Answer 1

Following code for retrieving contact details.
- (void)viewDidLoad {
[super viewDidLoad];
contactList=[[NSMutableArray alloc] init];
ABAddressBookRef m_addressbook = ABAddressBookCreate();
if (!m_addressbook) {
NSLog(#"opening address book");
}
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(m_addressbook);
CFIndex nPeople = ABAddressBookGetPersonCount(m_addressbook);
for (int i=0;i < nPeople;i++) {
NSMutableDictionary *dOfPerson=[NSMutableDictionary dictionary];
ABRecordRef ref = CFArrayGetValueAtIndex(allPeople,i);
//For username and surname
ABMultiValueRef phones =(NSString*)ABRecordCopyValue(ref, kABPersonPhoneProperty);
CFStringRef firstName, lastName;
firstName = ABRecordCopyValue(ref, kABPersonFirstNameProperty);
lastName = ABRecordCopyValue(ref, kABPersonLastNameProperty);
[dOfPerson setObject:[NSString stringWithFormat:#"%# %#", firstName, lastName] forKey:#"name"];
//For Email ids
ABMutableMultiValueRef eMail = ABRecordCopyValue(ref, kABPersonEmailProperty);
if(ABMultiValueGetCount(eMail) > 0) {
[dOfPerson setObject:(NSString *)ABMultiValueCopyValueAtIndex(eMail, 0) forKey:#"email"];
}
//For Phone number
NSString* mobileLabel;
for(CFIndex i = 0; i < ABMultiValueGetCount(phones); i++) {
mobileLabel = (NSString*)ABMultiValueCopyLabelAtIndex(phones, i);
if([mobileLabel isEqualToString:(NSString *)kABPersonPhoneMobileLabel])
{
[dOfPerson setObject:(NSString*)ABMultiValueCopyValueAtIndex(phones, i) forKey:#"Phone"];
}
else if ([mobileLabel isEqualToString:(NSString*)kABPersonPhoneIPhoneLabel])
{
[dOfPerson setObject:(NSString*)ABMultiValueCopyValueAtIndex(phones, i) forKey:#"Phone"];
break ;
}
[contactList addObject:dOfPerson];
CFRelease(ref);
CFRelease(firstName);
CFRelease(lastName);
}
NSLog(#"array is %#",contactList);
}
}

Add Framwork
#import <AddressBook/AddressBook.h>
#import <AddressBook/ABPerson.h>
#import <AddressBookUI/AddressBookUI.h>
use delegate
<ABPeoplePickerNavigationControllerDelegate,ABPersonViewControllerDelegate,ABNewPersonViewControllerDelegate,ABUnknownPersonViewControllerDelegate>
You can show your contact by ABPeoplePickerNavigationController
ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
[[picker navigationBar] setBarStyle:UIBarStyleBlack];
picker.peoplePickerDelegate = self;
// Display only a person's phone, email, and birthdate
NSArray *displayedItems = [NSArray arrayWithObjects:[NSNumber numberWithInt:kABPersonPhoneProperty],nil];
picker.displayedProperties = displayedItems;
// Show the picker
[self presentModalViewController:picker animated:YES];
[picker release];
and after you initialize then you need to use following method
#pragma mark - ABPeopelPickerNavigationController Delegate and DataSource Methods
- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker
{
[self dismissModalViewControllerAnimated:YES];
}
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
{
// For get People detail
}
- (void)unknownPersonViewController:(ABUnknownPersonViewController *)unknownCardViewController didResolveToPerson:(ABRecordRef)person
{
}
- (void)newPersonViewController:(ABNewPersonViewController *)newPersonView didCompleteWithNewPerson:(ABRecordRef)person
{
}
- (BOOL)personViewController:(ABPersonViewController *)personViewController shouldPerformDefaultActionForPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
{
return YES;
}
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier;
{
return YES;
}

use
ABRecordID recordId;
ABAddressBookRef _addressBookRef = ABAddressBookCreate ();
NSArray* allPeople = (NSArray *)ABAddressBookCopyArrayOfAllPeople(_addressBookRef);
NSString* compositeName = (NSString *)ABRecordCopyCompositeName((ABRecordRef)record);
recordId = ABRecordGetRecordID(record);
ABMultiValueRef emails = ABRecordCopyValue(record, kABPersonEmailProperty);
