Addressbook链接器错误：体系结构i386的未定义符号 [英] Addressbook linker error: Undefined symbols for architecture i386

问题描述

当我使用 __ bridge_transfer 或 __ bridge ：

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker
      shouldContinueAfterSelectingPerson:(ABRecordRef)person 
{
    NSString* nameFirst = (__bridge_transfer NSString *)ABRecordCopyValue(person,
                                                   kABPersonFirstNameProperty);       
    NSString* nameLast = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
    _sight.contactName = [NSString stringWithFormat:@"%@ %@", nameFirst, nameLast];

    [self dismissModalViewControllerAnimated:YES];
    return NO;
}

以上代码产生以下错误：

Code above produces an error below:

添加了Addressbook和AddressbookUI框架......

Addressbook and AddressbookUI frameworks added...

推荐答案

好的，问题是Addressbook框架在我的项目中，但从Project - Summary tab - Linked Frameworks and Libraries中消失了。

OK, the problem was that Addressbook framework was in my project, but dissappeared from "Project"-"Summary tab"-"Linked Frameworks and Libraries".

在我添加框架后，所有问题都消失了。

After I added framework there all problems gone.
