Well for this kind of method, you would have to create a singleton class like ShareClass.h or if you are really new (and dont know about this) , in the AppDelegate.h wherein you would have to declare a UIImage say UIImage *SavedImage .

Now call this class in the view where you are capturing the image . Then save this captured image in the SavedImage . To share this image you would then call the ShareClass.h class or the AppDelegate.h in the view in which you want to share the image and display it in the UIImageView .

Any clarifications please ask. :)

In the ShareClass.h

UIImage *SavedImage;
@interface ShareClass : NSObject
{

}

In the Class where the image was captured, First import the ShareClass.h , then

        imagepicker.sourceType = UIImagePickerControllerSourceTypeCamera;
        if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
        {
            imagepicker.sourceType = UIImagePickerControllerSourceTypeCamera;
            SavedImage = UIImagePickerControllerSourceTypeCamera;
            [self presentViewController:imagepicker animated:YES completion:NULL];                
        }

In the Class where the image should be displayed again import the ShareClass.h

UIImageView *DisplayImage = [[UIImageView alloc]initWithImage:[UIImage imageNamed:SavedImage]];
DisplayImage.frame=CGRectMake(0, 0, 20, 20);
[self.view addSubView:DisplayImage];
