temp converter part two

8. After ViewController.h done then click on ViewController.m, you could find the code at ViewController.m like the code below:

//

//  ViewController.m

//  converter

//

//  Created by.... on....

//  Copyright (c) 2012 your company. All rights reserved.

//

#import "ViewController.h"

@implementation ViewController

@synthesize fahrenheit;

@synthesize celsius;

*Note = these codes below came from IBOutlet on ViewController.h that we made it before.

@synthesize fahrenheit;

@synthesize celsius;

next step is =

insert the following code just below the code

-(void)viewDidLoad

{

    [super viewDidLoad]; 

the code is =

fahrenheit.keyboardType = UIKeyboardTypeDecimalPad;

9.  Change the code below =

- (IBAction)convert:(id)sender {

}

copy and paste with the code below =

 - (IBAction)convert:(id)sender {

    float x = [[fahrenheit text] floatValue];

    float y = (x - 32.0f) * 5.0f / 9.0f;

    [celsius setText : [NSString stringWithFormat:@"%.3.2f", y]];

    [fahrenheit resignFirstResponder];

}

then run the application, have a nice try
