How to implement Spotify-like iOS app sidebar feature

Question

I've already implemented a sidebar like that in Facebook/Path apps with ECSlidingViewController but I've noticed that Spotify app it's a bit different and has a very slick effect. The sidebar is not already full visible but it slides and show the icons as more as you swipe with your finger. How to animate the sidebar in this way?

Here an image for a better explanation.

Answer 1

Take a look at MMDrawerController https://github.com/mutualmobile/MMDrawerController

It has nice sample app and allows custom sliding effects, including the one you are looking for

Answer 2

There are many such libraries available to implement the behaviour you have asked for. I would recommend ECSlidingViewController since its easy to use plus it supports StoryBoards:
