iOS8: Are apps on the multitasking screen in background?

I can see apps when I double tap the home button to open the multitasking screen. Does it means the apps are in background? I need to make sure if "(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions" method is not called when I tap an app on the multitasking screen.

I think that many apps remain on the multitasking screen. Some apps are launched at three month ago. I do not believe such apps are still remaining in memory.


No.

(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions" 

method does not call when app start again from the multitasking screen.


When you totally minimised the app, We can say that app is in background.

If App A is open. Now you are double tap on Home button. Other minimised apps will be display there. From that selection of app. Suppose you select App B ,

App A --> Background And App B --> Foreground

Thanks,
