this may sound silly, but is there a way to find palm down action on a iphone or ipad.
i am making a simple drawing app, and want to interpret a palm down on the screen action to put a palm imprint/image in the UIView.
so, i should be able to analyse if the touch event is a palm or not right ? how do i go about that ?
I suspect your best bet would be to use the UIGestureRecognizer after creating a custom gesture recognizer. (See the “Creating Custom Gesture Recognizers” section within Event Handling Guide for iOS.)
However, the problem will be the fact that you’re going to have a large area of contact that isn’t necessarily constant and pretty much all the standard code is designed to pick up discrete touches on the display.
