title: Issue implementing Glass Button UIButton
body: <p>I'm a noob to iphone development and i'm having a weird issue while trying to implement Glass Buttons (<a href="https://github.com/hboon/GlassButtons" rel="nofollow">found here</a>).  My build fails because I'm getting an "unexpected @ in program error" inside the MOGlassButtons.m file.  I haven't been able to find anything regarding how to resolve this issue.  Any help is greatly appreciated.</p>
  
  <p>MOGlassButton.m</p>
  
  <pre><code>self.gradientLayer1.colors = @[(id)[MO_RGBACOLOR(255, 255, 255, 0.45) CGColor], (id)[MO_RGBACOLOR(255, 235, 255, 0.1) CGColor]]; //&lt;--"unexpected @ in program error" 
  
  self.gradientLayer2.colors = @[(id)[MO_RGBACOLOR(205, 205, 205, 0) CGColor], (id)[MO_RGBACOLOR(235, 215, 215, 0.2) CGColor]]; //&lt;--"unexpected @ in program error" 
  </code></pre>
