iPhone: Splash screen in app - Good or Bad?

I'm going to submit a Lifestyle app to the App Store. I'm confused whether to add a Splash Screen to the App or not ?

Please advis开发者_JAVA百科e me whether it's a good or bad idea as far as usability and App Store's submission guidelines are concerned.

Its bad - you shouldn't do that! Please read the Start Instantly Section of the Apple HI Guidelines

Avoid displaying an About window or a splash screen. In general, try to avoid providing any type of startup experience that prevents people from using your application immediately.

You should definitely at least add a Default.png to your app if I understand your question correctly.

Launching an app and looking at a black screen for a split second is not the best user experience. Some nice-looking image with your company name or app logo will do. Or you could follow Apple's guidelines and present an image of the starting user interface so that your app will seem to load instantly.

Here's a relevant doc.

The developers guides mostly suggest a splash that looks like the starting screen of your app, to give people the impression the app has started. This has the bonus of allowing the user to start figuring out what they want to do while the program finishes loading.

From a users standpoint, I dislike most splash screens, I just want to get to the program, not look once again at what constitutes an advertisement for the program.

if your app loads blazingly fast,then you can provide this method in

- (void)applicationDidFinishLaunching:(UIApplication *)application 

[NSThread sleepForTimeInterval:3];

Before your view controller is loaded.

It will halt the main thread for 3 seconds,which will give time to your splash screen.Thats the way i do and there is no problem with this method,as you are working on the main thread.

Yes, you can add a splash screen to your app.

Depending on what you do with your splash screen as far as extravagant animations go, I would go subtle, with minimal animations.

You can add a Default.png (see iOS documentation!) to your application bundle. This image is being shown full screen while your application is loading.

Other than that, I wouldn't add a splash screen to your app.
