MDBlurView Demo

Important!

As of recently, Apple has been rejecting apps that use MDBlurView. To work around this, place the following set of defines at the bottom of your *Project*-Prefix.pch file, so that MDBlurView can no longer be found via static analysis:

#ifndef DEBUG

#define MDBlurView CheeseSandwichView
#define MDBlurLuminosity CheeseSandwichLuminosity
#define MDBlurLuminosityAutomatic CheeseSandwichLuminosityAutomatic
#define MDBlurLuminosityBright CheeseSandwichLuminosityBright
#define MDBlurLuminosityDark CheeseSandwichLuminosityDark

#define blurFraction cheeseSandwichFraction
#define blurRadius cheeseSandwichRadius
#define blurLuminosity cheeseSandwichLuminosity
#define _blurFraction _cheeseSandwichFraction
#define _blurRadius _cheeseSandwichRadius
#define _blurLuminosity _cheeseSandwichLuminosity
#define setBlurFraction setCheeseSandwichFraction
#define setBlurRadius setCheeseSandwichRadius
#define setBlurLuminosity setCheeseSandwichLuminosity

#endif

Do not forget to rename the occurances of cheeseSandwich in the above sample code to a new string of your choosing, otherwise Apple will end up blocking CheeseSandwichViews as well 😉.

Note that you can continue referencing MDBlurView in your code — the only difference will be that when it is compiled, it'll be replaced which whatever you renamed it with in the above defines.

Purpose

MDBlurView is a multiuse background view you can use for bluring in your iOS 7 Apps. In addition, it provides some customizable properties that all adhere to UIAppearance, including some novel ones such as masking. Please visit the MDBlurView repository for the actual code :)

If you use MDBlurView in your app, please add it to the list!

Installation

$ git clone https://github.com/mochidev/MDBlurViewDemo --recursive

To include it into your own projects either download the source, or run the following on your git repo:

$ cd <your_repo>
$ git submodule add git@github.com:mochidev/MDBlurView.git <local_subpath>/MDBlurView

This will allow you to update it at anytime by running $ git submodule update.

Usage

Simply add the MDBlurView submodule to your project, and add an MDBlurView to your view, either in Interface Builder, or in code:

MDBlurView *blurView = [[MDBlurView alloc] initWithRect:CGRectMake(0, 0, 100, 100)];

Notes

In the background, [MDBlurView](https://github.com/mochidev/MDBlurView) uses _UIBackdropView to generate the blur, generated by using a UINavigationBar, and gutting its internals. For this reason, Blurs are not available pre-iOS 7 (because the lack of UIBackdropViews), nor are they available on devices where Blur is disabled (like the iPhone 4).

Internally, it seems that _UIBackdropView uses three CAFilters on its layer to acheive the effect.
