title: How to refer to Cocoa controls located in in the same NSWindow?
body: <p>I have a NSWindow with an NSView and an NSTextField inside.</p>
  
  <p>I'm using Interface builder right now. I have dropped the two controls on the  default NSWindow and subclassed an NSView. I'm implementing the <code>-drawRect</code> method from NSView and I need to access to the content of NSTextField.</p>
  
  <p>How do I refer to the instance of NSTextField from a method inside the NSView ?</p>
