Show splash screen each time app becomes active

Question

I want the splash screen to be displayed each time app becomes active. I have created a function showSplash which I call in applicationDidBecomeActive:

-(void)showSplash
{
    UIImageView *splashScreen = [[UIImageView alloc] initWithImage:[UIImage imageNamed: @"Default.png"]];
    [self.window.rootViewController.view addSubview: splashScreen];
    [self.window makeKeyAndVisible];
    NSLog(@"begin splash");
    [UIView animateWithDuration: 4.2
                          delay: 0.5
                        options: UIViewAnimationOptionCurveEaseOut
                     animations: ^{  
                         splashScreen.alpha = 0.0;
                     }
                     completion: ^ (BOOL finished) {
                         [splashScreen removeFromSuperview];
                         NSLog(@"end splash");
                     }
     ];
}  

This is how I call this function :

- (void)applicationDidBecomeActive:(UIApplication *)application {
[self showSplash];
}

But no splash screen appears. Please correct me.

If you want the application to have a fresh start every time you get back to it, you could also disable background execution, as stated in the Apple Documentation (last section titled "Opting Out of Background Execution"):

If you do not want your app to run in the background at all, you can explicitly opt out of background by adding the UIApplicationExitsOnSuspend key (with the value YES) to your app’s Info.plist file.
