I am developing an application using the iOS SDK. I need to know what Default splash screen sizes I need.
2018 Update - Please don't use this info !
I'm leaving the below post for reference purposes.
Please read Apple's documentation Human Interface Guidelines - Launch Screens for details on launch screens and recommendations.
Thanks

July 2012 - As this reply is rather old, but stills seems popular. I've written a blog post based on Apple's doco and placed it on my blog. I hope you guys find it useful.
Yes. In iPhone/iPad development the Default.png file is displayed by the device automatically so you don't have to program it which is really useful. I don't have it with me, but you need different PNGs for the iPad with specific names. I googled iPad default png and got this info from the phunkwerks site:
iPad Launch Image Orientations
To deal with various orientation options, a new naming convention has been created for iPad launch images. The screen size of the iPad is 768×1024, notice in the dimensions that follow the height takes into account a 20 pixel status bar.
Filename Dimensions
Default-Portrait.png * — 768w x 1024h
Default-PortraitUpsideDown.png — 768w x 1024h
Default-Landscape.png ** — 1024w x 748h
Default-LandscapeLeft.png — 1024w x 748h
Default-LandscapeRight.png — 1024w x 748h
iPad-Retina–Portrait.png — 1536w x 2048h
iPad-Retina–Landscape.png — 2048w x 1496h
Default.png — Not recommended
*—If you have not specified a Default-PortraitUpsideDown.png file, this file will take precedence.
**—If you have not specified a Default-LandscapeLeft.png or Default-LandscapeRight.png image file, this file will take precedence.
This link to "Apple's Developer Library" is useful, too.
As of July 2013 (iOS 6), this is what we always use:
IPHONE SPLASH
Default.png - 320 x 480
Default#2x.png - 640 x 960
Default-568h#2x.png - 640 x 1096 (with status bar)
Default-568h#2x.png - 640 x 1136 (without status bar)
IPAD SPLASH
iPadImage-Appname-Portrait.png * 768w x 1004h (with status bar)
iPadImage-Appname-Portrait#2x.png * 1536w x 2008h (with status bar)

For iOS7 create launch images in the following sizes:
For iPhone 5 and iPod touch (5th generation):
640 x 1136 pixels
For other iPhone and iPod touch devices:
640 x 960 pixels
320 x 480 pixels (standard resolution)
For iPad portrait:
1536 x 2048 pixels
768 x 1024 pixels (standard resolution)
For iPad landscape:
2048 x 1536 pixels
1024 x 768 pixels (standard resolution)
See iOS 7 Design Resources > iOS Human Interface Guidelines > Launch Images
UPDATE 1
For iPhone 6:
750 x 1334 (#2x) for portrait
1334 x 750 (#2x) for landscape
For iPhone 6 Plus:
1242 x 2208 (#3x) for portrait
2208 x 1242 (#3x) for landscape
UPDATE 2
For iPhone X:
1125 x 2436 (#3x) for portrait
2436 x 1125 (#3x) for landscape
You can make them 1024 x 768. You can also check "Status bar is initially hidden" in the plist file.
Update 2020 - Xcode 11
In Xcode 11, you can provide only one image with 1x, 2x, and 3x scales then set it in LaunchScreen.storyboard to fill up the screen and everything goes well!
For Example: (1242pt x 2688pt #1x)
This is the portrait screen size of iPhone 11 Pro Max which is the large iPhone screen size yet so it will give you high-quality splash screen on all iOS devices.
Update 2019 - iOS 12
I have collected all sizes needed for the splash screen. All u need is to just drag images with these sizes and drop them, Xcode will place each size in the right place.
Good luck.
Sizes :
320×480
640×960
640×1136
750×1334
768×1004
768×1024
828×1792
1024×748
1024×768
1125×2436
1242×2208
1242×2688
1536×2008
1536×2048
1792×828
2048×1496
2048×1536
2208×1242
2436×1125
2688×1242
Note
Count of required images are 26 images
but there are 6 duplicated sizes
so u will find the above sizes are only 20.
Here I can add Resolutions and Display Specifications for iphone 6 & 6+ size:
iPhone 6+ - Asset Resolution (#3x) - Resolution (2208 x 1242)px
iPhone 6 - Asset Resolution (#2x) - Resolution (1334 x 750)px
iPad Air / Retina iPad (1st & 2nd Generation / 3rd & 4th) - Asset Resolution (#2x) - Resolution (2048 x 1536)px
iPad Mini (2nd & 3rd Generation) - Asset Resolution (#2x) - Resolution (2048 x 1536)px
iPhone (6, 5S, 5, 5C, 4S, 4) - App Icon (120x120 px) - AppStore Icon (1024x1024 px) - Spotlight (80x80 px) - Settings (58x58 px)
iPhone (6+) - App Icon (180x180 px) - AppStore Icon (1024x1024 px) - Spotlight (120x120 px) - Settings (87x87 px)
For Xcode 9 and latest devices
Portrait
iPhone 4/4S 640 x 960
iPhone 5/5C/5S iPod touch 5th generation 640 x 1136
iPhone 6/7/8 750 x 1334

