title: How to implement Periscope's heart animation?
body: <p>I want to implement something similar like what periscope does to their live streaming app. To be specific, the countless floating heart emitted when user touch the screen. Is this could easily be achieved by SpriteKit or Cocos2D? Can anyone shed me some lights or , at least, a good starting point.</p>
  
  <p>THANKS</p>
