iOS UI - App Store Explore section Transition

Question

I was wondering if this nice master-detail transition where you click on the tableView cell and it expand to disclose the detail , with the cell's label being the navigation bar title is an interface which is part of the SDK object library or it is a customised one?

Answer 1

This is a custom transition between ViewControllers. There's a nice example of a few transitions (including this one) in this library.

Of course you'll need to add the tableview etc' but this is a great place to start.

Answer 2

I've tried few things but so far this is the best option I could think of. Animating the frames of all the visible cells and making use of childViewController is how I achieved it.

Would be nice to know any other possible solution and ultimately to know how Apple did it!
