iOS地址簿：来自NSString值的联系人姓名

Question

我正在尝试从我的应用添加联系人到地址簿。我的代码效果很好，但我希望联系人名称是NSString的值。我试图用代码的名称替换代码中的@“David”，但它似乎不起作用。

CFErrorRef error = nil;
ABAddressBookRef iPhoneAddressBook = ABAddressBookCreate();
ABRecordRef newPerson = ABPersonCreate();
ABRecordSetValue(newPerson, kABPersonFirstNameProperty,@"David", nil);
ABRecordSetValue(newPerson, kABPersonLastNameProperty,@"Olsen", nil);

//Add my phone number

ABMutableMultiValueRef phoneNumber = ABMultiValueCreateMutable(kABStringPropertyType);
ABMultiValueAddValueAndLabel(phoneNumber,
                             @"095", kABPersonPhoneMainLabel, nil);
ABRecordSetValue(newPerson, kABPersonEmailProperty, phoneNumber, nil);


//Finally saving the contact in the address book
ABAddressBookAddRecord(iPhoneAddressBook, newPerson, &error);
ABAddressBookSave(iPhoneAddressBook, &error);
if (error != NULL)
{
    NSLog(@"Saving contact failed.");
}


NSLog(@"Contact saved.");

}

你必须使用CFStringRef，所以__bridge你的NSString

NSString *name = @David";
ABRecordSetValue(newPerson, kABPersonFirstNameProperty,(__bridge  CFStringRef) name, nil);
