Question

我想在我的应用程序中添加一个标签栏。我添加了标签栏的页面不断刷新自身。我的customAnimateRemindStyle3()函数一直在被调用。我该怎么办？

class MainTableViewController: UITableViewController, UITabBarControllerDelegate {
  override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)     
       self.present(AppDelegate.customAnimateRemindStyle3(implies: false), animated: false, completion: nil)   
  }
}

class AppDelegate: UIResponder, UIApplicationDelegate, UITabBarControllerDelegate {
static func customAnimateRemindStyle3(implies: Bool) -> ExampleNavigationController {
        let tabBarController = ESTabBarController()
        if let tabBar = tabBarController.tabBar as? ESTabBar {
            tabBar.itemCustomPositioning = .fillIncludeSeparator
        }
        let v1 = MainTableViewController()
        let v2 = MainTableViewController()
        let v3 = MainTableViewController()
        let v4 = MainTableViewController()
        let v5 = MainTableViewController()

        v1.tabBarItem = ESTabBarItem.init(ExampleAnimateTipsContentView3(), title: nil, image: UIImage(named: "home"), selectedImage: UIImage(named: "home_1"))
        v2.tabBarItem = ESTabBarItem.init(ExampleAnimateTipsContentView3(), title: nil, image: UIImage(named: "find"), selectedImage: UIImage(named: "find_1"))
        v3.tabBarItem = ESTabBarItem.init(ExampleAnimateTipsContentView3.init(specialWithAutoImplies: implies), title: nil, image: UIImage(named: "photo_big"), selectedImage: UIImage(named: "photo_big_1"))
        v4.tabBarItem = ESTabBarItem.init(ExampleAnimateTipsContentView3(), title: nil, image: UIImage(named: "favor"), selectedImage: UIImage(named: "favor_1"))
        v5.tabBarItem = ESTabBarItem.init(ExampleAnimateTipsContentView3(), title: nil, image: UIImage(named: "me"), selectedImage: UIImage(named: "me_1"))

        tabBarController.viewControllers = [v1, v2, v3, v4, v5]

        if let tabBarItem = v2.tabBarItem as? ESTabBarItem {
            DispatchQueue.main.asyncAfter(deadline: .now() + 2 ) {
                tabBarItem.badgeValue = "1"
            }
        }

        let navigationController = ExampleNavigationController.init(rootViewController: tabBarController)
        return navigationController
    }
}

之所以会这样，是因为您要在ExampleNavigationController的{{1}}上展示一个包含MainTableViewController的新ViewWillAppear

简单地说，您是递归，要求一遍又一遍地展示MainTableViewController

您可以在这里做

首先删除此行表格MainTableViewController

ViewWillAppear

然后在应用程序代理中显示self.present(AppDelegate.customAnimateRemindStyle3(implies: false), animated: false, completion: nil)以

开头

TabBarController

使用ESTabBarController添加标签栏
