如何在UITableViewCell的背景中实现实时iOS7模糊效果 [英] How to implement a real time iOS7 blur effect in the UITableViewCell's background

问题描述

我希望UITableViewCell的背景具有iOS7模糊效果。它是动态的，意味着，当单元格滚动时，它的模糊背景应该根据下面的颜色而改变。

I want the UITableViewCell's background to have an iOS7 blur effect. It's dynamic, means, while the cell is scrolling, its blurred background should change depend on the color below.

我发现了一些相关主题。

I found some relative topics.

iPhone SDK - 磨砂玻璃（iOS 7模糊）效果。它介绍了GPUImage。它关于静止图像，我没有弄清楚如何制作动态图像。

iPhone SDK - Frosted Glass (iOS 7 Blur) Effect. It introduce GPUImage. It about still image, I didn't figure out how to make a dynamic one.

iOS 7动态模糊效果，如控制中心。它使用UIToolbar作为单元格的背景，利用系统内置的模糊效果。它工作得很好，但只是透明度有点低。我已经调整了工具栏的alpha值，但它并不理想。

iOS 7 dynamic blur effect like in Control Center. It use UIToolbar as the background of cell, taking advantage of system built-in blur effect. It works great, but just the transparency is a little low. I have adjusted the alpha of tool bar, but it doesn't ideal.
