title: Dependency injection framework for Cocoa?
body: <p>Interface Builder can be used for basic dependency injection in a Cocoa app, but is anyone aware of more complete dependency injection frameworks for Objective-C/Cocoa for when you don't want to instantiate objects in a NIB file?</p>
  
  <p><strong>Edit</strong></p>
  
  <p>To clarify, I recognize that IB can be used for basic DI, but I'm looking for a framework with more complete functionality, including separate production and testing configurations, along the lines of Groovy or Springs.</p>
