ios - 如何使用电话号码在地址簿中搜索 ios

Question

我是 IOS 编程的新手。在我的简单应用程序中，我将名字、姓氏和电话号码存储在 NSMutableArray 中。我有一个 UITextfield，我可以在其中获取电话号码。我想根据手机号码搜索名字和姓氏。我正在存储名字、姓氏和电话不同可变数组中的数字，因此如何在存储的数组中搜索名字和姓氏。这是我的代码

     ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);

    _firstname = [[NSMutableArray alloc]init];
    _lastname = [[NSMutableArray alloc]init];
    _number = [[NSMutableArray alloc]init];
    _fullname = [[NSMutableArray alloc]init];
    _arrContacts = [[NSMutableArray alloc]init];
    if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {

        ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {                
            ABAddressBookRef addressBook = ABAddressBookCreate( );                
        });            
    }

    else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
        CFErrorRef *error = NULL;

        ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, error);

        CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);

        CFIndex numberOfPeople = ABAddressBookGetPersonCount(addressBook);

        for(int i = 0; i < numberOfPeople; i++) { 
            ABRecordRef person = CFArrayGetValueAtIndex( allPeople, i );                
            NSString *firstName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonFirstNameProperty));                
            NSString *lastName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonLastNameProperty));                
            if (firstName != nil) {
                [_firstname addObject:firstName];    
            }
            else{
                [_firstname addObject:@"Not Found"];
            }
            if (lastName != nil) {
                [_lastname addObject:lastName];
            }
            else{
                [_lastname addObject:@"Not Found"];
            }


            ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);                
            [[UIDevice currentDevice] name];                
            NSArray *numbers = (__bridge NSArray *)(ABMultiValueCopyValueAtIndex(phoneNumbers, 0));                
            if (numbers != nil) {                    
                [_arrContacts addObject:numbers];                    
                NSLog(@"Numbers:%@",_arrContacts); 
            }




            for (CFIndex i = 0; i < ABMultiValueGetCount(phoneNumbers); i++) {                    
                NSString *phoneNumber = (__bridge_transfer NSString *) ABMultiValueCopyValueAtIndex(phoneNumbers, i); 
                _addressBookNum = [_addressBookNum stringByAppendingFormat: @":%@",phoneNumber];                    
            }                
        }

        // NSLog(@"AllNumber:%@",_addressBookNum);

    }

    else {            
        // Send an alert telling user to change privacy setting in settings app            
    }

    CFRelease(addressBookRef);
    NSLog(@"This is Name: %@",_firstname);
    NSLog(@"This is LastName: %@",_lastname);
    NSLog(@"Number: %@",_arrContacts);    
}

请提出一些想法来做到这一点

与其将姓名、姓氏和数字保存在不同的数组中，不如将其存储在带有字典的单个数组中。假设 NSMutabelArray *细节创建具有三个值名称姓氏和数字的字典，并将此字典添加到数组中， 方便您进一步使用
