I used Below code to Fetch contact details from Device
CFErrorRef * error = NULL;
addressBook = ABAddressBookCreateWithOptions(NULL, error);
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error)
{
if (granted)
{
dispatch_async(dispatch_get_main_queue(), ^{
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));
NSString *name=[NSString stringWithFormat:#"%# %#",firstName,lastName];
NSString *Birthday=(__bridge NSString *)(ABRecordCopyValue(person, kABPersonBirthdayProperty));
NSLog(#"Name:%# %# %#", firstName, lastName,Birthday);
//For Email ids
NSMutableArray *Emails = [NSMutableArray array];
ABMutableMultiValueRef eMail = (__bridge ABMutableMultiValueRef)((__bridge NSString *) ABRecordCopyValue(person, kABPersonEmailProperty));
for (CFIndex i = 0; i < ABMultiValueGetCount(eMail); i++) {
NSString *emails = (__bridge_transfer NSString *) ABMultiValueCopyValueAtIndex(eMail, i);
[Emails addObject:emails];
}
ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);
NSMutableArray *numbers = [NSMutableArray array];
for (CFIndex i = 0; i < ABMultiValueGetCount(phoneNumbers); i++) {
NSString *phoneNumber = (__bridge_transfer NSString *) ABMultiValueCopyValueAtIndex(phoneNumbers, i);
[numbers addObject:phoneNumber];
}
NSMutableDictionary *contact = [NSMutableDictionary dictionary];
[contact setObject:firstName forKey:#"First"];
[contact setObject:lastName forKey:#"Last"];
[contact setObject:numbers forKey:#"numbers"];
[contact setObject:Emails forKey:#"Email"];
NSLog(#" contacts are %#",contact);
[all_contacts addObject:contact];
NSLog(#"all contacts are %#",all_contacts);
[self.tbl_contacts reloadData];
}
});
}
});

First pick the required contact:
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker
shouldContinueAfterSelectingPerson:(ABRecordRef)person
{
[self peoplePickerNavigationController:peoplePicker didSelectPerson:person];
return NO;
}
Refer this: for setting and getting first name and last name
ABRecordRef aRecord = ABPersonCreate();
CFErrorRef anError = NULL;
bool didSet;
didSet = ABRecordSetValue(aRecord, kABPersonFirstNameProperty, CFSTR("Katie"), &anError);
if (!didSet) {/* Handle error here. */}
didSet = ABRecordSetValue(aRecord, kABPersonLastNameProperty, CFSTR("Bell"), &anError);
if (!didSet) {/* Handle error here. */}
CFStringRef firstName, lastName;
firstName = ABRecordCopyValue(aRecord, kABPersonFirstNameProperty);
lastName = ABRecordCopyValue(aRecord, kABPersonLastNameProperty);
/* ... Do something with firstName and lastName. ... */
CFRelease(aRecord);
CFRelease(firstName);
CFRelease(lastName);
