推荐答案

按照此步骤操作，您将获得结果

步骤1:-，在安装广告连播后分配"ScrollingNavigationController"是导航控制器的类

Step1:- after install pod assign "ScrollingNavigationController" is class to navigation controller

第2步:- viewdidAppear()方法调用

Step2:- viewdidAppear() Method call

override func viewDidAppear(_ animated: Bool) {
            super.viewDidAppear(animated)
            if let navigationController = self.navigationController as? ScrollingNavigationController {
                navigationController.followScrollView(tableview, delay: 0.0, followers: [NavigationBarFollower(view: view, direction: .scrollUp)])
                navigationController.scrollingNavbarDelegate = self
            }
        }

第3步:- ScrollingNavigationControllerDelegate方法调用

Step3:- ScrollingNavigationControllerDelegate method call

extension ViewController: ScrollingNavigationControllerDelegate {
    func scrollingNavigationController(_ controller: ScrollingNavigationController, willChangeState state: NavigationBarState) {
        view.needsUpdateConstraints()
    }
}
