始終以縱向顯示視圖控制器[iOS]

Question

有沒有一種方法可以始終顯示縱向視圖控制器？ 例如，如果我處於風景模式，而主頁按鈕位於左側，則視圖控制器從左側顯示。 總是相對於視圖從底部顯示

//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()
    })
}
