I have retrieves all contact by using following method
- (void)getAllContacts:(void(^)(NSArray *array))handler
{
CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
if (status == CNAuthorizationStatusDenied || status == CNAuthorizationStatusDenied)
{
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;
}
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
// make sure the user granted us access
if (!granted)
{
dispatch_async(dispatch_get_main_queue(), ^{
// user didn't grant access;
// so, again, tell user here why app needs permissions in order to do it's job;
// this is dispatched to the main queue because this request could be running on background thread
});
return;
}
// build array of contacts
NSMutableArray *contacts = [NSMutableArray array];
NSError *fetchError;
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:@[CNContactIdentifierKey, CNContactEmailAddressesKey, CNContactBirthdayKey, CNContactImageDataKey, CNContactPhoneNumbersKey, [CNContactFormatter descriptorForRequiredKeysForStyle:CNContactFormatterStyleFullName]]];
BOOL success = [store enumerateContactsWithFetchRequest:request error:&fetchError usingBlock:^(CNContact *contact, BOOL *stop) {
[contacts addObject:contact];
}];
if (!success)
{
NSLog(@"error = %@", fetchError);
return;
}
handler((NSArray *)contacts);
}];
}
And contacts are listed in tableview. Now I am trying to select particular contact from ``,
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
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];
}
But it says
Contact 0x7fc732654530 is missing some of the required key descriptors
Please help me to solve it, if anyone know. Thanks.
Add "CNContactViewController.descriptorForRequiredKeys" at the end of your keysToFetch array.
Worked for me after I did that.
Example:
NSArray *keysToFetch = @[CNContactIdentifierKey, CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey, CNContactImageDataAvailableKey, CNContactImageDataKey, CNContactViewController.descriptorForRequiredKeys];
