Question

我是iphone开发的新手。我正在开发应用程序，我需要从地址簿中获取联系人详细信息，如姓名，电子邮件ID，电话号码以编程方式。并且这些值将存储在数组中，我们做得很好，但问题是即使是null联系人正在添加意味着如果某个人只有名称而没有电子邮件ID，那么如何检查空值不被添加。这是我正在使用的代码。

ABRecordRef ref;
ABAddressBookRef m_addressbook = ABAddressBookCreate();

CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(m_addressbook);
CFIndex nPeople = ABAddressBookGetPersonCount(m_addressbook);
NSLog(@" n people count values %ld",nPeople);

for (int i=0; i<nPeople; i++)
{ 
    AFContacts *contactOfAPerson = [[AFContacts alloc] init];
    ref = CFArrayGetValueAtIndex(allPeople,i);
    [contactOfAPerson setEmail:(NSString *)ABRecordCopyValue(ref, kABPersonEmailProperty)];
    [contactOfAPerson setFirstName:(NSString *)ABRecordCopyValue(ref, kABPersonFirstNameProperty)];
    //[contactOfAPerson setPhoneNumber:(NSString *)ABRecordCopyValue(ref, kABPersonPhoneMobileLabel)];
    [contactList addObject:contactOfAPerson];
    [contactOfAPerson release];
}
CFRelease(ref);
}

Answer 1

如果我理解正确，您不希望将没有电子邮件地址的联系人添加到阵列。您可以尝试使用if条件将联系人添加到数组

ABMultiValueRef emailAddresses = ABRecordCopyValue(ref, kABPersonEmailProperty);

if (ABMultiValueGetCount(emailAddresses) > 0)
{
   [contactOfAPerson setEmail:(NSString *)ABRecordCopyValue(ref, kABPersonEmailProperty)];
   [contactOfAPerson setFirstName:(NSString *)ABRecordCopyValue(ref, kABPersonFirstNameProperty)];
   [contactList addObject:contactOfAPerson];
}
