title: File Type of sourcecode.cpp.objcpp in xcode
body: <p>Ok so I wanted to play around with CCBlade <a href="https://github.com/hiepnd/CCBlade" rel="nofollow">https://github.com/hiepnd/CCBlade</a>  and in the installation files it mentions something about changing the file type to sourcecode.ccp.objcpp and this is first time I have heard about this. here is the text : </p>
  
  <pre><code>"USAGE NOTICE:
  - CCBlade.m, TouchTrailLayer.m and all .m file that use CCBlade or TouchTrailLayer should
  have the File Type of sourcecode.cpp.objcpp (right click .m file in Xcode go to first tab and under
  File Type drop down list choose the right option)"
  </code></pre>
  
  <p>could someone tell me how exactly I can do this in xcode 4</p>
