从 iOS 中的共享链接打开应用程序后，我无法获取分支安装参数

如何解决从 iOS 中的共享链接打开应用程序后，我无法获取分支安装参数

我正在与 Branch.io 共享链接，但是当我从我的 didFinishLaunchingWithOptions 中的链接安装应用程序时，没有获取 Branch 参数。

[[Branch getInstance] initSessionWithLaunchOptions:launchOptions isReferrable:YES andRegisterDeepLinkHandler:^(NSDictionary * _Nullable params,NSError * _Nullable error) {
if (!error) {
            // params are the deep linked params associated with the link that the user clicked -> was re-directed to this app
            // params will be empty if no data found
            // ... insert custom logic here ...
            NSLog(@"branch params.description: %@",params.description);
            NSLog(@"branch params: %@",params);

            

        } else {
            NSLog(@"branch error: %@",error);
        }
    }];


branch params don't have the embedded properties in it,and also it cant detect it is installed from Link.

It always prints:
branch params: {
    "+clicked_branch_link" = 0;
    "+is_first_session" = 0;
}

我已经在 Project 中设置了所有关键信息和关联域。

这可能是什么原因，是否与ios版本有关？或分支sdk问题？ 提前致谢。
