如果要显示属于选项卡1的屏幕A，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)
    }
}
