Список контактов с телефонами

Question

Я хотел бы получить (в iOS с использованием Objective-C) только те контакты, у которых есть номер телефона, но как я могу это сделать? Я пытаюсь сформировать предикат, как в коде ниже, но, очевидно, это не работает.

contacts = [contactStore unifiedContactsMatchingPredicate:[NSPredicate predicateWithFormat:@"phoneNumbers <> nil"] keysToFetch:KEYS error:nil]; 

Итак, каков правильный способ сделать это? Спасибо за любую помощь!

Answer 1

отфильтровывая контактов, которые не имеют номер телефона (или другое свойство) невозможно. В документации мы читаем:

CNContact Предикаты

Предикаты для соответствия контактов. Эти предикаты можно использовать только с CNContactStore и CNContactFetchRequest.

• predicateForContactsMatchingName: возвращает предикат, чтобы найти контакты, соответствующие указанному имени.
• predicateForContactsWithIdentifiers: возвращает предикат, чтобы найти контакты, соответствующие указанным идентификаторам.
• predicateForContactsInGroupWithIdentifier: возвращает предикат, чтобы найти контакты, являющиеся членами указанной группы.
• predicateForContactsInContainerWithIdentifier: возвращает предикат, чтобы найти контакты в указанном контейнере.

И дополнительно:

Составные сказуемые не поддерживаются.

Таким образом, единственный способ сделать фильтрацию - опустить добавление в массив результатов контактов без телефонных номеров. Это можно сделать, например, в блоке enumerateContactsWithFetchRequest.

Answer 2

использовать следующий метод и импортировать

#import <AddressBook/AddressBook.h> 
#import <Contacts/Contacts.h> 


-(void)contactsDetailsFromPhoneContactBook{ 
    CNContactStore *store = [[CNContactStore alloc] init]; 
    [store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) { 
     if (granted == YES) { 
      //keys with fetching properties 
      NSArray *keys = @[CNContactFamilyNameKey,CNContactGivenNameKey]; 
      NSString *containerId = store.defaultContainerIdentifier; 
      NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId]; 
      NSError *error; 
      NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error]; 
      if (error) { 
       NSLog(@"error fetching contacts %@", error); 
      } else { 
       NSString *fullName; 
       NSString *firstName; 
       NSString *lastName; 
       for (CNContact *contact in cnContacts) { 
        // copy data to my custom Contacts class. 
        firstName = contact.givenName; 
        lastName = contact.familyName; 
        if (lastName == nil) { 
         fullName=[NSString stringWithFormat:@"%@",firstName]; 
        }else if (firstName == nil){ 
         fullName=[NSString stringWithFormat:@"%@",lastName]; 
        } 
        else{ 
         fullName=[NSString stringWithFormat:@"%@ %@",firstName,lastName]; 
        } 
        [self.contactsArray addObject:fullName]; 

        NSLog(@"working or not %@",self.contactsArray); 
       } 

      } 
     } 
    }]; 
}

Используйте ниже код для извлечения контакта с именем и детали

#import <AddressBook/ABAddressBook.h> 
#import <AddressBookUI/AddressBookUI.h> 

-(NSMutableArray*)fetchContactList{ 
    ABAddressBookRef addressBook = ABAddressBookCreate();

     dispatch_semaphore_t semaphore = dispatch_semaphore_create(0); 

     ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) { 
      accessGranted = granted; 
      dispatch_semaphore_signal(semaphore); 
     }); 

     dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER); 
    } 

    else { // We are on iOS 5 or Older 
     accessGranted = YES; 
     [self getContactsWithAddressBook:addressBook]; 
    } 

    if (accessGranted) { 
     return [self getContactsWithAddressBook:addressBook]; 
    } 
    return [[NSMutableArray alloc] init];

     NSString* mobileLabel;

        [dOfPerson setValue:[Utility cleanedPhoneNumber:(__bridge NSString*)ABMultiValueCopyValueAtIndex(phones, j)] forKey:@"Phone"]; 
        break ; 
       }else{ 
        [dOfPerson setValue:[Utility cleanedPhoneNumber:(__bridge NSString*)ABMultiValueCopyValueAtIndex(phones, j)] forKey:@"Phone"]; 
       } 
      } 
     }else{ 
      NSLog(@"else"); 
      [arrWithoutPhoneContact addObject:[NSString stringWithFormat:@"%d",i]]; 
     } 


     //Contact Id 
     ABRecordID recordID = ABRecordGetRecordID(ref); 
     [dOfPerson setValue:[NSString stringWithFormat:@"%d",recordID] forKey:@"contactId"]; 

     [contactList addObject:dOfPerson]; 

    } 

    NSLog(@"Withot Phone %@", arrWithoutPhoneContact); 
    for (int j = 0; j < arrWithoutPhoneContact.count; j++) {
