I used “Add to Home Screen” to put a link to my app on my iPad. If I use the link, it starts up the app fine; if I switch to something else, and then hit the link again, it starts up a second (or third, etc.) instance of my app on top of the previous instance.
If I use the X in the upper left corner to close the latest instance, the older instance is underneath, still working.
How can I tell whether or not my app is already running, and not open a new instance but rather just let the existing instance display?
I’ve looked at the list from
globals() and don’t see anything obvious there.
