如何以編程方式從通訊錄獲取聯繫人信息

Question

我是iphone開發新手。我正在開發應用程序，我需要從通訊錄中獲取聯繫人詳細信息，如名字，電子郵件ID，電話號碼編程。並且這些值將被存儲在數組中，iam表現良好，但問題是即使爲空的聯繫人也被添加，意味着如果某人只有名字並且沒有電子郵件ID，那麼如何檢查不添加空值。這是我正在使用的代碼。

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

如果我理解正確，您不想將沒有電子郵件地址的聯繫人添加到陣列。您可以嘗試使用，如果條件聯繫人添加到陣列

ABMultiValueRef emailAddresses = ABRecordCopyValue(ref, kABPersonEmailProperty); 

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

結帳這個最好是導入聯繫人及其所有細節
