Show UIAlertController over keyboard

Question

In iOS 8 and lower show a UIActionSheet when keyboard is presented will present the action sheet over the keyboard. With iOS 9 this is no longer the case.

Answer 1

Based on Leo Natan's answer, I've created a Swift extension for presenting an alert sheet over the keyboard.

In my brief testing, the alertWindow is deallocated after the alert is dismissed, I believe because there's no strong reference to it outside of the alert. This means there's no need to hide or deallocate it in your UIAlertActions.

extension UIAlertController {

    func presentOverKeyboard(animated: Bool, completion: (() -> Void)?) {

        let alertWindow = UIWindow(frame: UIScreen.mainScreen().bounds)

        // If you need a white/hidden/other status bar, use an appropriate VC.
        // You may not need a custom class, and you can just use UIViewController()
        alertWindow.rootViewController = whiteStatusBarVC()

        alertWindow.windowLevel = 10000001
        alertWindow.hidden = false

        // Set to a tint if you'd like
        alertWindow.tintColor = UIColor.greenColor()

        alertWindow.rootViewController?.presentViewController(self, animated: animated, completion: completion)
    }
}

private class whiteStatusBarVC: UIViewController {
    private override func preferredStatusBarStyle() -> UIStatusBarStyle {
        return .LightContent
    }
}
