title: How to put UIWindow above keyboard in iOS9?
body: <p>I have a custom alert that I made using <code>UIWindow</code> which is supposed to appear above the keyboard. In iOS8 and below, this worked fine, however in iOS9 the alert window goes beneath the keyboard. Is this a bug or the intended behavior? Are there any work arounds or changes that can be made to have the <code>UIWindow</code> go above the keyboard?</p>
