You are saving the image in the Detail Controller before you make the push?

DetailController *detailVC=[[DetailController alloc]
                          initWithNibName:@"DetailController"
                          bundle:nil];

detailVC.image = self.image;

[self.navigationController pushViewController:detailVC animated:YES];

but the same code i have tried it is not displaying the editted image in the share view controller i.e, in third view controller – Aruna M Mar 21 '14 at 09:30
Try to pass the info as well with Delegaton, Notifications or Key Value Coding – santibernaldo Mar 21 '14 at 09:34
one more thing that i like to say is the second view controller i am doing deep copy of image as an edited image so can u please go through the code – Aruna M Mar 21 '14 at 10:13
- (id)initWithImage:(UIImage *)image { self = [self init]; if (self){ originalImage = [image deepCopy]; NSLog(@"original image is %@",originalImage); } return self; } – Aruna M Mar 21 '14 at 10:13
the above original image is having the edited image and i need to send it to share view controller after clicking on share button i should share the image – Aruna M Mar 21 '14 at 10:15
for displaying the image in another view controller i am using this below code [_pickedImageView setImage:_clView.originalImage]; – Aruna M Mar 21 '14 at 10:18

Delegation

You implement the protocol on your View Controller

In Controller.h:

@class Controller;

@protocol ControllerDelegate <NSObject>

- (void)sendFrom:(Controller *)controller
                   image:(UIImage *)image;

@end

@interface Controller : UIViewController

@property (weak, nonatomic) NSObject <ControllerDelegate> * delegate;

@end

In Controller.m when you want send the image:

[self.delegate sendFrom:self
         image: self.image];

After on your Detail View Controller, don't forget to assign it as delegate of the Controller. And to implement the ControllerDelegate protocol. To do that:

In your DetailController.h implement the protocol. You can do that on your .m as well.

#import "Controller.h"

@interface DetailController : UIViewController <ControllerDelegate>

You keep a reference of the Controller in The Detail Controller

@property (nonatomic, strong) ViewController *controller;

And assign its delegate in the viewDidLoad of the Detail Controller. For example:

-(void)viewDidLoad:(BOOL)animated{

      [super viewDidLoad:animated];

      self.controller.delegate = self;
   }

Don't forget to implement the protocol method in your Detail View. Here you receive the image you passed from Controller and you save it in your Detail Controller UIImage property:

- (void)sendFrom:(Controller *)controller
                       image:(UIImage *)image{

   self.image = image;
}

You can implement storyboard segue to your detail controller and use following sample code.

- (void)cropButtonClick:(id)sender
{
    [self performSegueWithIdentifier: @"MySegue" sender:sender];
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"MySegue"]) {
        DetailController *detailVC = segue.destinationViewController;
        [detailVC setImage:self.image];
    }
}
