Holzner Quick Start Objective-C

[OnScreen]

I've used the SDK to start learning iPhone programming. Going back a step, as recommended, to learn some Objective-C. Using book by Steven Holzner, Visual Quickstart Guide, Objective-C. Followed directions to create my first program on my iMac. Compiles and runs, directions say "you should see this message"... where? The example is just using a simple printf command. Using Project - Command Line Tool - Foundation...


#import <Foundation/Foundation.h>

int main (void) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

// insert code here...
printf("Welcome to Objective-C.");


NSLog(@"Hello, World!");
[pool drain];
return 0;
}


also tried...


#import <stdio.h>

int main (void)
{
printf("Welcome to Objective-C!");

return 0;
}


I don't see any other reference to <stdio.h>

Now I am honestly a total noob, so I'm sorry if I get this wrong. But I'm pretty sure the printf() function is for C, not Objective-C. If you want to display that line just use another NSLog string.

Actually printf() will also work on objective-c program. Objective-c is a layer on top of C language, so you can use c language freely in your program.
You should be able to see the output on the console.
view->debug area->activate console will make it appear.
