objective-cの連絡先のアルファベットインデックス付きuitableviewを設定するにはどうすればよいですか？

Question

私はフォーマット以下のような私の電話帳からデータを取得しています：iOSの連絡先帳ごとにインデックス作成のためのこの方法のために使用するには、このデータを使用するにはどうすればよい

私はあなたがすべての連絡先を取得する方法を知っているが、アレイ内のすべての連絡先を取得するために、このメソッドを使用していけない： -

- (NSMutableArray *)getContactDetails:(NSString *)keyValue{ 


    ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL); 

    [self accessPermissionToAllowContacts:addressBook]; 

    NSMutableArray *allContacts = [[NSMutableArray alloc] init]; 

    CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook); 

    for(int i = 0; i < ABAddressBookGetPersonCount(addressBook); i++) 
    { 
     ABRecordRef ref = CFArrayGetValueAtIndex(allPeople, i); 

     //Using this we get only those contacts details which contact has address 

     ABMultiValueRef addressRef = ABRecordCopyValue(ref, kABPersonPhoneProperty); 


     if (ABMultiValueGetCount(addressRef) > 0) { 

      NSDictionary * contactData = [self singleContactDetail:ref]; 
      [allContacts addObject:contactData]; 
     } 
    } 

    return allContacts; 
} 

はその後、アレイへの辞書に変換のために、このメソッドを使用します -

- (NSDictionary *)singleContactDetail:(ABRecordRef)person { 

    // Initialize a mutable dictionary and give it initial values. 

    NSMutableDictionary *contactInfoDict = [[NSMutableDictionary alloc] init]; 

    // Use a general Core Foundation object. 

    CFTypeRef generalCFObject = ABRecordCopyValue(person, kABPersonFirstNameProperty); 

    // Get the first name. 

    if (generalCFObject) { 

     [contactInfoDict setObject:(__bridge NSString *)generalCFObject forKey:@"firstName"]; 


     CFRelease(generalCFObject); 
    } 

    // Get the last name. 

    generalCFObject = ABRecordCopyValue(person, kABPersonLastNameProperty); 

    if (generalCFObject) { 

     [contactInfoDict setObject:(__bridge NSString *)generalCFObject forKey:@"lastName"]; 

     CFRelease(generalCFObject); 
    } 

    NSString* mobileLabel; 

    ABMultiValueRef phones =(__bridge ABMultiValueRef)((__bridge NSString*)ABRecordCopyValue(person, kABPersonPhoneProperty)); 

    for(CFIndex j = 0; j < ABMultiValueGetCount(phones); j++) { 

     mobileLabel = (__bridge NSString*)ABMultiValueCopyLabelAtIndex(phones, j); 

     if(j==0) 
     { 
      [contactInfoDict setObject:(__bridge NSString*)ABMultiValueCopyValueAtIndex(phones, j) forKey:@"HomePhoneNo"]; 
     } 

     if(j==1) 
     { 
      [contactInfoDict setObject:(__bridge NSString*)ABMultiValueCopyValueAtIndex(phones, j) forKey:@"WorkPhoneNo"]; 

     } 

     if([mobileLabel isEqualToString:(NSString *)kABPersonPhoneMainLabel]) 

     { 

      [contactInfoDict setObject:(__bridge NSString*)ABMultiValueCopyValueAtIndex(phones, j) forKey:@"MainPhoneNo"]; 

     } 

     if([mobileLabel isEqualToString:(NSString *)kABPersonPhoneMobileLabel]) 
     { 

      [contactInfoDict setObject:(__bridge NSString*)ABMultiValueCopyValueAtIndex(phones, j) forKey:@"MobileNo"]; 

     } 

     if ([mobileLabel isEqualToString:(NSString*)kABPersonPhoneIPhoneLabel]) 
     { 
      [contactInfoDict setObject:(__bridge NSString*)ABMultiValueCopyValueAtIndex(phones, j) forKey:@"iPhoneNo"]; 
     } 

    } 

    return contactInfoDict; 
}
