NSTextField black outline, not drawing in background thread when in a custom NSControl?

Hey All - quick question, I have a custom search NSControl that I attach an NSTextField onto. I can't figure out why the NSTextField isn't drawing like normal (cursor blink), the cursor is solid black. My control overrides some mouse methods as I change parts of the control when mouse over etc. Th

Do you have an alternate image as well? I believe it's both or nothing. No ... but 1. all the other buttons in my GUI with push-on / push-off work just fine without an alternate image, and 2. the doc says "A button’s image is displayed when the button is in its normal state, or all the t

Re: What is the best way to call parent view controller methods from within child view controller?

You can create an ivar in class B that refer to class A instance. Set that ivar, when class B instance is created. So, you can call the methods in class A by using that instance, without searching through the view controllers array. Besides, you can also change the title before class B is pushed.

NSOpenGL Full Screen

Okay, I'm feeling a little foolish. I've been so focused on iPhone stuff for the last year and a half that I either didn't notice or just plain forgot that NSView now has a method for displaying in full screen mode. It certainly makes the whole process much easier. I've updated the old NSOp

First, a bit about terminology. What you are talking about is not observing child entities. You wish to observe related instances (NSManagedObject or subclass thereof). The entity describes the instance, but is not the instance. (I'm trying to avoid being overly pedantic, but talking about
