Hi! I'm porting a PocketPC game that makes use of the EDGELIB library to the iPhone (my first experience with a Mac platform). In PocketPC, the user can switch to another application and, when clicking again on its icon, the application restores itself automatically. Is there a similar thing on iPhone? Or should I write myself all the code that saves the application state before exiting?

Thanks in advance for your answers,

You have to write your state saving code yourself. There is a system in place to make that easy to do though, called NSUserDefaults.

[adding] Register for UIApplicationWillTerminateNotification so you can be notified when to save your state.

Or implement applicationWillTerminate: in your application delegate class.

Hi! Sorry for my late reply.

Since I'm using the EDGELIB library, I think that all those things you mention are wrapped under the library's framework. Nonetheless, I've found out that the method OnExit gets called whenever the user presses the Home button, so I've placed my call to the save function in there.

Thanks for all your help!
