Need help setting up an interface where rotation is fixed for most elements, but alert and sharing boxes auto-rotate with the device

Question

I\'m working with Xcode 7 and Swift 2. I am working on an interface with a camera preview layer and controls that display in a manner similar to the native iOS camera app. The c

Answer 1

Got it working. I needed to access presentedViewController.view to rotate the alert and share views.

//used to periodically trigger a check of orientation
var updateTimer: NSTimer?

//Checks if the device has rotated and, if so, rotates the controls. Also prompts the user that portrait orientation is bad.
func checkOrientation(timer: NSTimer) {
    //Array of the views that need to be rotated as the device rotates
    var viewsToRotate = [oneView, anotherView]

    //This adds the alert or sharing view to the list, if there is one
    if let presentedVC = presentedViewController?.view {
        viewsToRotate.append(presentedVC)
    }

    //Rotate all of the views identified above
    for viewToRotate in viewsToRotate {
        switch UIDevice.currentDevice().orientation {
        case UIDeviceOrientation.Portrait:
            viewToRotate.transform = CGAffineTransformMakeRotation(CGFloat(-M_PI_2))
        case UIDeviceOrientation.PortraitUpsideDown:
            viewToRotate.transform = CGAffineTransformMakeRotation(CGFloat(M_PI_2))
        case UIDeviceOrientation.LandscapeRight:
            viewToRotate.transform = CGAffineTransformMakeRotation(CGFloat(2 * M_PI_2))
        default:
            viewToRotate.transform = CGAffineTransformMakeRotation(CGFloat(0))
        }
    }
}
