Xcode, Interface Builder und Co. are very powerful tools, but sometimes they seem to make things a little bit more complicated than they really are. Here's a short program in Objective-C: | |||
<source lang="objc"> | |||
#import <Foundation/Foundation.h> | |||
int main (int argc, const char * argv[]) { | |||
@autoreleasepool { | |||
// Hello World! | |||
printf("About to print the most important message...\n"); | |||
NSLog(@"Hello World!\n"); | |||
} | |||
return 0; | |||
} | |||
</source> | |||
You can compile either with a simple Editor that supports this (e.g. [http://macromates.com/ TextMate]: Actions: Run) - or you use the gcc compiler with Bash (Terminal.app): | |||
<source lang="bash"> | |||
cd ~/Path/to/HelloWorld.m | |||
clang HelloWorld.m -o HelloWorld -framework Foundation | |||
./HelloWorld | |||
</source> | |||
