始终从肖像[iOS]呈现视图控制器

Question

有没有办法始终从肖像呈现视图控制器？例如，如果我处于横向模式，左侧是主页按钮，则视图控制器从左侧显示。它总是从相对于视图的底部呈现

//When button is pressed
let viewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "viewContoller") as! CustomViewController
self.present(viewController, animated: true, completion: nil)

//App delegate
func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
    return .all  
}

Answer 1

override func viewDidLoad() {
    super.viewDidLoad()

    UIView.performWithoutAnimation({
        let value = UIInterfaceOrientation.portrait.rawValue
        UIDevice.current.setValue(value, forKey: "orientation")

        UIViewController.attemptRotationToDeviceOrientation()
    })
}
