Line drawn on iPhone not where finger is

[yusuftor]

I have a UIJotView that covers the screen and nothing else. When I move the mouse on the simulator it draws perfectly. When I move my finger on my iPhone the line is always drawn about 20ish pixels to the top right of where my finger is. The distance away from my finger changes as I move across the device. Why is that?

When I see this, it's usually because the JotView has been resized with constraints or auto-layout to a different size that it was initialized with. Once the view has been created, it needs to keep its same size forever. if you need to get a different sized then you need to make a new JotUI view.
