iphone - 为联系人设置地址簿图像似乎不起作用

Question

我正在尝试使用下面的代码设置联系人图像。我没有看到任何错误，并且图像没有保存到地址簿中的联系人条目中。请帮忙!我一定做错了什么......

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
{
[abcontroller setDisplayedPerson:person];

UIImage *im = [UIImage imageNamed:@"image1.jpg"];
NSData *dataRef = UIImagePNGRepresentation(im);
CFErrorRef error;
ABAddressBookRef addressBook = ABAddressBookCreate(); 

NSLog(@"Error:",error);
    if (ABPersonSetImageData(person, (CFDataRef)dataRef, &error))
    {
        NSLog(@"Set contact photo %@", error);
        if (ABAddressBookHasUnsavedChanges(addressBook))
        {
            NSLog(@"Changes made to address book");
        }
        else {
            NSLog(@"No changes made to address book");
        }

        if (ABAddressBookSave(addressBook, &error))
        {
            NSLog(@"Saved");

        }
        else {
            NSLog(@"Not saved");
        }


    }
    else {
        NSLog(@"Error saving contact photo %@", error);
    }
ABAddressBookSave(addressBook, &error);

[self dismissModalViewControllerAnimated:YES];    

return NO;
}

这是我的输出日志:

2010-01-17 21:58:35.465 Error:
2010-01-17 21:58:35.504 Set contact photo <ABPeoplePickerNavigationController: 0x19e9b0>
2010-01-17 21:58:43.497 No changes made to address book
2010-01-17 21:58:44.724 Saved

我不确定为什么错误对象会记录为 ABPeoplePickerNavigationController 对象？

Answer 1

所有这些答案都不起作用。您应该简单地更改代码行:

ABAddressBookRef addressBook = ABAddressBookCreate(); 

至:

ABAddressBookRef addressBook = [peoplePicker addressBook];

这样您就可以获得对“人”所属的“地址簿”的引用。
