-

Jan 14, 2018

• Set the orientation option on project settings ![project settings]({{ "/assets/posts/2018-01-14.png" | absolute_url }})
• In First, Set the orientation at AppDelegate {% highlight swift %} var enableAllOrientation = false func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask { if (enableAllOrientation == true){ return UIInterfaceOrientationMask.allButUpsideDown } return UIInterfaceOrientationMask.portrait } {% endhighlight %}

• Enable rotating orientation onto a specific viewController {% highlight swift %} override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated)

  JDFacade.app.enableAllOrientation = true }

override func viewWillDisappear(_ animated: Bool) { super.viewWillDisappear(animated)

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

JDFacade.app.enableAllOrientation = false

} {% endhighlight %}

• when back to the non-orientation viewController

{% highlight swift %} override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated)

  let rect = CGRect(x: 0, y: 0, width: 375, height: 667)
  if let wrapperView = self.tabBarController?.view.subviews[0].subviews[0] {
      wrapperView.frame = rect
  }

  UIViewController.attemptRotationToDeviceOrientation()

} {% endhighlight %}
