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
- (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
