推荐答案

自从 iOS 7 发布以来，这个问题一直受到很多点击，我想我应该跟进我最终做了什么.

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.

当时我个人用 photoshop 模糊了图片，但是有很多很棒的第三方库可以做动态和静态em> 模糊，这里有几个:

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 中提取了一层，并应用于获得 iOS 7 原生模糊的任何视图:https://github.com/JagCesar/iOS-blur/
• 这个库是一个实时模糊库，可以实时模糊任何视图在它下面:https://github.com/alexdrone/ios-realtimeblur(正如所指出的by qegal)
• 另一个具有相同实时模糊效果的图像:https://github.com/nicklockwood/FXBlurView
• 这个图书馆是我个人使用的图书馆，它很棒，允许您可以在其他设置中设置色调颜色:https://github.com/ivoleko/ILTranslucentView

• 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

我想发布这个是因为您不再需要截取单个帧或屏幕的屏幕截图.

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，Apple 包含了一个内置的模糊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)
