Objective-C: How do I save results to a second view controller?

Question

I am a noob and need some guidance. I haven't messed with programming in 7 years. In objective-C. How can I save results to a second view controller? Lets say root view controller is a calculator. After I get the result I want to be able to hit a save button and the data will be saved to the second view controller. The second view controller will list the results. I will want to be able to delete them with a swipe of my finger.

can you show me your code how you are transiting betweening view controller — Sunil Pandey, Jan 18 '13 at 00:53
Currently I don't have any code. I am basically finding examples and then building off of those. — user1988925, Jan 18 '13 at 01:48

Create a property data in the 2nd View controller, and before pushing / displaying the view controller you set that property.

Do bellow steps :

First you import your second view controller header file to first one. firstViewController.h

#import <UIKit/UIKit.h>
#import "secondViewController.h"

In second view controller header create a property secondViewController.h

@property NSString *passingValue;

Create a instance of secondViewController

secondViewController *targetVC ;
targetVC.passingValue = newValue;

Now you `@synthesize passingValue, in secondViewController.m

Now you can get values to secondViewController

- (void)viewDidLoad
{
    NSLog(@"Image Name : %@ ",passingValue);
   [super viewDidLoad];
}

the use of `@synthesize` is not needed anymore. it will be done as default with an underscore prefixed ivar. – vikingosegundo Jan 18 '13 at 03:19
