Developing native applications
Objective-C & Cocoa for MacOSX

17. Objective-C & Cocoa
• Objective-C, a small superset of ANSI-C that allows object oriented programming
[object performActionWithParameter: aParameter];
• Cocoa, a powerful API for creating native MacOSX applications
Objective-C
Aqua UI
Runtime
Foundation Appkit Cocoa
ANSI-C
CoreFoundation

20. An example: dynamic plugins
• Importers / Exporters
• Search Engines
- (BOOL)readyToPerformSearch
• Protocols & Delegation
- (void) performSearchWithQuery:
• Simple but powerful - (void)didBeginSearch:(id)sender
- (void)didRetrieveObjects:(NSDictionary *)dict
• Dynamically loaded at runtime
- (void)didEndSearch: (id)sender;
- (BOOL)successfulCompletion;!
- (void) performCleanup;
