    <p>I need some help getting correct results on fraction results. After adding them together and reducing, they should show a final result of 3/4, but I'm getting a result of 3/1. Can you show me where my functions are wrong?</p> <p>Fraction.h</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; //The fraction class @interface Fraction : NSObject { int numerator; int denominator; } @property int numerator, denominator; -(void) print; -(void) setTo:(int)n over:(int)d; -(double) convertToNum; -(void) add: (Fraction *) f; -(void) reduce; @end </code></pre> <p>Fraction.m </p> <pre><code>#import "Fraction.h" @implementation Fraction @synthesize numerator, denominator; -(void) print{ NSLog(@"%i/%i", numerator, denominator); } -(double) convertToNum{ if (denominator != 0) return (double) numerator/denominator; else return 1.0; } -(void) setTo:(int)n over:(int)d{ numerator = n; denominator = d; } //add a fraction to the receiver -(void) add: (Fraction *) f { //To add two fractions //a/b + c/d = ((a*d) + (b*c))/(b * d) numerator = (numerator * [f denominator]) + (denominator * [f numerator]); denominator = [f denominator]; [self reduce]; } -(void) reduce{ int u = numerator; int v = denominator; int temp; while (v!=0) { temp = u % v; u = v; v = temp; } numerator /= u; denominator /= u; } @end </code></pre> <p>FractionTest.m</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; #import "Fraction.h" int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; Fraction *aFraction = [[Fraction alloc]init]; Fraction *bFraction = [[Fraction alloc]init]; //Set two fractions to 1/4 and 1/2 and add them together [aFraction setTo:1 over:4]; [bFraction setTo:1 over:2]; //Print the results [aFraction print]; NSLog(@"+"); [bFraction print]; NSLog(@"="); [aFraction add:bFraction]; //reduce the result of the addition and print the result [aFraction reduce]; [aFraction print]; [aFraction release]; [bFraction release]; [pool drain]; return 0; } </code></pre> <p>Can you tell what I'm doing wrong?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
