title: -ObjC Flag in Xcode Issue
body: <p>I am trying to build a simple iPhone app that calls several static libraries.
  However, it seems when I include the linker flag "-ObjC" and "-all_load" (as I need to for one library), it causes the linker error:</p>
  
  <pre><code>ld: duplicate symbol
  _OBJC_METACLASS_$_ASIFormDataRequest in /Users/XXXXX/Projects/AppName/Dependencies/Library1/lib1Kit.a(ASIFormDataRequest.o) and /Users/XXXXX/Projects/AppName/Dependencies/Library2/lib2Kit.a(ASIFormDataRequest.o)
  </code></pre>
  
  <p>When I remove the flag(s), the linker errors above disappear, but I get:</p>
  
  <pre><code>-[UIView height]: unrecognized selector sent to instance 0x13fe90
  </code></pre>
  
  <p>Has anyone seen this error and how it is related to -ObjC and/or -all_load?
  I am at a loss, so any help would be appreciated.</p>
  
  <p>Thanks,
  Brett</p>
