and to think there was an api to derive pressure from contact size back in 2.0<p><a href="https:&#x2F;&#x2F;developer.apple.com&#x2F;library&#x2F;ios&#x2F;documentation&#x2F;UIKit&#x2F;Reference&#x2F;UITouch_Class&#x2F;index.html" rel="nofollow">https:&#x2F;&#x2F;developer.apple.com&#x2F;library&#x2F;ios&#x2F;documentation&#x2F;UIKit&#x2F;...</a><p>anyone knows any app usage of this? I remember some games had pressure calculated from the accelerometer, don&#x27;t know if any did use this one instead.
