How to dismiss alert view when application is put in background?

If I get an alert in my application and if I put application in background and press application icon to enter the application, a splash screen is displayed and then the alert pop up. Why splash screen appears? And if alert is not present and I put application in background and press application icon to enter the application, splash screen is not displayed.

If you want to dismiss all AlertViews programmatically you have to Remember a Reference to the currently shown Alterviews. I recommend a Singleton class where you ask for an AlertView and wich saves a Reference to the AlertView.

then you could use the 

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

in your AppDelegate and call a Function on the Singleton Class, wich itself calls 

[alert dismissWithClickedButtonIndex:0 animated:YES];

at all Alertviews.

The splash screen is as @akshay1188 mentions, is the Default.png in your project file. The reason for it being displayed, based on my best assumption, is because the OS has not managed to take a screenshot of your App before you go back to it. See this answer to a StackOverflow question where it was discussed.

As for the UIAlertView, @pKoul's anwser got my upvote.

The splash screen is actually the launch image that you might be using as Default.png

Maybe you can use the notification posted UIApplicationDidEnterBackgroundNotification in any class that needs some cleanup before entering bg. Do not forget to remove the observer in dealloc.

    [[NSNotificationCenter defaultCenter] addObserver: self
                                             selector: @selector(cleanup:) 
                                                 name: UIApplicationDidEnterBackgroundNotification 
                                               object: nil]

First you have to make the UIAlertView a property in your class. In your AppDelegate Class you can implement the applicationDidEnterBackground: Method in wich you can put something like this:

[yourViewController.yourAlert dismissWithClickedButtonIndex:0 animated:NO];

This should dismiss the alert if your app enters the background. Hope this helps!
