iOS: Fade from the splash screen to your initial view. Works on iPhone 5 (and 4,3). Add a UIImageView property called splashView.

FadeSplash.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
   //.. do other setup

    CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height;
    
    // Transition neatly from splash screen
    
    // Very odd, on iPhone 5 you need to position the splash screen differently..
    UIImage* myImage;
    if ([UIScreen mainScreen].scale == 2.f && screenHeight == 568.0f) {
        myImage = [UIImage imageNamed:@"Default-568h@2x.png"];
     	self.splashView = [[UIImageView alloc] initWithFrame:CGRectMake(0,20, 320, screenHeight-20)];
    } else {
        myImage = [UIImage imageNamed:@"Default.png"];
      	self.splashView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0, 320, screenHeight)];
    }
    
    self.splashView.image = myImage;
	
    [self.window addSubview:self.splashView];
    [self.window bringSubviewToFront:self.splashView];
	
	// setup the animation of the splash screen
	[UIView beginAnimations:nil context:nil];
	[UIView setAnimationDuration:1.0];
	[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.window cache:YES];
	[UIView setAnimationDelegate:self];
	[UIView setAnimationDidStopSelector:@selector(startupAnimationDone:finished:context:)];
	self.splashView.alpha = 0.0;
	[UIView commitAnimations];
}

// Called when the animation that hides Default.png finishes, use it to clean up.
- (void)startupAnimationDone:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {
	[self.splashView removeFromSuperview];
}

I have this in my App Delegate and - (void)startupAnimationDone:finished:context: is called, but the duration makes no difference. I don't see a delayed fade.

Don't work for me as well
