Sequentially presenting a uninterrupted series of Modal View Controllers

Question

I have view controller which does some animation action for a specified time with supplied data and then pops.

Now I want to use this very modal view controller with a collection of data. So each get presented after the earlier ends sequentially.

I can't figure out were to trap the end of the earlier cleanly so the users sees a series of uninterrupted sequence of modal view controller.

I tried viewDidDisappear in child and viewWillAppear in parent. But I always end up with the parent view controller not the uninterrupted continuous sequence of modal view controllers I really want to see.
