iphone - iOS 7: Is it possible to make UIView's background transparent to show the blurred background?

Question

I ask this question after seeing apps like Reminders or Safari's tab view using this.

As you can see there is a translucency between the app and the home screen. Is there anyway to achieve this in iOS 7? Is it a private api?

Answer 1

可悲的是没有这样的运气 - 它是一个私有 API。
