title: iPhone - Objective C - Nimbus compiling errors when adding NIAttributedLabel module
body: <p>I'm switching to Nimbus in order to replace Three20 in my project.<br>
  When I added AttributedLabel module to the project, I see 24 compile errors.<br>
  This is one of them:<br>
  Do you know how to fix it?<br>
  <strong>(When I remove AttributedLabel from my project, I can compile the project.)</strong></p>
