How can I display a splash screen for longer on an iPhone?

Question

Read the Apple iPhone Human Interface Guidelines (HIG). The "splash screen" isn't supposed to be for branding or displaying a logo, it's supposed to look like the default condition of the app so it appears to start up quickly.

Making it stay there for longer would be a violation of the HIG.

The simplest way to do this is to create a UIImageView who's image is your Default.png. In your applicationDidFinishLaunching: method, add that image view to your window, and hide it when you'd like your splash screen to go away.

I needed to do this to block showing a table view until the data was loaded over the network. I used a variation of one I found here:

In the interface of your App Delegate:

@interface AppDelegate : NSObject 
{
  UIImageView *splashView;
}

In the implementation:

@implementation AppDelegate
- (void)applicationDidFinishLaunching:(UIApplication *)application {


  // After this line: [window addSubview:tabBarController.view];

  splashView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
  splashView.image = [UIImage imageNamed:@"Default.png"];
  [window addSubview:splashView];
  [window bringSubviewToFront:splashView];

  // Do your time consuming setup

  [splashView removeFromSuperview];
  [splashView release];
}

Make sure you have a Default.png in the resources

in your appDelegate , theres a method called applicationDidFinishedLaunching use a sleep function. Pass a digit in the sleep function for the no. of seconds you want to hold screen.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{    
    [window makeKeyAndVisible];
    [window addSubview:viewController.view];
    sleep(5);
    return YES;
}

I searched so much for this thing and everybody gave their own complex point of view. I couldn't find a simple way that would just let me do it.

KISS ( Keep it simple and Smart :) I avoided the actual as its offensive.
