quit app in iOS4

Question

I have an old app which did many UI initialization work in viewDidLoad of various views. In iOS4 home button just put the app in background so viewDidLoad won\'t get called

Answer 1

Try disabling backgrounding. Apple has this in their documentation

Answer 2

http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/Reference/Reference.html

you have to look up to the UIApplicationDidBecomeActiveNotification i think, but in the uiapplicationdelegate-protocol, there are even some other interesting things for you

or perfectly for you: UIApplicationWillEnterForegroundNotification as a new notification in ios4 for this problem

Answer 3

Try to check. UIApplicationExitsOnSuspend

Answer 4

There is a key in your app's Info.plist file called UIApplicationExitsOnSuspend, set it to the boolean YES, which will essentially revert the home button's functionality to pre-iOS4 and completely exit your app when the home button is tapped.
