iOS 7 Blur with Xamarin.iOS


Make Your App Look Cool

Recently I watched a video from WWDC 2013, where the presenters showed how to create a background image for a button that blurs the image underneath. This takes advantage of a new method in iOS 7 - DrawViewHierarchy(). This method lets you get an UIImage of your background, and blurring it is done with some extension methods. These methods were provided as a category (similar to C# extension methods) called ImageEffects.h and ImageEffects.m.

The Binding

I have bound the categories here. Download the project and build the .dll. You can then include the ImageEffects.dll and you will have the extension methods for blurring on your UIViews.
