iOS开发- 添加地址从通讯录中选择添加（firstName，lastName真机为nil，模拟器正常）

在使用下面代码之前，需要先引入：
#import <AddressBookUI/ABPeoplePickerNavigationController.h>
#import <AddressBook/ABPerson.h>
#import <AddressBookUI/ABPersonViewController.h>
遵守ABPeoplePickerNavigationControllerDelegate协议
#pragma mark - addReceiverBtnAction
- (void)addReceiverBtnAction
{
//点击➕触发事件，记得plist设置允许访问手机通讯录，不多说了。
    ABPeoplePickerNavigationController *nav = [[ABPeoplePickerNavigationController alloc] init];
    nav.peoplePickerDelegate = self;
    //这个方法是在iOS8.0时才出现的,在其后要增加if中的代码，否则点击联系人后会直接dismiss，错误信息如下：
    //[App] if we're in the real pre-commit handler we can't actually add any new fences due to CA restriction
    if([[UIDevice currentDevice].systemVersion floatValue]>=8.0){
        nav.predicateForSelectionOfPerson = [NSPredicate predicateWithValue:false];
    }
    [self presentViewController:nav animated:YES completion:nil];
}
//此处为选择通讯录联系人的代理回调
#pragma mark - ABPeoplePickerNavigationControllerDelegate
//取消选择
- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker
{
    [peoplePicker dismissViewControllerAnimated:YES completion:nil];
}
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier {
    ABMultiValueRef phone = ABRecordCopyValue(person, kABPersonPhoneProperty);
    long index = ABMultiValueGetIndexForIdentifier(phone,identifier);
    NSString *phoneNO = (__bridge NSString *)ABMultiValueCopyValueAtIndex(phone, index);
    //有些手机号码带@“+86”，所以从第三位取
    if ([phoneNO hasPrefix:@"+"]) {
        phoneNO = [phoneNO substringFromIndex:3];
    }
    //去除手机号中间的@“-”
    phoneNO = [phoneNO stringByReplacingOccurrencesOfString:@"-" withString:@""];
    //这里的firstName和lastName指的是姓氏和名字，添加到通讯录时会有，但是这里有一个问题，博主在iOS10.3的系统上模拟器添加成功，但是在真机上这两个参数为nil，很匪夷所思的问题，好在有另一个方法，获取全名，如下anFullName：
    NSString *firstName=(__bridge NSString *)(ABRecordCopyValue(person, kABPersonFirstNameProperty));
    NSString *lastName=(__bridge NSString *)(ABRecordCopyValue(person, kABPersonLastNameProperty));
    [peoplePicker dismissViewControllerAnimated:YES completion:nil];
    CFStringRef anFullName = ABRecordCopyCompositeName(person);
    UITextField *address_contentField = [self.view viewWithTag:100];
    UITextField *address_contentField1 = [self.view viewWithTag:101];
    NSLog(@"%@%@---%@",firstName,lastName,anFullName);
    if (phoneNO) {
        address_contentField1.text = phoneNO;
        addressMobile = phoneNO;
    }
    else
        address_contentField1.text = @"";
    if (anFullName) {
        address_contentField.text = [NSString stringWithFormat:@"%@",anFullName];
        addressName = (__bridge NSString *)(anFullName);
    }
    else
        address_contentField.text = @"";
}
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person
{
    ABPersonViewController *personViewController = [[ABPersonViewController alloc] init];
    personViewController.displayedPerson = person;
    [peoplePicker pushViewController:personViewController animated:YES];
}
到这里并没有结束，除了获取这些个参数外，也许满足了大部分人的需求，但是你不知道的是，我们还可以获取一些别的东西，我们知道通讯录并不只是姓名和电话，还有组织，工作，部门之类的信息，如果设置齐全，是可以一并获取的，方法参考下面：
// Property keys

AB_EXTERN const ABPropertyID kABPersonEmailProperty AB_DEPRECATED("use CNContact.emailAddresses");                              // Email(s) - kABMultiStringPropertyType
AB_EXTERN const ABPropertyID kABPersonBirthdayProperty AB_DEPRECATED("use CNContact.birthday");                                 // Birthday associated with this person - kABDateTimePropertyType
AB_EXTERN const ABPropertyID kABPersonNoteProperty AB_DEPRECATED("use CNContact.note");                                         // Note - kABStringPropertyType
AB_EXTERN const ABPropertyID kABPersonCreationDateProperty AB_DEPRECATED("");                                                   // Creation Date (when first saved)
AB_EXTERN const ABPropertyID kABPersonModificationDateProperty AB_DEPRECATED("");                                               // Last saved date
// Addresses
AB_EXTERN const ABPropertyID kABPersonAddressProperty AB_DEPRECATED("use CNContact.postalAddresses");                           // Street address - kABMultiDictionaryPropertyType
//这些都是系统自带的一些属性，学习的小伙伴可以一个个替换来查看。
