title: Installing Google Maps SDK for iOS via cocoapods causes linker errors
body: <p>I'm trying to install the Google Maps SDK for iOS version 1.3.0 using cocoapods.</p>
  
  <p>Actually the installation process is well succeeded, but when I try to use the framework the app building process returns linker errors, e.g.:</p>
  
  <pre><code>Undefined symbols for architecture armv7:
  "_OBJC_CLASS_$_GMSServices", referenced from:
      objc-class-ref in AppDelegate.o
  </code></pre>
  
  <p>For some reason the linker can't find the framework. My cocoapods version is 0.20.1. XCode 4.6.2.</p>
  
  <p>Besides Google Maps SDK my project has 2 other libraries added via cocoapods.
  Here is my Podfile:</p>
  
  <pre><code>platform :ios, '5.1'
  
  pod 'DTCoreText'
  pod 'MKNetworkKit'
  pod 'Google-Maps-iOS-SDK'
  </code></pre>
  
  <p>Thanks in advance.</p>
