I know I can call sync, but Apple recommends against it, and Say if it is necessary, I should only call it. So.
How could something go wrong?
Thank you.
The suggestion in the second article I linked to is to call synchronize in applicationDidEnterBackground:
Also remember, through the Xcode Stop to terminate your application usually does not save user defaults.
My [NSUserDefaults standardUserDefaults] is not saved. I close the application and restart it Everything will be restored. I don’t have my iOS device, so I’m not sure if this will happen on the device, but none of the other apps do it in the simulator, which leads me to believe that there is a problem with my code. I don’t Knowing what parts of the code I should include here, it simply added/modified the key in nsuserdefaults, and as I said it worked fine in the application, but after I restarted it it didn’t…

Your process may not be terminated properly, so NSUserDefaults has no chance to be stored. See also this, mainly this.
