Issue TIMOB-19667: iOS9.1: Support for Apple Pencil
https://developer.apple.com/library/prerelease/ios/documentation/UIKit/Reference/UITouch_Class/index.html#//apple_ref/occ/cl/UITouch iOS 9.1 introduces APIs that help you use coalesced and predictive touches that can be produced by Apple Pencil on supported devices. Specifically, the UITouch class includes: The preciseLocationInView: and precisePreviousLocationInView: methods, which give you the precise location for a touch (when available) The altitudeAngle property and the azimuthAngleInView: and azimuthUnitVectorInView: methods, which help you determine the altitude and azimuth of the stylus The estimatedProperties and updatedProperties properties, which help you prepare to update touches that are estimated For an example of some ways to take advantage of these APIs in your app, see the sample project [TouchCanvas: Using UITouch efficiently and effectively|https://developer.apple.com/library/prerelease/ios/samplecode/TouchCanvas/Introduction/Intro.html#//apple_ref/doc/uid/TP40016561].
