Getting "global" mouse position in Mac OS X

How can I get in Mac OS X "global" mouse position - I mean how can I in cocoa/cf/whatever find out cursor position even if it's outside the window, and even if my window is inactive?

What should I do with default menu items in MainMenu in the new Cocoa application?

When you create new Cocoa application Xcode generates MainMenu.xib for you with the sets of predefined menu items (File, Edit, Format, View, etc.). I make a very simple application.

Encoding Large Object Graph Using NSKeyedArchiver Eats Memory

I'm using a NSKeyedArchiver to encode a big object graph (76295 objects.) It takes a lot of time but even worse the NSKeyedArchiver doesn't give back all its memory. After using the Leak check, the code doesn't appear to leak at all but for some reason the encoding doesn't give back all memory after it's done. Calling the encode method...

Testing controller method with OCMock and Core Data

I am just grasping the concepts of TDD and mocking, and am running into an issue in terms of how to properly. I have a sheet that drops down and lets a user create a new core data object and save it to the data store.

Better alternative for checking existence of NSDictionary's key in NSArray?

Better alternative for "data-only" Objective-C objects?

I run into design choices like this often and struggle a bit; I'm looking for some other perspectives. I often want to keep lists of, or pass around chunks of state that are basically just sets of values. The values tend to be primitive types: floats, NSTimeIntervals, CGPoints, etc. My first inclination is often to create C structures ...

Any alternatives to NSDictionary for unique keys AND unique values?

I'm in the middle of writing some Cocoa classes to parse ID3 tags from MP3 files. To make them as easy to use as possible, I'm allowing the option to request a tag by the actual ID3 frame id ("TCON", "TPE1", "TALB", etc.) or an equivalent word/phrase ("genre", "artist", "album", etc.) To store this data, currently I have a reference cla...

Cocoa: How to morph a drag image while dragging
