Question

我正在尝试获取iOS（5.0 +）上的地址簿条目的名称和出生日期，我找到了documentation和{{{{}}这样做的方法3}}。但我总是得到标题中提到的所有'kAB ...'常量的错误，虽然我确定我在项目中链接了两个库AddressBook和AddressBookUI。

有谁知道我做错了什么？

这是我的代码：

#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>

//其他一些代码......

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person {

    NSString *name;

    if ((NSString *)ABRecordCopyValue(person, kABNicknameProperty) != nil) {
        name = (NSString *)ABRecordCopyValue(person, kABNicknameProperty);
    } else if ((NSString *)ABRecordCopyValue(person, kABFirstNameProperty) != nil) {
        name = (NSString *)ABRecordCopyValue(person, kABFirstNameProperty);
    } else if ((NSString *)ABRecordCopyValue(person, kABLastNameProperty) != nil) {
        name = (NSString *)ABRecordCopyValue(person, kABLastNameProperty);
    }

    int birthYear;
    if ((NSDate *)ABRecordCopyValue(person, kABBirthdayProperty) != nil) {
        NSDate *birthDate = (NSDate *)ABRecordCopyValue(person, kABBirthdayProperty) != nil;
        NSCalendar *cal = [[NSCalendar alloc] init];
        NSDateComponents *components = [cal components:0 fromDate:birthDate];
        birthYear = [components year];
    }

    // do something with name and birth year
    [self dismissModalViewControllerAnimated:YES];

    return NO;
}

看起来您使用的常量特定于Mac OS X.其版本ABRecordCopyValue的iOS文档会导致kABPersonNicknameProperty等常量名称。

在iOS AddressBook中使用未声明的标识符'kABNicknameProperty' - 为什么？
