Question

我正在尝试从地址簿中选择用户想要的电子邮件ID。当用户选择工作电子邮件或家庭电子邮件时，应将相应的值添加到变量中。有什么建议吗？下面是我的代码：

-(BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{
if(property == kABPersonEmailProperty){
    CFStringRef value, label;
    ABMutableMultiValueRef multi = ABRecordCopyValue(person, kABPersonEmailProperty);
    CFIndex count = ABMultiValueGetCount(multi);
    if (count == 1)
    {
        value = ABMultiValueCopyValueAtIndex(multi, 0);
        email = (__bridge NSString*) value;
        NSLog(@"self.emailID   %@",email);
        CFRelease(value);
    }
    else
    {

        for (CFIndex i = 0; i < count; i++)
        {
            label = ABMultiValueCopyLabelAtIndex(multi, i);
            value = ABMultiValueCopyValueAtIndex(multi, i);
                            // check for Work e-mail label
            if (CFStringCompare(label, kABWorkLabel, 0) == 0)
            {
                email = (__bridge NSString*) value;
                NSLog(@"self.emailID   %@",email);
                NSLog(@"%@",(__bridge NSString *)label);

            }

            if(CFStringCompare(label, kABHomeLabel, 0) == 0)
            {
                email = (__bridge NSString*) value;
                NSLog(@"self.emailID   %@",email);
            }

            CFRelease(label);
            CFRelease(value);
        }
    }
    CFRelease(multi);
    [self displayPerson:person];

}else{
    UIAlertView *testAlert = [[UIAlertView alloc] initWithTitle:@"alert" message:@"Please choose a valid email" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"Cancel", nil];
    testAlert.tag = 100;
    [testAlert show];
}


  return NO;
}
