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.
You shouldn't need to configure anything, but if you want to tweak some knobs:
touchImage: pass aUIImageto use for showing touchestouchAlpha: change the visible-touch alpha transparencyfadeDuration: change how long lifted touches fade outstrokeColor: change defaulttouchImagestroke color (defaults to black)fillColor: change defaulttouchImagefill 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.
