body: <p>So my app will no longer compile now that I updated to iOS 7.1, here's the error</p>
  
  <pre><code>CCDirectorIOS.h:109:16: Redefinition of '__ccContentScaleFactor' with a different type: 'CGFloat' (aka 'double') vs 'float'

  <p>With cocos2d v2.</p>
  
  <p>I tried updating to cocos2dv3 but I have to change 90% of my code it seems. Is there a way I can somehow update cocos2d to compile with iOS 7.1? </p>
