title: Disable warnings coming from a specific folder
body: <p>I've set up an Xcode project where part of the code (a folder in this case) comes from a svn repository.</p>
  
  <p>The folder is <strong>constantly updated by an external partner</strong> and it contains <code>.h</code> and <code>.m</code> files. In particular, these files are included in the project since set up as <strong>Header Search Paths</strong> and <strong>Library Search Paths</strong> within my Target.</p>
  
  <p>Since, <code>.h</code> files contain a lot of warnings (I receive the <strong>Showing first 200 warning only</strong> message), Xcode does not allow me to show my code warnings.</p>
  
  <p>Based on this scenario, how is it possible to prevent Xcode to show those warnings for that specific folder?</p>
  
  <p>I followed few discussions within SO (<a href="https://stackoverflow.com/questions/965093/selectively-disable-gcc-warnings-for-only-part-of-a-translation-unit/3394305#3394305">Selectively disable GCC warnings for only part of a translation unit?</a>, <a href="https://stackoverflow.com/questions/11841479/turn-off-warnings-coming-from-subprojects">Turn off warnings coming from subprojects</a>) but I haven't found a solution yet.</p>
  
  <p>Thank you in advance.</p>
