I’m storing certain values in NSUserDefaults, but after several sessions, I find nil values for those variables whenever I’m retrieving them. It’s nowhere that I’m resetting them in my whole program. How can this happen?
Thanx in advance.
If you register default defaults and set them to nil, in principle an interrupted or mismanaged write to defaults will cause a reversion to the nil default default the next time the app loads. I have never seen that happen, however. Crashes can also corrupt the defaults.
It is more likely that you are simply accidentally setting them to nil somewhere.
