I can’t seem to find this in the forums. I guess all my keyword searches are dancing around what the topics must have been labeled.
Basically, I don’t want my game to reset when I return to the iPhone main screen or switch to another app in multitasking. I tried using Application.runInBackground but it didn’t have any effect.
It should not reset if you are using Unity 3 on a device running iOS 4.
run in background has no impact on the iOS as applications never run in background, thats just technically not possible on the iOS
I should elaborate. It starts off with the introduction scene. Just a logo and then it loads the main menu. No matter what scene you leave from, it will always load the intro scene again.
Moonjump, I’m on Unity 1.7 IOS Pro.
Thanks dreamora for clearing that up!
Did you leave the application and go straight back in (to ensure its not killed out by iOS due to lack of available ram) and did you ensure to be on a 3GS+ device so you have background tasks at all? 
3G / itouch 2nd gen don’t have it.
It is technically possible on iOS, you’re allowed to specify either more time to run, or run it in the background. For example skype style apps.
Its on a brand new iPhone 4. I switched back as soon as I could.
Quick reply (haven’t completely read the thread!)
Did you set the ‘Target iOS Version’ to 3.2? Don’t leave it to 3.0

1.7 is from before multitasking, so didn’t have it when I switched over to 3. As far as I am aware it was never updated after I changed. Some user may have come up with a solution which may have been posted on these forums.
Whether multitasking works or not depends on how the project is built in XCode (specifically the base SDK, which should be the latest version), not Unity.

Ya, its targeted for 3.2.
I think its something with the Xcode. Any ideas?
switched back means you opened the task bar and went in that way, right?
and the entry in the plist wasn’t added that tells xcode to terminate the application
What I do is I have the application open, I then either press the iPhone home button to escape or double tap it to switch to some other application. When I return to my Unity app, it starts from the beginning as if I’ve never used it.
I booted up the Penolpe demo and the same problem is happening. It’s not just occurring with my game. Some setting must be off.
