AddressBook API问题 - NSInternalInconsistencyException

标签: iphone objective-c addressbook

我的情况如下:

我们正在创建一个应用程序(其中包括)显示Exchange中的公共文件夹中的数据。我们希望我们的iPhone应用程序显示默认情况下iPhone之类的联系人(如Apple的AddressBook应用程序),因此我们正在使用AddressBook API。但是,我们不打算在iPhone上保存任何显示的联系人,它只会用于在Exchange公共文件夹中显示联系人。

当我们要显示联系人记录时,我们使用'pushViewController'方法来显示'ABUnknownPersonViewController'。在代码中,我们使用ABPersonCreate()方法创建ABRecordRef对象。部分工作正常,我看到标题中显示的名称和其他详细信息(图片占位符旁边)。但是,一旦我添加了要在UITableViewCell布局中显示的任何细节(如电话,地址等),它就不会显示出来。更糟糕的是,一旦我第二次加载ABPersonViewController并且正在调用'setDisplayedPerson:'方法,应用程序崩溃了。注意:第一次加载时很好,但它没有显示应该在UITableViewCells中显示的数据。

我收到以下错误消息:

这是我的代码的一部分:

 ABRecordRef person = ABPersonCreate();

 if (person) {
      ABRecordSetValue(person, kABPersonLastNameProperty, @"Schreurs", NULL);
      ABRecordSetValue(person, kABPersonFirstNameProperty, @"Wolfgang", NULL);
      ABRecordSetValue(person, kABPersonOrganizationProperty, @"Webstate", NULL);          
      ABMultiValueRef phone = ABMultiValueCreateMutable(kABStringPropertyType);

      if (phone) {
           ABMultiValueAddValueAndLabel(phone, @"06 123 432 23", kABPersonPhoneMobileLabel, NULL);
           ABRecordSetValue(person, kABPersonPhoneProperty, phone, NULL);               
           CFRelease(phone);
      }

      [self setUnknownPersonViewDelegate:self];
      [self setDisplayedPerson:person];     

      CFRelease(person);
 }

答案 0 :(得分:0)

我找到了解决这个问题的方法。显然,在视图控制器中创建person(ABRecordRef)对象并不是一个好方法。而是在加载ABUnknownViewController之前创建人员。在加载ABUnknownViewController之前还要调用[setDisplayedPerson:]。这样行和部分就可以正确初始化,不再有任何不一致的例外。
