地址簿 - 选择链接联系人的电子邮件

Question

我正在尝试在下面提到的委托回调中获取所选的电子邮件属性

-(BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier {
        if (property==kABPersonEmailProperty) {
            ABMultiValueRef emails = ABRecordCopyValue(person, kABPersonEmailProperty);
            if (ABMultiValueGetCount(emails) > 0) {
                NSString *email = (__bridge_transfer NSString*)
                ABMultiValueCopyValueAtIndex(emails, ABMultiValueGetIndexForIdentifier(emails,identifier));
                [recipientEmail setText:email];
                [peoplePicker dismissViewControllerAnimated:YES completion:nil];
            }
             CFRelease(emails);
        }
        return NO;
    }

.

但如果我选择链接联系人的电子邮件属性（有单个电子邮件），我将标识符获得为0，因此我得到了主要联系人的第一个电子邮件ID。 例如：John - John@gmail.com john26@gmail.com. Roger（Linked Contact） - roger@gmail.com

当我选择roger@gmail.com时，我会得到约翰@ gmail.com。

我有同样的问题。当我选择具有多个电子邮件地址的帐户时，我会得到错误的电子邮件。当我循环通过选定的abmutablemultivalueref ...

for (CFIndex ix = 0; ix < ABMultiValueGetCount(emails); ix++) {
   CFStringRef label = ABMultiValueCopyLabelAtIndex(emails, ix);
   CFStringRef value = ABMultiValueCopyValueAtIndex(emails, ix);
   NSLog(@"I have a %@ address: %@", label, value);
   if (label) CFRelease(label);
   if (value) CFRelease(value);
}

.

......我得到了多个相同的地址发生，但有些用空标签。

> I have a (null) address: john@home.com
> I have a _$!<Work>!$_ address: jsmith@work.com
> I have a _$!<Home>!$_ address: john@home.com

.

解决方法我将尝试首先过滤掉空标签，看看ABMultivalueIdentifier'适合'，如果不恢复为NULL标签。除非你找到了什么？

编辑：这适用于我。

    NSMutableArray *labeled = [NSMutableArray new];
    ABMutableMultiValueRef emails = ABRecordCopyValue(person, kABPersonEmailProperty);
    for (CFIndex ix = 0; ix < ABMultiValueGetCount(emails); ix++) {
        CFStringRef label = ABMultiValueCopyLabelAtIndex(emails, ix);
        CFStringRef value = ABMultiValueCopyValueAtIndex(emails, ix);
        if (label != NULL) {
            [labeled addObject:(NSString *)CFBridgingRelease(value)];
        }
        if (label) CFRelease(label);
        if (value) CFRelease(value);
    }
    NSString *email;
    if (labeled.count > identifier) {
        email = [labeled objectAtIndex:identifier];
    } else {
        CFStringRef emailRef = ABMultiValueCopyValueAtIndex(emails, identifier);
        email = (NSString *)CFBridgingRelease(emailRef);
    }
