我正在单击一个按钮，然后推到塔巴尔控制器。

当我单击按钮时，它仅转到第一个选项卡，无论我在准备区域的准备中投入了什么号码。

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        
        let barViewControllers = segue.destination as! UITabBarController
            let nav = barViewControllers.viewControllers![2] as! UINavigationController
        let destinationViewController = nav.topViewController! as UIViewController
    }

它应该去的是具有棕色背景（数字2，第三个选项卡）

原文

I am clicking a button and pushing to a TabBar Controller.

When I click the button it goes to the first tab only, no matter what number I put in the prepare for segue area.

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        
        let barViewControllers = segue.destination as! UITabBarController
            let nav = barViewControllers.viewControllers![2] as! UINavigationController
        let destinationViewController = nav.topViewController! as UIViewController
    }

The one it should go to is the one with the brown background (Number 2, Third Tab)
