Nice transition from splash screen to main application screen using fade out and zoom in animation. Change the -application:didFinishLaunchingWithOptions: method of your application delegate class like this (assuming your splash image is named Default.png

gistfile1.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Put necessary initialization steps here...

    // Add imageView overlay with fade out and zoom in animation
    UIImageView *imageView = [[UIImageView alloc] initWithFrame:self.window.frame];
    imageView.image = [UIImage imageNamed:@"Default"]; // assuming your splash image is "Default.png" or "Default@2x.png"
    [self.window addSubview:imageView];
    [self.window bringSubviewToFront:imageView];
    [UIView transitionWithView:self.window
                      duration:0.75f
                       options:UIViewAnimationOptionTransitionNone
                    animations:^(void){
                        imageView.alpha = 0.0f;
                        imageView.frame = CGRectInset(imageView.frame, -100.0f, -100.0f);
                    }
                    completion:^(BOOL finished){
                        [imageView removeFromSuperview];
                    }];
    [imageView release];
    
    [self.window makeKeyAndVisible];
    return YES;
