}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
DisplayImage *obj_display1=[[DisplayImage alloc]initWithNibName:#"DisplayImage" bundle:nil];
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
//self.imageview.image = chosenImage;
imageview.image=chosenImage;
obj_display1.imageDisplayy=chosenImage;**

.h file
#property(nonatomic,strong) UIImageView *imageDisplayy;
.m file
#synthesize imageDisplayy;
- (void)viewDidLoad {
[super viewDidLoad];
obj_imageview.image=imageDisplayy;
}

Answer 1

You are creating an instance of DisplayImage in your this method
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
While performing navigation you are creating another new instance which doesn't have imageDisplayy property set for it.
-(IBAction)display:(id)sender
{
DisplayImage *obj_display=[[DisplayImage alloc]initWithNibName:#"DisplayImage" bundle:nil];
[self.navigationController pushViewController:obj_display animated:YES];
}
One solution for this problem is make DisplayImage *obj_display1 as property in your ImagePicker.
#property(nonatomic,strong) DisplayImage *obj_display1;
Instantiate it in viewDidLoad
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.obj_display1=[[DisplayImage alloc]initWithNibName:#"DisplayImage" bundle:nil];
}
update code in this method as
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
//self.imageview.image = chosenImage;
imageview.image=chosenImage;
self.obj_display1.imageDisplayy=chosenImage;**
[picker dismissViewControllerAnimated:YES completion:NULL];
}
Then perform navigation
-(IBAction)display:(id)sender
{
[self.navigationController pushViewController:self.obj_display1 animated:YES];
}

Your are directly passing image to imagview.Instead of that pass image from one view controller to anorther.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
DisplayImage *obj_display1=[[DisplayImage alloc]initWithNibName:#"DisplayImage" bundle:nil];
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
//self.imageview.image = chosenImage;
imageview.image=chosenImage;
obj_display1.imageDisplayy=chosenImage;**
[picker dismissViewControllerAnimated:YES completion:NULL];
}
next page where want to display image
.h file
#property(nonatomic,strong) UIImage *imageDisplayy;
.m file
#synthesize imageDisplayy;
- (void)viewDidLoad {
[super viewDidLoad];
obj_imageview.image=imageDisplayy;
}

Answer 3

try this :
//In .h file
// change your property to UIImage instead of imageview
#property(nonatomic,strong) UIImage *imageDisplayy;
