I want to use blurring in my iOS app when it switch. Like PayPal and some other financial app where need to hide information. But I can't find any information or hint about this feature.
For example PayPal realization: http://40.media.tumblr.com/0334b065e28dfe2e325d32822d87246b/tumblr_mwcl35TZIt1qea4hso1_1280.jpg

If you don't want any of your Zoom information to be exposed while switching between multiple apps open on your iOS device, you can enable Blur snapshot on iOS app switcher. This setting blurs the Zoom app preview screen in the iOS task switcher when multiple apps are open.
You will need to create the blur effect using the UIBlurEffect Class in the viewDidLoad method. After that you'll need to apply the effect to the UIVisualEffectView. The UIVisualEffectView needs to have the container dimensions defined, and it will be the first view of the stack of the view controller.
You need to add the following code to your applicationWillResignActive function
let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.Dark)
let blurEffectView = UIVisualEffectView(effect: blurEffect)
blurEffectView.frame = window!.frame
blurEffectView.tag = 221122
self.window?.addSubview(blurEffectView)
Then in your applicationDidBecomeActive, use the line
self.window?.viewWithTag(221122)?.removeFromSuperview()
