Program 3.3 Output Issue

[Kale2312]

I am having some trouble with the Output area of Xcode. I'm pretty sure I have the code exactly matching what is in the book however when I Run the program it produces the following:

2012-07-24 11:06:28.332 Program 3.3[990:403]
First fraction is:
2012-07-24 11:06:28.334 Program 3.3[990:403]
2/3

It does't show anything about frac2. Am I doing something wrong? Everything I have typed is below.

//  Program 3.3

#import <Foundation/Foundation.h>

//----@interface section----

@interface Fraction: NSObject

-(void) print;
-(void) setNumerator: (int) n;
-(void) setDenominator: (int) d;

@end

//  ----@implementation section----

@implementation Fraction

{
    int numerator;
    int denominator;
}
-(void) print
{
    NSLog (@"\n%i/%i", numerator, denominator);
}
-(void) setNumerator: (int) n
{
    numerator = n;
}
-(void) setDenominator: (int) d
{
    denominator = d;
}

@end

//  ----program section----

int main (int argc, char * argv[])

{
    @autoreleasepool {
        Fraction *frac1 = [[Fraction alloc] init];
        Fraction *frac2 = [[Fraction alloc] init];
       
        //  Set 1st fraction to 2/3
       
        [frac1 setNumerator: 2];
        [frac1 setDenominator: 3];
       
        //  Set 2nd fraction to 3/7
       
        [frac2 setNumerator: 3];
        [frac2 setDenominator: 7];
       
        //  Display the fractions
       
        NSLog (@"\nFirst fraction is:");
        [frac1 print];
       
        NSLog (@"\nSecond fraction is:");
        [frac2 print];
    }
    return 0;
}
