			== NeXTStep ==
			Cocoa and Objective-C kind of belong to each other. Usually you'll hear that Objective-C is only useful on Mac OS and bound to Apple Stuff only, but this is not true: While NeXTStep originated over 20 years ago, there's also GNUstep which aims to bring Cocoa to all major OS (*nix & Windows):
			* [http://www.gnustep.org/ GNUstep.org]
			** [http://en.wikipedia.org/wiki/GNUstep GNUstep on Wikipedia]
			** [http://en.wikipedia.org/wiki/NeXTStep History of NeXtStep]

			Basically GNUstep's Project Center is like Xcode and Gorm is like Interface Builder.

			...btw, that's where all the NS-Prefixes come from ('''N'''eXT'''S'''tep), eg in NSObject, NSArray, ...

== Hello World ==

Xcode, Interface Builder und Co. können sehr viel, aber für den Anfang lassen sie vieles komplizierter erscheinen als es ist. Hier ist ein kurzes Programm in Objective-C.

<source lang="objc">
#import <Foundation/Foundation.h>

int main (int argc, const char * argv[]) {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

// Hello World!
NSLog(@"About to print the most important message...");
printf("Hello World!\n");

[pool release];
return 0;
}
</source>

Kompilieren kann man das z.B. mit TextMate (einfach unter Actions > Run wählen) oder im Terminal mit:
<source lang="bash">
cd ~/Path/to/HelloWorld.m
gcc HelloWorld.m -o HelloWorld -framework Foundation
./HelloWorld
</source>
