Addressbook Reading in iOS

To get the basic fields, below few code can be used. 

ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, error);

Now get the permission if we have not already

 if (ABAddressBookRequestAccessWithCompletion != NULL) {

                dispatch_semaphore_t sema = dispatch_semaphore_create(0);

                ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {

                    dispatch_semaphore_signal(sema);

                });

                dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);

}

//Now get the array of all people. 

CFArrayRef allPeople =

            ABAddressBookCopyArrayOfAllPeople(addressBookRef);

            CFIndex nPeople = ABAddressBookGetPersonCount(addressBookRef);

if (allPeople != nil)

{

    for ( int i = 0; i < nPeople; i++ )

    {

         ABRecordRef ref = CFArrayGetValueAtIndex(allPeople, i);

         ABRecordID recordId = ABRecordGetRecordID(ref);

         CFStringRef lastNameMultiValueCF = ABRecordCopyValue(ref, kABPersonLastNameProperty);

         CFStringRef firstNmaeMultiValueCF = ABRecordCopyValue(ref, kABPersonFirstNameProperty);

         CFStringRef companyNameMultiValueC = ABRecordCopyValue(ref, kABPersonOrganizationProperty);

         CFStringRef nickNameMultiValueC = ABRecordCopyValue(ref, kABPersonNicknameProperty);

     }

}

Each of these CFStringRef can be converted to NSString using the type casting. Given below 

NSString *firstName =  (__bridge NSString *)firstNmaeMultiValueCF;

Getting all phone numbers:

ABMultiValueRef phoneNumsRef= ABRecordCopyValue(ref,kABPersonPhoneProperty);

if(phoneNumsRef)

{

NSArray *phNumbers = (__bridge_transfer NSArray*)ABMultiValueCopyArrayOfAllValues(phoneNumsRef);

if(phNumbers)

{

for(int j = 0; j < [phNumber count]; j++)

        {

//get the phone number

NSString *ph = [phNumber objectAtIndex:j];

//Now get the label for this address book item

NSString *label = nil;

CFStringRef unlocalizedLabel = ABMultiValueCopyLabelAtIndex(phoneNumbarsRef, j);

           if (unlocalizedLabel)

           {

               label = CFBridgingRelease(ABAddressBookCopyLocalizedLabel(unlocalizedLabel));

                                    CFRelease(unlocalizedLabel);

           }

    }

}

}

Getting all email values

Reading all emails is similar way as reading the phone number and the code is like below 

ABMultiValueRef emailRef= ABRecordCopyValue(ref,kABPersonEmailProperty);

NSArray *emails = (__bridge_transfer NSArray*)ABMultiValueCopyArrayOfAllValues(emailRef);

//individual emails can be iterated and found out like in code below.

for(int j = 0; j < [emailCount count]; j++)

{

NSString *ph = [emails objectAtIndex:j];

}

Similar to the Phone numbers, we can get the email labels using the below lines

CFStringRef unlocalizedLabel = ABMultiValueCopyLabelAtIndex(emailRef, j);

if (unlocalizedLabel)

{

     label = CFBridgingRelease(ABAddressBookCopyLocalizedLabel(unlocalizedLabel));

     CFRelease(unlocalizedLabel);

}

Getting Address components for a person contact

ABMultiValueRef addessRef= ABRecordCopyValue(ref,kABPersonAddressProperty);

NSArray *addressArray = (__bridge_transfer NSArray*)ABMultiValueCopyArrayOfAllValues(addessRef);

Now, we can iterate through the address array items and we can get the individual components for it. 

for(int j = 0; j < [addressArray count]; j++)

{

     Address *add = [[Address alloc] init];

     NSDictionary *addressDic = [addressArray objectAtIndex:j];

     if([addressDic objectForKey:@"City"])

         add.city =[addressDic objectForKey:@"City"];

     if([addressDic objectForKey:@"CountryCode"])

         add.country = [addressDic objectForKey:@"CountryCode"];

     if([addressDic objectForKey:@"State"])

         add.state = [addressDic objectForKey:@"State"];

     if([addressDic objectForKey:@"Street"])

         add.street = [addressDic objectForKey:@"Street"];

     if([addressDic objectForKey:@"ZIP"])

         add.zipCode = [addressDic objectForKey:@"ZIP"];

      contact.addresses addObject:add];

}

Reading Image Data: 

To know whether the person item having the image data, the ABPersonHasImageData API can be used. 

NSData *imageData = (__bridge NSData*)ABPersonCopyImageDataWithFormat(ref, kABPersonImageFormatThumbnail);

image = [UIImage imageWithData:imageData];

if(image)

{

//do something with the image

}    

CFRelease((__bridge CFTypeRef)(imageData));
