not sure how to implement it as I

You can implement copying of a view by archiving and immediately

Something like this (written on the phone, don't expect this to parse
