What happens when the system purges an app while in background?
I know my app can be killed while in background by the system.
Is it also possible to have its data structures released but the app not being killed?
- I use to save user data in
-(void)applicationWillEnterForeground:. - I always restore that data in
-(BOOL)application:didFinishLaunchingWithOptions:
Should I also restore local data in -(void)applicationWillEnterForeground:?
If the app is killed it will come back through -(BOOL)application:didFinishLaunchingWithOptions: so my data will be restored, but if it is not killed but its data structures released it will came back through - (void)applicationWillEnterForeground: so no data will be restored.

If your app is killed and then relaunched your -application: didFinishLaunchingWithOptions: will be called.
If your app is backgrounded and then resumed -applicationWillEnterForeground: will be called.
You should not need to restore data state when -applicationWillEnterForeground: is called.
