applicationWillTerminate works as long as I don't switch off the iPhone

Question

to save some variables of my apps I use:

-(void)applicationWillTerminate:(UIApplication *)application {

NSUserDefaults *prefs = [NSUserDefaults standardU         


        

Answer 1

According to Apple's documentation

"NSUserDefaults caches the information to avoid having to open the user’s defaults database each time you need a default value."

If you want to make sure things are saved you should call "synchronize" on your prefs.
