如何将模糊应用于UIView？ [英] How to apply blur to a UIView?

问题描述

现在我正在构建一个需要模糊整个UIView的iPhone应用程序。我怎样才能做到这一点？我见过这个框架，但我认为这不适用于UIView。是否有另一种模糊UIView的方法？

推荐答案

自从iOS 7发布以来，这个问题已经得到了很多点击，我想我应该跟进我最终做的事情。

Ever since the release of iOS 7, This question has been getting a lot of hits and I thought I should follow up on what I ended up doing.

我个人用photoshop模糊了这张照片，但是有很多很棒的第三方库可以用来做 动态 和 静态 模糊，以下是一对：

I personally blurred the picture at the time with photoshop, but there are many great third party libraries available that do dynamic and static blurring, here are a couple:

• 这个巧妙的库从 UITabBar 中获取一个图层并应用于
  任何视图以获得iOS 7的原生模糊：

• 这个库是一个实时模糊库，它可以模糊它下面的任何视图

• 另一个执行相同实时模糊的工作：
  https://github.com/ nicklockwood / FXBlurView


• 此库是我个人使用的库， Great ，允许
  你在其他设置中设置色调颜色：

• This ingenious library takes a layer from UITabBar and applies to any view to get iOS 7's native blur: https://github.com/JagCesar/iOS-blur/
• This library is a real time blurring library that live blurs any view below it: https://github.com/alexdrone/ios-realtimeblur (as pointed out by qegal)
• Another one that does the same realtime blur: https://github.com/nicklockwood/FXBlurView
• This Library is the one I personally use and is Great, allowing you to set the tint color among other settings: https://github.com/ivoleko/ILTranslucentView

我想发布这个，因为你不再需要来截取各个帧或屏幕的截图。

I wanted to post this because you no longer need to take screenshots of individual frames or screen.

iOS 8：随着即将发布的iOS 8版本，Apple已经内置了模糊的 UIView ， UIVisualEffectView （ https://developer.apple.com/documentation/uikit/uivisualeffectview ）

iOS 8: With the coming release of iOS 8, Apple has included a built in blurred UIView, UIVisualEffectView (https://developer.apple.com/documentation/uikit/uivisualeffectview)
