ios - 以编程方式导航到另一个 Storyboard上的 navigationcontroller 和 tabbarcontroller 内的 viewcontroller

Question

我需要以编程方式从另一个 Storyboard 转到 View Controller 。从这里开始很容易。但问题是:viewController 嵌入在导航 Controller 中，而这个嵌入到 tabBarController 中(见图)

我试过:

    let storyboard = UIStoryboard(name: "Inside", bundle: nil)

    let viewcontroller = storyboard.instantiateViewController(withIdentifier: "controller_id")
    let navigationController = UINavigationController(rootViewController: viewcontroller)

    self.present(navigationController, animated: true, completion: nil)

我得到的是:我转到正确的 Controller ，导航 Controller 工作，但没有 tabbarcontroller

另一个尝试:

    let storyboard = UIStoryboard(name: "Inside", bundle: nil)

    let tabbar = storyboard.instantiateViewController(withIdentifier: "tab_id")
    let navigationController = UINavigationController(rootViewController: tabbar)

    self.present(navigationController, animated: true, completion: nil)

在这种情况下，tabbar 可以工作，但没有 navigationcontroller。

然后...尝试第 3 种方法:

    let storyboard = UIStoryboard(name: "Inside", bundle: nil)
    let tabbar = storyboard.instantiateViewController(withIdentifier: "tab_id")
    let viewcontroller = storyboard.instantiateViewController(withIdentifier: "race_id")

    let navigationController = UINavigationController(rootViewController: tabbar)

    navigationController.pushViewController(viewcontroller, animated: false)

    self.present(navigationController, animated: true, completion: nil)

在这种情况下，行为很奇怪...我出现在正确的 Controller 中，但带有后退按钮。如果我单击我会转到相同的正确 Controller ...使用 tabbarcontroller...然后导航 Controller 消失...很好 :S

有没有办法以编程方式转到正确的 Controller 并开始使用标签栏和导航？

Answer 1

试试下面的代码:

var storyBoard = UIStoryboard(name: "SecondStoryboard", bundle: nil)
var tabbar: UITabBarController? = (storyBoard.instantiateViewController(withIdentifier: "tabbar") as? UITabBarController)
navigationController?.pushViewController(tabbar, animated: true)

我对 swift 的了解较少。上面的 Objective-C 代码是:

    UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"SecondStoryboard" bundle:nil];
    UITabBarController *tabbar = (UITabBarController *)[storyBoard instantiateViewControllerWithIdentifier:@"tabbar"];
    [self.navigationController pushViewController:tabbar animated:YES];
