title: how to build ios framework to support i386 and armv7
body: <p>I need to build dynamic library as framework. I have building settings as follows: </p>
  
  <pre><code>ARCHS: armv7 armv7s arm64 i386 x86_64
  ONLY_ACTIVE_ARCH: NO
  VALID_ARCHS:  arm64 armv7 armv7s x86_64 i386
  </code></pre>
  
  <p>I built target for ios device,  and used lipo -info to check the architectures, the result is :</p>
  
  <pre><code>Architectures in the fat file: dyl are: armv7s armv7 arm64 
  </code></pre>
  
  <p>So, does xcode can not build for both i386 and arm? </p>
