iOS Hand Shadows

This code allows you to quickly and easily integrate hand shadows that follow your app's gestures in real time, allowing you to record more descriptive and intuitive demo videos.

What is this?

This code lets you add hand shadows over your UI during your gestures, which makes for immersive tutorial and demo videos.


Example image


Add a MMShadowHandView above all of your other views, and then call its methods with arrays of CGPoints wrapped in NSValues. Run the code for a demo of the shadows.

Building the Code

git clone
cd ios-hand-shadows
git submodule init
git submodule update

Open iOSHandShadows.xcworkspace in Xcode

The submodule depends on IOS-Universal-Framework and is built with the Real Framework option.

  1. Link against the built framework.
  2. Add "-ObjC++ -lstdc++" to the Other Linker Flags in the project's Settings
  3. #import <PerformanceBezier/PerformanceBezier.h>
