iOS - Folder animation in application

Question

How do I create a folder-like animation in my app? I want to do something like the any.do list in terms of animation. I tap on a title, and all the info below scrolls down, and a new info appears (like folders or accordion).

What is the best way to do this?

Example:

Title
text 1
text 2
text 3

tap on title ->

Title
new text below title
text 1
text 2
text 3

Here's what it does:
