当交互式弹出手势发生时,搜索栏会消失

我正在添加这样的搜索控制器:

        viewController.navigationItem.searchCOntroller= searchController
        viewController.navigationItem.hidesSearchBarWhenScrolling = false
        viewController.definesPresentatiOnContext= true
        searchController.dimsBackgroundDuringPresentation = false

        searchBarContainer.translatesAutoresizingMaskIntoCOnstraints= false
        searchBarContainer.heightAnchor.constraint(equalToConstant: 0).isActive = true

当尝试向右滑动以弹出当前viewController(此处激活交互式pop手势)但停留在同一个控制器上时,搜索栏就会消失.

viewController.navigationItem.searchController

保持添加搜索控制器,但它不可见.
