How to open Edit Contacts Screen for Specific Contact - ios

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 2

Answer 1

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];
}
#pragma mark - Methods

- (void)getContactsUsingAddressbook
{
ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();
if (status == kABAuthorizationStatusDenied || status == kABAuthorizationStatusRestricted)
{
UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil message:#"This app previously was refused permissions to contacts; Please go to settings and grant permission to this app so it can use contacts" preferredStyle:UIAlertControllerStyleAlert];
[alert addAction:[UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:nil]];
[self presentViewController:alert animated:TRUE completion:nil];
return;
}
CFErrorRef error = NULL;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, &error);
if (!addressBook)
{
NSLog(#"ABAddressBookCreateWithOptions error: %#", CFBridgingRelease(error));
return;
}
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
if (error)
{
NSLog(#"ABAddressBookRequestAccessWithCompletion error: %#", CFBridgingRelease(error));
}
if (granted)
{
NSArray *allPeople = CFBridgingRelease(ABAddressBookCopyArrayOfAllPeople(addressBook));
arrContacts = [NSMutableArray arrayWithArray:allPeople];
[tblContacts reloadData];
}
else
{
dispatch_async(dispatch_get_main_queue(), ^{
[[[UIAlertView alloc] initWithTitle:nil message:#"This app requires access to your contacts to function properly. Please visit to the \"Privacy\" section in the iPhone Settings app." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil] show];
});
}
CFRelease(addressBook);
});
}
#pragma mark - Tableview delegate

}

ABRecordRef person = (__bridge ABRecordRef)arrContacts[indexPath.row];
NSString *firstName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonFirstNameProperty));

cell.textLabel.text = [NSString stringWithFormat:#"%# %#", firstName, lastName];
return cell;
}

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];
}
#pragma mark - ABPersonview delegate
- (BOOL)personViewController:(ABPersonViewController *)personViewController shouldPerformDefaultActionForPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
{
return TRUE;
}
And see in my simulator

Answer 2

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

Answer 3

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];
