As suggested by Apple I have provided a launch image which equals to my home page iOS app.
At the moment I am testing on the iPhone simulator and I wanted to know if the same happens on real devices.
Everything works fine, however when I am in pages other than home page and I exit from application by pressing the button, then when I enter again, the launch images shows for an instant, and then suddenly the last viewed pages appears.
I wonder how can I avoid this "flickering" of pages. I don't know if this is important, but I am using Storyboards.
This is the intended behaviour if you immediately start the app again. See my answer to another Stack Overflow question on a similar matter.
To explain, the Default.png image is used when the OS is unable to take a screen shot of your last view state. Giving the OS a little longer to screen shot the app will prevent the Default.png being used. This is done so that the device does not just show a black screen, followed by your app popping in.
I am not aware of functionality to see if the OS has finished taking a screen shot. If this was possible you could place a UIImageView on top of your last view and do a more subtle fade out one you have control again.

About a week ago xcode showed me some error and when I clicked to solve the problem, xcode added this picture:
My questions are: What is it good for? Why do I need it?
Thank you.
Yes you must include one.
From Apple's Interface Guidelines
To enhance the user’s experience at app launch, you must provide at least one launch image. A launch image looks very similar to the first screen your app displays. iOS displays this image instantly when the user starts your app and until the app is fully ready to use. As soon as your app is ready for use, your app displays its first screen, replacing the launch placeholder image.
Without this default image (or a LaunchScreen storyboard), your app would not take all the available screen space on iPhones with 4" displays (iPhone 5, 5s, SE). This is the default image that those iPhones would use.
Of course you can (should!) change it with the one you designed.
Runtime, leading to the top and bottom of applications were empty out a lot , because the application is based on a 320x480 size to run.
I have my problem still unsolved Splash screen is landscape although the whole game is in the portrait mode. SpriteBuilder + cocos2d , so I see only one way.
How to remove splash screen at all, so that game loads at once ?
This is not possible. An image named Default.png (or under a similar name, depending on the device and what the app supplied) is always loaded when an app launches.
This is done by iOS specifically because no app can technically launch instantly (as in: within a tenth of a second or two).
I know the question is old, but I had the same problem and I solved it specifying none in "Launch screen file" (under General settings).
I am working on winRT XAML application, in my main page i have some large images. When i launch the aplication it shows blank screen for a while in between splash screen and main screen. Any solution for this? i think same issue as in Phonegap showing white screen after the splash screen - IOS but its in winRT in my case.
This sounds like something I experienced in the past when I set the page background to an image. It can take a little while for the image to get loaded and displayed on the page, and therefore you end up with a fraction of a second of unstyled page. Is that what's going on here? If so, try reducing the size / quality of your image to see if it makes a difference. If it does, your work is just starting as you try to find an acceptable compromise between image quality and file size.
Look up "extended splash screen". The technique is basically that you make your app display a splash screen image on a solid color background that looks the same as the one displayed by the Windows shell when it starts your app. The splash screen image is small enough that when your app starts showing just the splash screen - it shows seamlessly and then you can load your first page in the background.
i am migrating my iOS app onto mac. the loading time is a bit long (around 5 seconds) thus i need a splash loading screen (Just like Default.png image for iOS) but the project made from cocos2d template just shows a white screen. not sure about other apps. so is there anyway to set it?
I know that the screen size is not fixed on a mac app. but i have set a default size. and use auto scale in case of full screen mode.
EDIT:
I have tried a light weight loading scene as well but failed since the MainScene itself is light weight as well. I think the major loading time is due to the cocos2d environment set up.
In OS X a window appears when the application launches, it's not designed to use splash screens.You might want to reconsider that choice.
But if the window is still to slow to load or to display its contents, you can still do that but manually, it isn't easy like in iOS.You need to display another view inside the window until it loads.
EDIT
A little more of context: for example you can set in your xib file an image view containing the image do display.
Then you make start another thread that loads all the content that you need.After this, run a selector on the main thread that updates the window.
Based on my tests in Cocos2d 1.0.1 & 2.0 the basic Cocos2d OS X app launches really quickly.
This makes it seem pretty likely that it's something about your first scene that is taking a long time to load, or something else. Instruments can help you gather information about what your app is doing.
I suggest you make an initial lightweight cocos2d scene that will load quickly at startup and then load your second scene and transition to it. Ideally the loading of the assets for your second scene would be asynchronous (at least the ones that are slow). There are numerous blog posts on how to do this. (search for "cocos2d asynchronous loading" and you'll find many, such as this one: How to preload your game assets in a loading scene, though something more recent might be preferable).
I want to know that how one should proceed in building animated splash screen.
I already did the animated splash screen with images but here I want to add custom animation like something is drawn on screen etc.
can anyone guide me through this.
simply you need to present a UIViewController which is hold your animations and dismiss it when your app is ready to launch. but also I think its better to follow apple HIG .. as apple describe you should
Supply a launch image to improve user experience.
Avoid using your launch image as an opportunity to provide:
An “application entry experience,” such as a splash screen An About
window Branding elements, unless they are a static part of your
application’s first screen Because users are likely to switch among
applications frequently, you should make every effort to cut launch
time to a minimum, and you should design a launch image that downplays
the experience rather than drawing attention to it.
Generally, design a launch image that is identical to the first screen
of the application.
Exceptions:
Text. The launch image is static, so any text you display in it will
not be localized.
UI elements that might change. Avoid including elements that might
look different when the application finishes launching, so that users
don’t experience a flash between the launch image and the first
application screen.
