You can't get the exact position of a touch on the remotes touch surface, how ever you can get the top, bottom, left and right. Think of the current Apple remote it has an up, down, left and right buttons. You can detect touches in the same way.
The below will be triggered when a touch event occurs on the remotes touch surface.
- (void)pressesBegan:(NSSet<UIPress *> *)presses withEvent:(UIPressesEvent *)event
{
for (UIPress *item in presses)
{
NSLog(@"item = %@", item);
}
}

A UIPress has a few properties on it. The "UIPressType" of a UIPress will tell you which button was pressed on the remote. See below for the types of button presses on the new Apple Remote.
