Answer 1

To present default contact controller

Step 1: Add ContactUi.framework into project and import

    #import 
    #import 

Step2: Add this code

 -(void)showAddContactController{
        //Pass nil to show default contact adding screen
        CNContactViewController *addContactVC = [CNContactViewController viewControllerForNewContact:nil];
        addContactVC.delegate=self;
        UINavigationController *navController   = [[UINavigationController alloc] initWithRootViewController:addContactVC];
        [viewController presentViewController:navController animated:NO completion:nil];
    }

Step3:

For getting call back when pressing DONE or CANCEL, Add and implement the delegate method.

- (void)contactViewController:(CNContactViewController *)viewController didCompleteWithContact:(nullable CNContact *)contact{
    //You will get the callback here
}
