Hey all, I'm trying to figure out how to get a 2D touch interface overlay on an image. The image is of a Pan/Tilt grid that I want to overlay with a dot of some sort that shows the current value based on variables I have in the background. I have the image created and well adjusted within storyboard but I'm at a loss for how to create the touchable interface with that dot for feedback. Anyone done something similar to this?? Currently I have the values being adjustable with sliders and want to have the grid interface as well.
