Transition model for "Add item" in iOS

I‘ve been exploring Principle for a little over an hour now, and I really like what I see. To understand it better, I tried to replicate something I built for DoNext with Origami (https://vine.co/v/O9OQnqv5I7A).

And the result was ridiculously easy to replicate. Bear in mind that there’s still some transitions to be added for the nav bar itself.

About the shot:

I’ve never been a big fan of the excessively long animation time taken to invoke an entire screen when you tap add to a TableView in iOS. This is especially frustrating since the view makes the keyboard look like a part of the screen when it’s clearly a separate component.

This is an attempt at making a leaner animation view. I’d be curious to hear what you think and if you know of any apps that are doing anything similar.
