How to make delete animation like Notes app

Question

I want to make an animation, like the deleting a note in iPhone Notes app. But here I want to do it for Tabbar. So deleting a view (something shows in a view) will swoop down in a delete tab bar icon. Say, I have favourite tab bar item, so adding something in the favourite will swoop down the view in the favourite tab bar item.
