swift - 通过 TabbarController 和 NavigationController 进行导航。如何？

Question

我有这样的 Storyboard文件:enter image description here

当用户登录时，我使用以下命令进行segue:

 let storyboard = UIStoryboard(name: "Main", bundle: nil)
 let initialVC: UITabBarController = storyboard.instantiateViewController(withIdentifier: "loggedin") as! UITabBarController
 self.present(initialVC, animated: true, completion: nil)

并自动打开带有标识符“selectsaloon”的 View Controller ，但有时根据条件我需要转到带有标识符“searchparams”的 View Controller 。帮我找到解决办法

Answer 1

当条件发生时，您可以在 viewdidload 上为 selectsaloon 进行导航

    if (condition) {
  let storyboard = UIStoryboard(name: "Main", bundle: nil)
     let initialVC: UIVieWController = storyboard.instantiateViewController(withIdentifier: "searchparams") as! UIViewController
     self.navigationController.push(initialVC, animated: true)
 }
