Question

有许多应用程序与其后端服务器进行AddressBook同步，以交叉检查AddressBook中的哪些联系人正在使用他们的应用程序，以及需要将哪些用户邀请到他们的应用程序。

这是第一次可以进行完全同步，但之后它不应该是完全同步。

我的第一个问题是，将完整AddressBook与后端服务器同步的最佳方法是什么？

第二个问题是，如何同步仅最近修改过的联系人？

如果有任何示例应用程序或教程请与我分享。

提前致谢。

Answer 1

您好我也在研究相同的概念。

首先，我没有任何与您分享的教程。但是我在申请中正在做什么，我正在与你分享整个流程。

当应用程序第一次运行时，我将获取所有联系号码并发送到服务器。

但是当任何联系人修改时我只发送修改过的联系电话号码。

修改联系人后，您将收到来自地址簿的回电。每个联系人都会有特定的记录ID

夫特

typealias ABExternalChangeCallback = CFunctionPointer＆lt;（（ABAddressBook！，CFDictionary！，UnsafeMutablePointer） - ＆gt; Void）＆gt;

通过此属性，您可以了解最近修改了联系人的时间。

ABRecordCopyValue（record，kABPersonModificationDateProperty）.takeRetainedValue（）为？的NSDate

因此，您可以检查最近修改过的联系号码，然后再将这些联系人发送到服务器。

我希望它可以帮到你！

谢谢

从地址簿中获取所有电话号码作为格式化字符串，并将此字符串发布到网络服务器。这样可以很容易地在短时间内发送所有联系人。在网络服务器端，您可以编码将电话号码拆分为单独的号码，并检查具有相同号码的用户。

 -(NSString *)getPhoneContactAsSingleString
 {
   NSString *numberString=[NSString new];
   numberString=@"";

   CFErrorRef *error = nil;
   ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, error);
   __block BOOL accessGranted = NO;

   if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6

     dispatch_semaphore_t sema = dispatch_semaphore_create(0);
     ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
     accessGranted = granted;
     dispatch_semaphore_signal(sema);
     });
     dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);

     }
     else { // we're on iOS 5 or older
     accessGranted = YES;
   }
  if (accessGranted) {
  #ifdef DEBUG

                NSString *phoneNumber = (__bridge NSString *) phoneNumberRef;

                }



                if(phoneNumber.length!=0){
                    [phoneNumbers addObject:phoneNumber];
                    [numberNameDictionary setObject:name forKey:phoneNumber];
                    //NSLog(@"[%@]   -->   [%@]",orginal_phonenumber,phoneNumber);
                    numberString=[NSString stringWithFormat:@"%@%@,",numberString,phoneNumber];
                }

            }

{

#ifdef DEBUG
    NSLog(@"Cannot fetch Contacts :( ");
#endif

}

return numberString;
}

清理电话号码

-(NSString *)clean_phonenumber:(NSString *)number with_string:(NSString *)string
{
   NSArray *numberStrips           = [number componentsSeparatedByString:string];
   NSString *cleanNumber           = @"";
   for (NSString *eachString in numberStrips) {
      cleanNumber                 = [NSString stringWithFormat:@"%@%@", cleanNumber, eachString];
   }
   return cleanNumber;
}

只需检查方法

NSLog(@"%@",[self getPhoneContactAsSingleString]);
