An animation practise demo,See it on Dribbble
##Asset I used...
I used Swifticons in main UI for its subtle color and shape.
##Why I Do This?
As a motion designer,I begin to learn some code.
When I saw the Lush App,I'm very interesting in its tabbar's design.The Square moved in tab bar and changed color,I like the wonderful effect!That's why I make this demo.
In this demo,I try to use CABasicAnimation/POP Animation/Animatewithduration to make effect better.
This is the effect in Xcode
Sorry for my poor code skill.I'm keep learning,welcome for suggest.
P.S Special Thanks to AlienJunX,he is always supporting me.
