title: How can an iOS app know if a keyboard is already on the screen when the app opens (iOS Multitasking)
body: <p>How can an iOS app know if a keyboard is already on the screen when the app opens? Once an app is running, it can receive keyboard show/hide notifications. But if the app opens as a secondary app in Split Screen mode while the primary app already has a keyboard showing, the secondary app does not receive any notifications to tell it to adjust its views for the keyboard. And as far as I can tell, these notifications are the only way to tell if a keyboard is showing and what its frame is, to then obtain the necessary layout constraints. Is there a way to get this information, or should a bug report be filed for this issue?</p>
