Question

I am looking for some reference about the animation such that when you click on the application, it will bring you the first screen but slowly.

Does anybody know what it is please advice me on this issue. Thanks

edit
I just wanna make a nice transition after all.Whenever I click on the application, the first screen just come up. I would like to make it nicer just like the first screen is brought slowly slowly and displayed on the scree. Hope it makes sense now.

I assume you mean fading out the splash screen after the application starts? You can add something like this to applicationDidFinishLaunching to display the splash art full-screen immediately on boot, and then fade it out

UIView *topView = self.window.rootViewController.view;
bootSplashView = [[UIImageView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
bootSplashView.image = [UIImage imageNamed:@"iPhoneDefault.png"];
[topView addSubview:bootSplashView];
[self performSelector:@selector(fadeBootScreen) withObject:nil afterDelay:0];

And then in a separate method:

- (void)fadeBootScreen
{
    [UIView animateWithDuration:0.4 delay:0.0 options:UIViewAnimationCurveEaseIn animations:^{
        bootSplashView.alpha = 0.0;
    } completion:^(BOOL finished) {
        [bootSplashView removeFromSuperview];
        bootSplashView = nil;
    }];
}

Make sure to add ‘bootSplashView’ as an class variable. If your app can start in different orientation (relevant on the iPad), specialize for those cases by loading a different image.
