Some users of my app complain that it stops responding to touch after a while. The screen is still updating, and the app seems to be working normally otherwise. It just doesn't respond to any touches anymore.
It is not a problem with the touchscreen itself, because the user is able to swipe up to get to the home screen, and then interact with other apps as normal. When re-opening my app, it is still unresponsive to touch.
The only way to solve it, is to restart the app.
Does anybody have a similar experience, and knows what could cause it?
The app is based on UIKit, and still written in Objective-C, if it matters. The iOS version involved does not seem to matter, it happened with a couple of them.
