我正在尝试在下面提到的委托回调中获取选定的电子邮件属性

-(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;
    }

但是，如果我选择链接联系人的电子邮件属性（有单个电子邮件），我会得到标识符为 0，因此我会得到主要联系人的第一个电子邮件 ID。例如：John - john@gmail.com john26@gmail.com Roger（关联联系人） - roger@gmail.com

当我选择 roger@gmail.com 时，我得到 john@gmail.com。

I have this same issue. I get the wrong email when I select accounts with multiple email addresses. When I loop through the selected 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);
}

... I get multiple occurrences of the same address, but some with null labels.

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

The workaround I will try is to filter out the null labels first, see if the ABMultiValueIdentifier 'fits', and if not revert to the null labels. Unless you have found something?

Edit: this works for me.

    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);
    }
