How to open Edit Contacts Screen for Specific Contact

Question

I am working on a iOS Application in which I have to add contacts in Address Book.

I want to open Edit Contact Screen Whenever user Tries to add duplicate contact.

But I don't know how to do that.Currently I am only able to show a message only.

I am getting all contacts list as:

 NSArray *allContacts = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBookRef);

Then I am itterating through it and check for existing one.If it exists then I am showing a message else I will add it to the addressbook.

     for (id record in allContacts){
    ABRecordRef thisContact = (__bridge ABRecordRef)record;
    if (CFStringCompare(ABRecordCopyCompositeName(thisContact),
                        ABRecordCopyCompositeName(pet), 0) == kCFCompareEqualTo){
        //The contact already exists!
        NSLog(@"contact exosts");
    }
    else
    {
        ABAddressBookAddRecord(addressBookRef, pet, nil);
        ABAddressBookSave(addressBookRef, nil);
          ABMultiValueAddValueAndLabel(phoneNumbers, (__bridge CFStringRef)petPhoneNumber, kABPersonPhoneMainLabel, NULL);
        NSLog(@"contacts Added");
    }
}

How can I open following screen when user Tries to add duplicate contact:

I searched SO and find following questions but this doesn't help me. Question 1 Question 2

And Is it possible to do so or not.Please any one assist me to achieve this feature if it is feasible.

See here .h

#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>

@interface ContactsViewController : UIViewController <UITableViewDataSource, UITableViewDelegate, ABPersonViewControllerDelegate>
{
    IBOutlet UITableView *tblContacts;
    NSMutableArray *arrContacts;
}
@end

And .m

#import "ContactsViewController.h"

@interface ContactsViewController ()
{
    UIAlertController *action;
}
@end

@implementation ContactsViewController

#pragma mark - View lifecycle

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.title = @"Contacts";
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addNewContact:)];
    [self getContactsUsingAddressbook];
}

You can edit contact as following

Here you have to add

// ------- Deprecated (in iOS 9.0)

#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>

ABPersonViewController *personController = [[ABPersonViewController alloc] init];
personController.personViewDelegate = self;
personController.displayedPerson = (__bridge ABRecordRef)arrContacts[indexPath.row];
personController.allowsEditing = YES;
personController.allowsActions = YES;
[self.navigationController pushViewController:personController animated:TRUE];

And here

#import <Contacts/Contacts.h>
#import <ContactsUI/ContactsUI.h>

// -------- This is not working for me, I got error
CNContact *contact = [arrContacts objectAtIndex:indexPath.row];
NSArray *keys = @[CNContactIdentifierKey, CNContactEmailAddressesKey, CNContactBirthdayKey, CNContactImageDataKey, CNContactPhoneNumbersKey, [CNContactFormatter descriptorForRequiredKeysForStyle:CNContactFormatterStyleFullName]];
CNContactViewController *contactController = [CNContactViewController viewControllerForContact:contact];
contactController.delegate = self;
contactController.allowsEditing = YES;
contactController.allowsActions = YES;
contactController.displayedPropertyKeys = keys;
[self.navigationController pushViewController:contactController animated:TRUE];

See here Contact is missing some of the required key descriptors in ios

But still I have not found solution , If you have please tell me

let me try this one...arrContacts[indexPath.row] is it the index of contact to be edited ? — Rahul, Nov 20 '15 at 05:24
Any one of them, depending up on your iOS version. If you are targeting both iOS 8.0 and iOS 9.0 then implement both in conditional way — VRAwesome, Nov 20 '15 at 05:31

Here is the answer when bind arrayOfContact That time have to Provide key with [CNContactViewController descriptorForRequiredKeys].

NSArray *keys = @[CNContactGivenNameKey,CNContactFamilyNameKey,CNContactOrganizationNameKey, CNContactPhoneNumbersKey, CNContactEmailAddressesKey,CNContactPostalAddressesKey,[CNContactViewController descriptorForRequiredKeys]]
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:keys];

when open existing Contact

  CNContactViewController *contactController = [CNContactViewController viewControllerForContact:contact];

  contactController.delegate               =   self;
  contactController.allowsEditing          =   YES;
  contactController.allowsActions          =   YES;
  [self.navigationController pushViewController:contactController animated:TRUE];
