Rubymotion UIView Orientation

Question

I currently have an ios app that I am writing in Rubymotion. I am trying to setup a UIViewController to display in portrait orientation always and not rotate to landscape. I cannot only specify portrait orientation in my rakefile as I need all orientaitons for other uiviewcontrollers. See below for my code:

class ConfirmationController < UIViewController

def viewDidLoad
    super
    self.view.backgroundColor = UIColor.blueColor
end

def shouldAutorotate
  true
end

def supportedInterfaceOrientations
  UIInterfaceOrientationMaskPortrait
end

def preferredInterfaceOrientationForPresentation
  UIInterfaceOrientationMaskPortrait
end

As you can see I am trying to set my preferredInterfaceOrientation but it is still changing to a landscape orientation when my device is rotated. Any ideas on how to set this up with Rubymotion?

Answer 1

After doing research I found where the issue came from was the UINavigationController being the rootView. I had to add a named controller that inherited from UINavigationController and then override the default UINavigation settings to change according to topViewController.

AppDelegate.rb

class TopNavController < UINavigationController

  def supportedInterfaceOrientations
    self.topViewController.supportedInterfaceOrientations
  end

  def preferredInterfaceOrientationForPresentation
    self.topViewController.preferredInterfaceOrientationForPresentation
  end
end

main_controller = MainScreenController.alloc.initWithNibName(nil, bundle: nil)
@window.rootViewController= TopNavController.alloc.initWithRootViewController(main_controller)

UIViewController

def shouldAutorotate
  true
end

def supportedInterfaceOrientations
  UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight
end

def preferredInterfaceOrientationForPresentation
  UIInterfaceOrientationLandscapeLeft
end
