openURL is not working when App is in background in iOS

问题

I am trying to open one URL in Safari from my App when App is in background, below is my code

    [[UIApplication sharedApplication]openURL:[NSURL URLWithString:strURL]];

My App is hiting the above line during debugging, but not opening Safari with the given URL.

It's not possible, You cannot launch another app from the background state. If app in background then you can't have any event for handle your app event from iPhone/iPad screen. You must have to wake up your app. You can use local notifications.