With iOS 7+, static Launch Images are now deprecated.
You should create a custom view that composes slices of images, which sizes to all screens like a normal UIViewController view.
https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/MobileHIG/LaunchImages.html
With universal app I had iPad splash screen showing up in simulator but not on device. The iPad would instead show the Default.png splash for the iPhone. The Default-Landscape.png and Default-Portrait.png files existing, so wth? Resolution should be correct since I created the screen captures using Window | Organizer | Screenshots and used 'Save as Default Image' for the iPad, then just renamed it.
Turns out (from my one app anyways) the two iPad screen shots have to be moved to the Resources-iPad directory. Then it all works fine. Seems obvious now, but in case anyone else has lost sleep over this...

For Adobe AIR iOS Developers, take note that if your iPad Splash images "shift" or display and scale a second later, it's because there are different dimensions depending on what version of AIR you're using.
Default-Portrait.png:
768 x 1004 (AIR 3.3 and earlier)
768 x 1024 (AIR 3.4 and higher)
Default-Portrait#2x.png:
1536 x 2008 (AIR 3.3 and earlier)
1536 x 2048 (AIR 3.4 and higher)

I am sure this info is somewhere but I can't find it, and the Apple Developer hotline seems to have no idea what I'm talking about. In the assets library for launch screen in Xcode, there are slots labeled:
iPhone Portrait ---> Retina HD 5.5 & Retina HD 4.7
iOS8
iPhone Portrait ---> 2x & Retina 4
iOS 7, 8
iPhone Portrait ---> 1x, 2x & Retina 4
iOS 5, 6
I had launch screens prepared and I have the sizes for these individual files, but I don't see how their sizes correspond to these Apple labels within Xcode. Moreover, the Apple docs here (https://developer.apple.com/library/ios/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/Appendices/Properties.html#//apple_ref/doc/uid/TP40011225-CH26-SW1 which is what Apple Developer referred me to) just refer to iphone 6 and 6s sizes, which doesn't correspond to the Xcode label organization.
This seems like it should be a 1 minute query. What am I missing and where is this super basic information?
If you select the image "slot" in the asset catalog and show the Attributes inspector (on the right-hand side), it will show (among other things) "Expected Size" for each image. Doing that, it looks like:
iPhone Portrait iOS8 Retina HD 5.5: 1242 x 2208
iPhone Portrait iOS8 Retina HD 4.7: 750 x 1334
In the Attributes inspector, you can also choose which "slots" you want included via a series of checkboxes.
Documentation-wise, see the Icon and Image Sizes section of the iOS Human Interface Guidelines.
Paraphrasing from there:
iPhone 6 Plus: Use a Launch File
iPhone 6: Use a Launch File
iPhone 5: 640 x 1136
iPhone 4s: 640 x 960
iPad (#2x): 1536 x 2048 (portrait), 2048 x 1536 (landscape)
iPad (#1x): 768 x 1024 (portrait), 1024 x 768 (landscape)
Also see the Launch Images section, which says:
Although it’s best to use a launch file for iPhone 6 and iPhone 6 Plus, you can
instead supply static launch images if necessary. If you need to create static
launch images for these devices, use the following sizes:
For iPhone 6:
750 x 1334 (#2x) for portrait
1334 x 750 (#2x) for landscape
For iPhone 6 Plus:
1242 x 2208 (#3x) for portrait
2208 x 1242 (#3x) for landscape
It's worth noting that if you're only supporting iOS 8, you can just use a launch XIB or Storyboard and you don't need to worry about particular images sizes. The Launch Images section has information on that.
My most recent app update (which is iOS 8 only) is using XIB files (one for iPhone, one for iPad) and it works great.
Retina HD 5.5 - 1242x2208

