IOS Faux yy Live Heart Animation & Fireworks Animation

YY Live to praise the effect.

Fireworks Demo Effect

will continue to update the animation related small effects point I download the project-it feels good to point a star

These two small effects are seen on a platform, and the finishing study is put on my github. For your own learning, and provide to interested small partners.
