I'm trying to slide some (custom) tab-like buttons into view. I don't want them all to move at the same time. Also, they shouldn't move one at at time (where one slides after the other finishes).

I want each button to begin sliding slightly after the previous. Preferably it would happen on a curve but just a fixed .1 second offset would be alright too.

Monotouch or Obj-C code is fine. I'm thinking there is something in the APIs for animating groups of items like this. Hopefully, at least...
