Push推送获取的token的变化

在iOS 13的系统版本中，token的格式发生了变得，导致不能按照iOS13之前的处理方法去处理然后再上传服务器。

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    DBLOG_FUN;
   NSString *_deviceToken = @"";
   if (@available(iOS 13.0, *)) {
      if (![deviceToken isKindOfClass:[NSData class]]) return;
      const unsigned *tokenBytes = [deviceToken bytes];
      _deviceToken = [NSString stringWithFormat:@"%08x%08x%08x%08x%08x%08x%08x%08x",
                            ntohl(tokenBytes[0]), ntohl(tokenBytes[1]), ntohl(tokenBytes[2]),
                            ntohl(tokenBytes[3]), ntohl(tokenBytes[4]), ntohl(tokenBytes[5]),
                            ntohl(tokenBytes[6]), ntohl(tokenBytes[7])];
      [[DataStore sharedStore] setDeviceToken:_deviceToken];
      DBLOG(@"_deviceToken：%@", _deviceToken);
   }else if([deviceToken.description length] > 0) {
        NSCharacterSet *set = [NSCharacterSet characterSetWithCharactersInString:@"<>"];
        _deviceToken = [deviceToken.description stringByTrimmingCharactersInSet:set];
        _deviceToken = [_deviceToken stringByReplacingOccurrencesOfString:@" " withString:@""];
        [[DataStore sharedStore] setDeviceToken:_deviceToken];
        DBLOG(@"_deviceToken：%@", _deviceToken);
    }
}
