How is it possible to create a blur view on the first view controller in an iOS app? Like Xcode's blur view in the navigator blurring the desktop's background, I've recently recognized that Apple's 'Remote' App does the same on iOS (the background of the app is the blurred background image). Is this possible to achieve in any way using public API? Replacing the UIView by a UIBlurView only gives a gray background...
Nobody who’s commented or answered here seems to realise that you want to blur the user’s own wallpaper and use that as the background for your root view controller, like what is achieved in Apple’s own apps (such as Remote).
While it may have been possible in earlier versions of iOS, it is currently not possible to achieve this effect in your own app using public APIs.
