Sorry for what is likely a dumb question, but I'd appreciate any help I can get:
To start: my wife asked me to build a simple "behavior tracker" for the kids, which seemed like a good first project for me. System is simple: kids start out green, and based on user input they can move through yellow to red (and back) based on their behavior throughout the day. Ultimately, I'd like to have an archive/calendar view that we can look back at to show the kids how they ended each day, but right now am just trying to get the basic functionality working.
I've got a view built in the UI builder that has a couple different subviews built in to it. I've been able to successfully capture the appropriate touch events that enables me to touch each subview's area, and with swipes either way it adjusts the color, somewhat similar to a slider, but based on the x coordinate of the touch event.
I'd like to have an oval (or maybe even an image at some point, so the kids can choose an icon or little avatar) drawn in the subview when the user lifts their finger, so the last position has a visual mark to identify the last set position (in addition to the color, which already works), but I can't for the life of me get one to draw. Can anyone help me out with this?
Much appreciate it!
