Remarks

Since iOS 9.0, TouchesMoved(NSSet, UIEvent) events are raised on supported hardware and configurations for changes in user-applied pressure. The Force property of the UITouch object in the touches set argument contains the magnitude of the touch that raised the event. The following example shows a basic use:

if (TraitCollection.ForceTouchCapability == UIForceTouchCapability.Available) {
      UITouch t = touches.AnyObject as UITouch;
      ForceLabel.Text = "Force: " + t.Force.ToString ();
}
else {
      ForceLabel.Text = "Force Not Active";
}
