title: runtime output objc[69590] when using CocoaPods with 2 projects
body: <p>I created 2 xcode projects "mylib" and "myapp" </p>
  
  <ul>
  <li>the project type of mylib is "iOS -> <strong>Cocoa Touch Framework</strong>" </li>
  <li>and the project type of myapp is "iOS -> Application -> <strong>Single View Application</strong>".</li>
  </ul>
  
  <p>Both of the projects depend on "AFNetworking", so I wrote the Podfile below.</p>
  
  <pre><code>workspace 'myapp'
  
  platform :ios,'7.0'
  xcodeproj 'myapp/myapp.xcodeproj'
  
  target :myapp do
      xcodeproj 'myapp/myapp.xcodeproj'
      pod 'AFNetworking', '~&gt; 2.5.4'
  end
  
  target :mylib do
      xcodeproj 'mylib/mylib.xcodeproj'
      pod 'AFNetworking', '~&gt; 2.5.4'
  end
  </code></pre>
  
  <p>After I run "pod install", I got <a href="https://github.com/everettjf/cocoapods_two_projects_obj69272" rel="nofollow">https://github.com/everettjf/cocoapods_two_projects_obj69272</a> , and build without errors.</p>
  
  <p>But when I run in the "iOS simulator" , lots of warning messages outputs in the console window.</p>
