Core Data is pretty amazing, and I've really enjoyed using the visual layout Xcode provides for it to organize things and get a quick sample of what data I've placed where. At times I've started to wonder if I'm making the best use of it, however, as after a while there tends to be such a mass of arrows that it becomes difficult to tell...
In the Nav Services world one could specify kNavDontConfirmReplacement as an option to create a NavDialogRef that would not ask the user to confirm the replacement of a file when saving with a file name that already exists. How do I specify an equivalent behavior with the Cocoa NSSavePanel? ...

I am sure they use something really fancy to create their documentations and guides. Everything is so streamlined and equal, and they always have a HTML and a PDF version.

When I hit the "+" button on a row in NSRuleEditor, a new row is created. How can I take influence on the criteria used for that row.

I've noticed that some of Apple's examples include both a retain and readonly modifier on properties. What's the point of including retain if no setter gets generated when we're using the readonly modifier? Example: @property (retain, readonly) NSString *title; from the AnimatedTableView sample. ...
Hey there, I'm fairly new at this, but I think what I'm looking to do makes sense. I have a xib that is displayed in portrait and one that is displayed in landscape. Both views are similar, but have a few differences. Some of the buttons, labels and textfields are the same. I can reveal one and hide the other when the orientation is...
Hi, I'm trying to build a color picker view on the iPhone. I want to draw one of those 'color maps' and let the user tap on the color. I can create a gradient (in the X axis) ok which gives me the color range, but I also want to combine the lightness (in the Y axis) which is where I'm struggling. Any help would be most welcome. Thanks...
