Orientation support in single view controller swift 5

Question

I need to orientation support in single view controller

I try but did not work. Right now orientation in whole app.

override func viewDidLoad() {
    super.viewDidLoad()

    self.lockOrientation()
}

func lockOrientation() {
    let orientationValue = UIInterfaceOrientation.portrait.rawValue
    UIDevice.current.setValue(orientationValue, forKey: "orientation")
}

override var shouldAutorotate: Bool {
    return false
}

override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    return .portrait
}

override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
    return .portrait
}

That `UIDevice` line is a bad idea. It's a crash waiting to happen. — rmaddy, Jun 03 '19 at 05:00

Put the below code in AppDelegate

Keep Device Orientation as Portrait only from Project General settings

var restrictRotation: Bool = true

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
    if restrictRotation {
        return .portrait
    } else {
        return .all
    }
}

Put below code in which you want to allow/disable orientation.

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    self.restrictRotation(false) //TRUE TO RESTRICT ORIENTATION && FALSE TO ALLOW ORIENTATION
}

func restrictRotation(_ restriction: Bool) {
    let appDelegate = UIApplication.shared.delegate as? AppDelegate
    appDelegate?.restrictRotation = restriction
}

@bmjohns answer updated version

Swift 5

// set orientations you want to be allowed in this property by default
var orientationLock = UIInterfaceOrientationMask.all

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
        self.lockOrientation()
        return true
}

func unlockOriention () {
    self.orientationLock = .all
}

func lockOrientation() {
    self.orientationLock = .portrait
}

SecondViewController.swift

While support orientation

override func viewDidLoad() {
        super.viewDidLoad()
        let appDelegate = UIApplication.shared.delegate as! AppDelegate
        appDelegate.unlockOriention()
    }
