A basic Cocoa application for beginners to Cocoa and Objective-C. This application displays different "Hello Cocoa" dialogs to the user based upon radio-button and PopUp menu selections. The user can change which hello message is sent by selecting a different radio button. The user can change which Hello object receives the message by changing the PopUp menu selection. The dynamic nature of the Objective-C runtime and the power of Cocoa help make this "on-the-fly" code-path execution possible and the GUI easy to program.


This sample requires OS X 10.4 or higher.
