Adding contact into ios addressbook - iphone

Question

I want to add contacts into my address book. I am developing an app where I have gone through many links, and I have following code, but now I am stuck.
I have imported:
#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h
in viewcontroller.m:
-(IBAction)addToAddressbook:(id)sender{
ABUnknownPersonViewController *unknownPersonViewController = [[ABUnknownPersonViewController alloc] init];
unknownPersonViewController.displayedPerson = (ABRecordRef)[self buildContactDetails];
unknownPersonViewController.allowsAddingToAddressBook = YES;
[self.navigationController pushViewController:unknownPersonViewController animated:YES];
[unknownPersonViewController release];
}
- (ABRecordRef)buildContactDetails {
NSLog(#"building contact details");
ABRecordRef person = ABPersonCreate();
CFErrorRef error = NULL;
// firstname
ABRecordSetValue(person, kABPersonFirstNameProperty, #"Don Juan", NULL);
// email
ABMutableMultiValueRef email = ABMultiValueCreateMutable(kABMultiStringPropertyType);
ABMultiValueAddValueAndLabel(email, #"expert.in#computer.com", CFSTR("email"), NULL);
ABRecordSetValue(person, kABPersonEmailProperty, email, &error);
CFRelease(email);
// Start of Address
ABMutableMultiValueRef address = ABMultiValueCreateMutable(kABMultiDictionaryPropertyType);
NSMutableDictionary *addressDict = [[NSMutableDictionary alloc] init];
[addressDict setObject:#"The awesome road numba 1" forKey:(NSString *)kABPersonAddressStreetKey];
[addressDict setObject:#"0568" forKey:(NSString *)kABPersonAddressZIPKey];
[addressDict setObject:#"Oslo" forKey:(NSString *)kABPersonAddressCityKey];
ABMultiValueAddValueAndLabel(address, addressDict, kABWorkLabel, NULL);
ABRecordSetValue(person, kABPersonAddressProperty, address, &error);
[addressDict release];
CFRelease(address);
// End of Address
if (error != NULL)
NSLog(#"Error: %#", error);
[(id)person autorelease];
return person;
}
In UI I have an IBAction button connected to addToAddressbook, but on click, nothing is happening - so what else to do I need to do in UI or in the code?

Answer 1

After looking at your code i can see that you are missing the ABAddressBookSave statement. After setting the values of
// firstname
ABRecordSetValue(person, kABPersonFirstNameProperty, #"Don Juan", NULL);
// email
ABRecordSetValue(person, kABPersonEmailProperty, email, &error);
// Address
ABRecordSetValue(person, kABPersonAddressProperty, address, &error);
You should call ABAddressBookSave which is as follows.
ABAddressBookSave(ABAddressBookRef addressBook, CFErrorRef* error);
