How to print Fibonacci series in Objective-C

#import <Foundation/Foundation.h>

int fibonacci(int n)
{
if(n<=2)
return(1);
return fibonacci(n-1) + fibonacci(n-2);
}

int main (int argc, const char * argv[])
{
   NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
   int i;
   for(i=1;i<=8;i++)
   {
   int fib=fibonacci(i);
   NSLog (@"%d,",fib);
   }
 [pool drain];
   return 0;
}
