UIAlertController - showing blank titles in the alert
<p>One of our app had alerts and we used to use the UIAlertView. We have updated from UIAlertView to UIAlertController (available from iOS8) since UIAlertView was deprecated in iOS9. Recently we received an issue from one of our customers saying that the alert buttons are showing blank sometimes but the buttons are functioning as expected in any case whether the title shows or not.</p>

<p>Device: iPad mini (1st generation)
OS version: iOS9</p>

<p>So, what could be the issue of showing blank sometimes for Alert buttons?</p>
