Hello, I'm in the midst of porting a win32 app to cocoa. Wherever possible, I'm using IB, since... well its way easier in every way possible, obviously. One thing is the designer and the win32 dev set up all the button assets on a massive "sprite sheet" such you move around the viewport to determine button state. Similar to how yahoo do...

I've seen there is a library called InAppSettingsKit - http://www.inappsettingskit.com/ - which lets your in-app settings mimic your settings within the Settings app. But is there a way to get this to NOT use the Settings app as well?

But when I move it to a separate "BSJax" class and call it with the same input parameter it throws an unrecognized selector error. Here's the call: BSjax *bsjax = [BSjax new]; NSString *hexString = ...
I understand CGFloat should be used in Cocoa applications to make them 64-bit clean. But what about in a simple OpenGL game that uses Cocoa/Objective-C for everything but the rendering (to an NSOpenGLView)? CGFloat is a part of Core Graphics, so if I would it also be alright to use CGPoint, CGRect etc.? or should I just write rects and v...
