的iOS：保存在數組字符串數據

Question

我正在開發的聯繫人列表中的應用程序，這樣我需要把聯繫人數據，並存儲在tableview中我做了如下

 - (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); 

      } 


     } 

目標得到的字符串格式的數據是名字和姓氏。我的問題是我需要將名字和姓氏中存在的數據保存到數組但是該數組存在for循環的一側。以便我將數組數據傳遞給表視圖。

Answer 1

1.選擇1：只要做一件事就可以在for循環中創建NSMutableDictionary。將所有（名字，姓氏等）存儲在其中。最後的for循環將其添加到數組中。 2.選項2：將聯繫人創建爲具有必需屬性的對象。見例如這裏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); 

    }
