title: How do i move the sprite while the finger is touching?
body: <p>I'm working on a small game to learn more xcode and objective-C.</p>
  
  <p>I want to move my sprite along one axis while i am touching.
  I know how to use SKAction with moveBy, but the sprite stops moving when it reaches the stated distance. </p>
  
  <p>I want the sprite to move untill the touch ends. Currently i'm only moving it along the x axis.</p>
