I think yu didn't use the following functions 1.applicationWillResignActive & 2.applicationWillEnterForeground in your Application. so please use this following functions in AppDelegate.m - (void)applicationWillResignActive:(UIApplication *)application { } -(void)applicationWillEnterForeground:(UIApplication *)application{ }
