How do I add a user background into the app with a blur effect in iOS 7?

Question

Basically I want to know if it's possible to add an effect similar to when you open Newsstand with no magazines and you encounter an effect where you can kind of see the user wallpaper with a blur effect added onto it. I sort of managed to get the wallpaper onto the app with a few .plist settings changes, but want to know if theres a better way that also adds the blur effect.

regards, Patricio

You can use the UIImage category that Apple provides in its sample code, that allows you to blur a UIImage with a variety of styles and colours.

Search the page for UIImageEffects , download it. Open the project, and you'll find a UIImage category you can move to your project.
