iPhone为图像添加模糊效果 [英] iPhone adding blur effect to image

问题描述

我已经浏览过这个常见问题的堆栈，并且发现没有默认函数可以为UIImage添加模糊效果，并且为了使其成为必须操纵单个像素......我认为有很多尝试并完成此任务的高级用户。有没有人有这方面的代码，或者一些非常具体的指针应该如何做？

I have browsed stack for this so common issue, and have found that there is no default function to add blur effect to UIImage, and in order to make it one would have to manipulate individual pixels... I presume there are many advanced users who have tried and accomplished this. Does anyone have code to this, or some really specific pointers how this should be done?
