如何在iOS 7中将用户背景添加到具有模糊效果的应用程序中？
[英]How do I add a user background into the app with a blur effect in iOS 7?
问题描述
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. 
基本上，我想知道是否可以添加类似于在没有杂志的情况下打开报亭的效果，并且遇到一种效果，您可以在其中看到带有模糊效果的用户墙纸。 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. 我设法设法通过一些.plist设置更改将墙纸放置到应用程序上，但想知道是否有更好的方法还可以增加模糊效果。

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. 您可以使用Apple在其示例代码中提供的UIImage类别， UIImage类别使您可以模糊具有各种样式和颜色的UIImage 。

Search the page for UIImageEffects , download it. 在页面上搜索UIImageEffects ，然后下载。 Open the project, and you'll find a UIImage category you can move to your project. 打开项目，您会找到一个UIImage类别，可以将其移至您的项目。
