Automatically add contacts from address book to tableview - ios

Question

I'm trying to get my contacts list in iOS to automatically add contacts to the contacts list without the user having to manually do it - similiar to how Whatsapp works. My code below simply shows prewritten values for the tableView and allows a bar button item to display the contacts list but not allow it to write any new entries to the tableView.
- (void)viewDidLoad
{
CFErrorRef *error = NULL;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, error);
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex numberOfPeople = ABAddressBookGetPersonCount(addressBook);
for(int i = 0; i < numberOfPeople; i++) {
ABRecordRef person = CFArrayGetValueAtIndex( allPeople, i );
NSString *firstName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonFirstNameProperty));
NSString *lastName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonLastNameProperty));
NSLog(#"Name:%# %#", firstName, lastName);
ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);
for (CFIndex i = 0; i < ABMultiValueGetCount(phoneNumbers); i++) {
NSString *phoneNumber = (__bridge_transfer NSString *) ABMultiValueCopyValueAtIndex(phoneNumbers, i);
NSLog(#"phone:%#", phoneNumber);
}
}
self.friendsSearch.delegate = self;
self.friendsTableView.delegate = self;
self.friendsTableView.dataSource = self;
friendsListArray = [[NSMutableArray alloc] initWithObjects:

-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
if(searchText.length == 0){
isFiltered = NO;
}
else
{
isFiltered = YES;
filterDataArray = [[NSMutableArray alloc]init];
for(NSString *str in friendsListArray){
NSRange stringRange = [str rangeOfString:searchText options:NSCaseInsensitiveSearch];
if (stringRange.location != NSNotFound){
[filterDataArray addObject:str];
}
}
}
[self.friendsTableView reloadData];
}
-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
[self.friendsSearch resignFirstResponder];
[self.view endEditing:YES];
}
// Table view datasource and delegate methods..

-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

}

return 1;
}
