Fingertips

Presentation mode for your iOS app

Fingertips is a small library (one class) meant for presentations from iOS devices that shows all touches and gestures so that the audience can see them.

This is only designed for the iPad 2 and iPhone 4S (or later), which feature hardware video mirroring support. This library does not do the mirroring for you!

Just drop in our replacement UIWindow subclass and your app will automatically determine when an external screen is available. It will show every touch on-screen with a nice partially-transparent graphic that automatically fades out when the touch ends.

Fingertips requires iOS 5.0 or greater and ARC. It uses no private API and is safe for App Store submissions.

Configuration

You shouldn't need to configure anything, but if you want to tweak some knobs:

  • touchImage: pass a UIImage to use for showing touches
  • touchAlpha: change the visible-touch alpha transparency
  • fadeDuration: change how long lifted touches fade out
  • strokeColor: change default touchImage stroke color (defaults to black)
  • fillColor: change default touchImage fill color (defaults to white)

If you ever need to debug Fingertips, just set the DEBUG_FINGERTIP_WINDOW environment variable to YES in Xcode or set the runtime property alwaysShowTouches to YES.
