在Tabbar中选中 3. tabbar item按照顺序E -> D -> A

App 会记住 1. tabbar item 上的 D 屏幕。我想要打开“A”屏幕。

下面的代码；

D View Controller :

        if let navController = self.tabBarController?.viewControllers?[0] as? UINavigationController{
            if let mapController = navController.childViewControllers.first as? MapViewController{
                self.tabBarController?.selectedIndex = 0
                mapController.zoomToGeo(X: Double(PhotoItemArraySelected[0].photoLon!)!, Y: Double(PhotoItemArraySelected[0].photoLat!)!,TesisAdi: PhotoItemArraySelected[0].photoName)

            }
        }

        dismiss(animated: true, completion: nil)
   }

如果要显示属于选项卡1的屏幕A，并且屏幕A看起来是MapViewController:

if let navController = self.tabBarController?.viewControllers?[0] as? UINavigationController{
    if let mapController = navController.childViewControllers.first as? MapViewController{
        self.tabBarController?.selectedIndex = 0
        mapController.zoomToGeo(X: Double(PhotoItemArraySelected[0].photoLon!)!, Y: Double(PhotoItemArraySelected[0].photoLat!)!,TesisAdi: PhotoItemArraySelected[0].photoName)

        //add this line and to check if it works good or not.
        navController.popToViewController(mapController, animated: true)
    }
}
