How to force view controller orientation in iOS 8?

Question

Before iOS 8, we used below code in conjunction with supportedInterfaceOrientations and shouldAutoRotate delegate methods to force app orie

Answer 1

This way work for me in Swift 2 iOS 8.x:

PS (this method dont require to override orientation functions like shouldautorotate on every viewController, just one method on AppDelegate)

Check the "requires full screen" in you project general info.

So, on AppDelegate.swift make a variable:

var enableAllOrientation = false

So, put also this func:

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
        if (enableAllOrientation == true){
            return UIInterfaceOrientationMask.All
        }
        return UIInterfaceOrientationMask.Portrait
}

So, in every class in your project you can set this var in viewWillAppear:

override func viewWillAppear(animated: Bool)
{
        super.viewWillAppear(animated)
        let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
        appDelegate.enableAllOrientation = true
}

If you need to make a choices based on the device type you can do this:

override func viewWillAppear(animated: Bool)
    {
        super.viewWillAppear(animated)
        let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
        switch UIDevice.currentDevice().userInterfaceIdiom {
        case .Phone:
        // It's an iPhone
           print(" - Only portrait mode to iPhone")
           appDelegate.enableAllOrientation = false
        case .Pad:
        // It's an iPad
           print(" - All orientation mode enabled on iPad")
           appDelegate.enableAllOrientation = true
        case .Unspecified:
        // Uh, oh! What could it be?
           appDelegate.enableAllOrientation = false
        }
    }
