iOS：将字符串数据保存在数组中

Question

我正在开发联系人列表应用程序，因此我需要带上联系人数据并存储在我做的表格视图中，如下所示

     - (void)listPeopleInAddressBook:(ABAddressBookRef)addressBook
   {
     NSInteger numberOfPeople = ABAddressBookGetPersonCount(addressBook);
    contactList= CFBridgingRelease(ABAddressBookCopyArrayOfAllPeople(addressBook));

for (int i = 0; i < numberOfPeople; i++)
{
    ABRecordRef person = (__bridge ABRecordRef)contactList[i];

   firstName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonFirstNameProperty));
 lastName  = CFBridgingRelease(ABRecordCopyValue(person, kABPersonLastNameProperty));
    NSLog(@"Name:%@ %@", firstName, lastName);

    ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);

    CFIndex numberOfPhoneNumbers = ABMultiValueGetCount(phoneNumbers);
    for (CFIndex i = 0; i < numberOfPhoneNumbers; i++)
    {
        NSString *phoneNumber = CFBridgingRelease(ABMultiValueCopyValueAtIndex(phoneNumbers, i));
        NSLog(@"  phone is:%@", phoneNumber);
    }
         CFRelease(phoneNumbers);

           }


        }

旨在以字符串格式获取数据，即名字和姓氏。我的问题是我需要将名字和姓氏中存在的数据保存到数组但该数组存在于 for 之外环形 。这样我就可以将数组数据传递给表格视图。

Answer 1

1.option 1：只需做一件事，在 for 循环中创建 NSMutableDictionary。将所有（名字，姓氏等）存储在其中。最后 for 循环将其添加到数组中。 2.option 2：将联系人创建为具有所需属性的对象。请参阅此处的示例https://stackoverflow.com/questions/24552545/how-to-get-phonebook-contacts-from-ios-device

Answer 2

- (void)listPeopleInAddressBook:(ABAddressBookRef)addressBook
{

    NSInteger numberOfPeople = ABAddressBookGetPersonCount(addressBook);
    NSMutableArray * contactList= CFBridgingRelease(ABAddressBookCopyArrayOfAllPeople(addressBook));

    NSMutableArray *tableviewArray =[[NSMutableArray alloc] init]; // ADD This Line

    for (int i = 0; i < numberOfPeople; i++)
    {
        ABRecordRef person = (__bridge ABRecordRef)contactList[i];

        NSString *  firstName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonFirstNameProperty));
        NSString *  lastName  = CFBridgingRelease(ABRecordCopyValue(person, kABPersonLastNameProperty));
        NSLog(@"Name:%@ %@", firstName, lastName);




        ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);

        CFIndex numberOfPhoneNumbers = ABMultiValueGetCount(phoneNumbers);
        for (CFIndex i = 0; i < numberOfPhoneNumbers; i++)
        {
            NSString *phoneNumber = CFBridgingRelease(ABMultiValueCopyValueAtIndex(phoneNumbers, i));
            NSLog(@"  phone is:%@", phoneNumber);
        }

        [tableviewArray addObject:[NSDictionary dictionaryWithObjectsAndKeys:firstName , @"first_name" , lastName , @"last_name" , nil]]; // ADD This Line

        CFRelease(phoneNumbers);

    }
