Hi. I'd like to make a sum with three text fields and a button.

I've defined a class called “fusebox” containing three outlets called numberField1, numberField2 and answerField, and a class action called calculateAnswer. I connected the object to the outlets and the action to the Fusebox object.

Then I saved the Fusebox class and imported it into project.

This is the code of fusebox.h

#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>

@interface Fusebox : NSObject {
    IBOutlet id answerField;
    IBOutlet id numberField1;
    IBOutlet id numberField2;
}
- (IBAction)calculateAnswer;
@end

this is Fusebox.m

#import “Fusebox.h”

@implementation Fusebox
- (IBAction)calculateAnswer {
   
    int num1,num2,answer;
   
    num1 = [numberField1 intValue];
    num2 = [numberField2 intValue];
    answer = num1 + num2;
   
    answerField.text = [NSString stringWithFormat:@"%d", answer];

   
   
}
@end

Here is my problem: I don't know how to associate the sum variable to the answerField.

In Cocoa it would be:

[answerField setIntValue:answer];

but what is the iPhone version?

Thanks in advance, please help me. I'm trying to learn but it's not so easy without a good book to learn from
