接著上一篇如何存取iPhone 通訊錄裡的資料，接著就是要新增一筆資料寫入通訊錄了。其實很簡單，只要呼叫 ABPersonCreate(); 便可產生一筆空白資料，多項資料(MultiProperty)比單項資料(Property)多了一道處理程序；直接來看範例～
NSString *firstName, *lastName, ... ;
NSDictionary *emails;
...
//產生 AddressBook 物件
ABAddressBookRef addressBookObj = ABAddressBookCreateWithOptions(NULL, NULL);
//產生一筆空白聯絡人資料
ABRecord record = ABPersonCreate();
//處理單項資料 (property)
ABRecordSetValue(record, kABPersonFirstNameProperty, CFBridgingRetain(firstName) , nil);
ABRecordSetValue(record, kABPersonLastNameProperty, CFBridgingRetain(lastName) , nil);
//處理多項資料 (MultiProperty)
NSArray *allLabels = [emails allKeys];
ABMutableMultiValueRef multiValue = ABMultiValueCreateMutable(kABMultiStringPropertyType);
for(NSString *label in allLabels) {
NSString *value = [emails objectForKey:label];
ABMultiValueAddValueAndLabel(multiValue, CFBridgingRetain(value), CFBridgingRetain(label), NULL);
}
ABRecordSetValue(record, kABPersonEmailProperty, multiValue, nil);
//寫入&儲存
ABAddressBookAddRecord(addressBookObj,record,nil);
ABAddressBookSave(addressBookObj);
在上面的例子中，是直接產生一筆空白的聯絡人資料；若是換成即有存在的舊資料，也是可以的，但在處理多項資料時，若遇到已經存在的label，不可使用 ABMultiValueAddValueAndLabel，請改用 ABMultiValueReplaceValueAtIndex 去處理；
除了，直接寫入通訊錄外， framework 另外提供了預設的聯絡人的輸入UI，共有二套，一為 "ABNewPersonViewController"；另一為 "ABUnknownPersonViewController"；差別在於後者可以選擇覆寫即有的資料。
ABNewPersonViewController 的範例～
ABNewPersonViewController *newPersonVC = [[ABNewPersonViewController alloc] init];
ABRecordRef aNewRecord = ABPersonCreate();
newPersonVC.newPersonViewDelegate = self;
newPersonVC.addressBook = addressBookObj;
newPersonVC.displayedPerson = aNewRecord;
[currentNavigationViewController pushViewController:newPersonVC animated:YES];
ABNewPersonViewController 的範例～
ABUnknownPersonViewController *unknowPersonVC = [[ABUnknownPersonViewController alloc]init];
unknowPersonVC.unknownPersonViewDelegate = self;
unknowPersonVC.displayedPerson = aOldRecord;
unknowPersonVC.allowsAddingToAddressBook = YES;
unknowPersonVC.allowsActions = YES;
[currentNavigationViewController pushViewController:unknowPersonVC animated:YES];
