首先LineSDK v5.8.1 v5.8.2
获取Line的授权登录成功，

 NSSet *permissions = [NSSet setWithObjects:
                              [LineSDKLoginPermission profile],
                              [LineSDKLoginPermission openID],
                          [LineSDKLoginPermission friends],
                          [LineSDKLoginPermission groups],
                              nil];
    [[LineSDKLoginManager sharedManager] loginWithPermissions:permissions inViewController:vc completionHandler:^(LineSDKLoginResult * _Nullable loginResult, NSError * _Nullable error) {
            if (error == nil) {
                
                if (!loginResult.userProfile.userID && [loginResult.userProfile.userID isEqualToString:@""]) {
                    if (self.failure)
                    {
                        self.failure(error);
                    }
                }else
                {
#####竟然让人不可思议的是连续走了两次
//                    [NSObject cancelPreviousPerformRequestsWithTarget:self];
//                    [self performSelector:@selector(lineSdkSuccess:) withObject:loginResult afterDelay:2];

不得已进行中止线程 

//后v5.9.0版本，更新后，貌似bug已经解决，仅仅一次，应该算是修复，希望后续不要有人也经历这个抓狂的BUG
                    if (loginResult.userProfile.userID && ![loginResult.userProfile.userID isEqualToString:@""]) {
                        HLSocialLoginInfo *info = [[HLSocialLoginInfo alloc]init];
