so - Do background applications *ever* quit in iOS 4?

"Apps on iOS4 will quit if they're not compiled against the 4.0 SDK (therefore
not being multitasking aware) or if the UIApplicationExitsOnSuspend key is
specified and set to true in the app's info.plist file."

bignerdranch.com - applicationWillTerminate vs. applicationDidEnter-
Background

"So I copied the code that was in applicationWillTerminate and and put it in
applicationDidEnterBackground.

My question then - is it the proper thing to do to have the same code in both
applicationWillTerminate and applicationDidEnterBackground? "

so - Default.png problem with iPhone OS 4?

"What should Default.png contain? Currently it seems that iPhone OS
makes snapshots of the screen before closing the app, and next time
it launches with that exact snapshot as “splash screen image”."

iphonedevsdk.com - Keep NSTimer running when app is in background

"I am having same problem and I've managed to setup UILocalNotification
and it works fine. But, I get event fired once timer gets to zero (i.e., when
current clock is equal to setup) instead of getting event, for instance, every
second."

so - What method is called when application appears from back-
ground on iPhone?

"Along with the applicationDidBecomeActive: and applicationWillEnterFore-
ground: messages sent to the application delegate, the OS will also send
corresponding UIApplicationDidBecomeActiveNotification and UIApplication-
WillEnterForegroundNotification notifications."

so - iPhone 4 App continues to run in background with debugger

"Hi, on iphone with multitasking and iOS4.1, if i have the debugger con-
nected I noticed that code is still being run in the background, my break-
points are still hit, timers are running. This without any of the background
modes set."

[delovski]

so - (void)applicationDidEnterBackground:(UIApplication *)application

"There is also the UIApplicationDidEnterBackgroundNotification notification
that you can listen for instead of doing the above."
