title: iOS: cocoa Pods: How do I add a new dependency to an existing pod?
body: <p>I have juuuust started with Cocoa Pods.</p>
  
  <p>I have this workspace now after initially experimenting and getting AFNetworking successfully connected via <a href="http://www.raywenderlich.com/12139/introduction-to-cocoapods" rel="noreferrer">this Ray Wenderlich tutorial</a>.</p>

  <p>I want to now add in more dependencies like core-plot specifically.
  I found <a href="https://github.com/CocoaPods/Specs/commit/fb2808a1c0fc5ac23e1a5e85e02039f40bde75fa" rel="noreferrer">this link to a 'PodSpec' of Core-Plot</a></p>
  
  <p>Problem is, I have no idea how to further implement this...
  Anyone have a quick run-down of what to mod and what commands in terminal to run?</p>
