I want my app to quit when the user taps the home button, without going to the background. Is this possible?
Set the key UIApplicationExitsOnSuspend to true in your info.plist. See the docs.

Please tell me some solution for how to stop app at background when we close the app in iphone sdk 4.0 and above.
can any one provide me some sample code for it.
Thanks,

Set the UIApplicationExitsOnSuspend key in your app's Info.plist to YES.
This will make the app quit when you press the home button, instead of being backgrounded.
In the latest iOS, apps now "deactivate" rather than close by default. So the app retains state and stays in memory.
I want my app to reset its state when it's reactivated, just like when it's closed/opened on iPhone 3.
I suspect reactivate is the wrong word! But hopefully you know what I mean.
thanks
Add the UIApplicationExitsOnSuspend key to your Info.plist, and set it to YES. This will mark your application as NOT supporting multitasking, and it will quit just like it used to. Good luck!
You can opt out of multitasking by setting the UIApplicationExitsOnSuspend key in your project’s Info.plist and setting the value to YES.
This will make your app behave like it would on iOS 3.x.
There's a property list key for that. UIApplicationExitsOnSuspend is set in your Info.plist when you want to exit instead of suspend when the user hits the home button.
If you have an app that you developed pre-multitasking and you are having issues or you don’t need it, you can disable multitasking in the application’s Info.plist file.
Adding
Application does not run in background
or
UIApplicationExitsOnSuspend
will stop your application being suspended when it is closed.
In iOS 4, when a user presses the Home button, the running app will save the current state and go to background. However I'm developing an app and I don't want it to go to the background. I want it to kill itself, just like in iOS 3 and before. How can I do it? Thanks.
See "Opting Out of Background Execution" in the iOS Application Programming Guide:
"...you can explicitly opt out of the
background execution model by adding
the UIApplicationExitsOnSuspend key to
your application’s Info.plist file and
setting its value to YES."
I don't know if this is an iOS4 thing or something, but basically say I have a few screens in my app. Now, when I hit the home button and relaunch my app it launches the app on the screen where I left off. It's almost like it's not restarting my app, but resumes it. I don't want it to do that. (I'd like it to show my splash screen main menu, etc. )
Does anyone know how to resolve this? thanks
In iOS 4, apps are suspended (not terminated) when the home button is pressed. When you "relaunch" the app, it is simply moved to the foreground. If you want your app to terminate when the user presses the home button, set the value of UIApplicationExitsOnSuspend to YES in your app's Info.plist file. If you do this, when the user taps the home button the applicationWillTerminate: method of your app delegate will be called and then your application will terminate.
I think this should help you. Basically what you need to do is disable the multi-tasking features of iOS4.

That's exactly the multi-tasking you asked about yesterday working behind the scenes. You need to opt-out if you want that behavior. See answers to your previous question here. Have you read the answers there???
I loaded some app projects that I had been developing using the iPhone 3.1.3 Simulator. Now I got the 4.0 package, and for some reason when I hit the home button of the simulator to go the home screen and then go back to the app, it's in the same position as I left it. Is this now standard? What if I don't want it to do this? I'd rather have it restart every time.
What you're describing is fast App switching, which is new in iOS 4.
If you want your application to quit each time the user presses the Home button, add the UIApplicationExitsOnSuspend property key to your info.plist and set it to YES (check the box).
