Testing Music Library in the iPhone emulator
I'd like to be able to debug my application in the iPhone emulator.

drawing in other processes windows on macosx?
Is it possible to draw in other processes windows on MacOSX using Cocoa or other libraries? If yes, are there any samples? Alternatively a quick summary of what i'd have to do?

Landscape mode and locationInView in opengl es
So today I implement landscape mode for my app. It is an opengl es application. I rotated it 90 degrees. The first thing I notice is that the touches no longer work.

Reposition an NSBox in the top pane of a horizontal NSSplitView
I've worked for hours on this and I just can't get it - should be really basic stuff but it's not getting thru my thick skull. I think it has to do with the coordinate system in Cocoa but I really don't know. This is all happening in the top pane of a horizontal NSSplitView. Very simply, I'm trying to position one NSBox right below a ...

How to set up gcov for code coverage analysis in iPhone SDK?
Hi, I've recently begun unit testing an app I write for the iPhone. I have the basics of creating my own tests down, even if it seems a little sub-optimal.

Any help would be very appreciated! —Alb...

Magic Mouse Momentum Scrolling Not Working
Unfortunately this is hard for me to test myself because I have yet to get a Magic Mouse of my own, but I've been told by my testers who do have a magic mouse that momentum scrolling isn't working in my app. I've not subclassed NSScrollView, but scrollview's document view is all custom. I have not overridden scrollWheel: anywhere, either...
