使用未声明的标识符“ NSButtonCell”

Question

I am trying to implement some radio button functionality. I found this page but when I try to use the classes NSButtonCell, NSRect and NSMatrix I get the error:

Use of undeclared identifier 'NSButtonCell'

Use of undeclared identifier 'NSRect'

Use of undeclared identifier 'NSMatrix'

I tried to import AppKit/AppKit.h but I get file not found. After reading this I changed it to UIKit/UIKit.h but the problem remains.

How can I solve this?

NSButton is only for mac applications, i think.

Create uibutton with background image. It will be easier and simple.