iTunes Connect asks me for screen shots before publishing my app for distribution in the app store. I know that the screen shot dimension for iPhone 4 in is 640x1136, but what are the screen shot dimension for the newer iPhone 4.7 in and 5.5 in?

Note: To build Apps that utilize the full screen size of the new phones add LaunchImages in the sizes: 1242 x 2208, 2208 x 1242 and 750 x 1334. The size in simulator will be different before these LaunchImages are added, because older Apps are scaled.
You may find this info useful too, taken from Andy Orsow's article (thank you buddy!) What are the iOS screen sizes?:
The sizes below include the iOS status bar area, so be sure to leave room for that in your designs. See the bottom of this article for status bar information.
Remember, mobile projects can scroll, so the screen heights listed below are simply minimum heights for your designs.

Status Bar Info
InVision will overlay a status bar on your designs for you, so including it in your design is up to you. However, you’ll want to make sure you account for the status bar at the top of your screen.
At the top of your design, leave room for:
iPhone 6 Plus: 60px height
iPhone 4–6: 40px height
iPhone - Non retina: 20px height
Retina iPads: 40px height
Non-retina iPads: 20px height
If you don't want to include the status bar in your designs, check the box for “My design starts below the status bar” in your project options.
EDITED: I had to add Launch Images to my app, and I was not able to find info how simulators correspond to Apple's image names in Launch Images assets. I found such info at http://www.ios-developer.net/iphone-ipad-programmer/icons_and_graphics/default-image and added here.
This should be a comment to Mixaz's answer but I don't have the rep for that yet. Interestingly enough, from Full resolution screenshots for Iphone 6 and 6+
I just figured this out. In Settings > Display & Brightness, you have to have the setting of Standard. I had my device set to zoomed. With "Zoomed" you get 640x1136 screen grabs. With "Standard", you get 750x1334. Not obvious to me! – Chris Prince Nov 18 '15 at 5:03
On iPhone 5s using iOS7 (not tested 6) my application has black bars on the left and right sides of the screen reducing the screen size, but is correctly opening fullscreen on every other iOS device I have so far tested. Screenshot below.
I have been searching and have not found any mention of this as a bug, have replicated on two iPhone 5's iOS7 devices though and is definitely a problem.
I'm using Air 3.9.
Has anyone encountered this / know how to fix?
I had to include an extra iOS splash screen
Default-568h#2x.png
There is a full list of images here: http://help.adobe.com/en_US/air/build/WS901d38e593cd1bac1e63e3d129907d2886-8000.html, apparently a few Air apps have been getting rejected because they are missing the new iOS7 size images.

what size should I export my graphics, for use in the example/screenshot section of the app on the app store.
Thanks
You should read the dedicated Apple documentation about the subject that gives every info about the icon sizes
Read this Technical Note too where every icon and artwork sizes are described in detail.
For the screenshots published on the AppStore, simply do a screenshot of your app for this (which will be 640x960px if you make your screenshot from an iPhone with Retina display (iPhone4), and 320x480px for iPhone 3GS or older, etc. Namely the size of the screen in pixels, obviously).
To do those screenshots:
either directly on the device hold the Power+Home buttons together and it will display a small/quick "flash" effect on the screen to tell you the screenshot has been saved in your iPhone library
Or from the Xcode Organizer, after you have plugged the iPhone to your Mac obviously, select the iPhone in the list and in the appropriate section of the organizer, click on the button to generate a screenshot directly from Xcode.

Hello wonderful stackoverflowers!
I hope this question is within the scope of this site.
I'm preparing to submit my first iPhone app to the AppStore and I want to make sure that I have all the graphics needed. I also want to make sure that I have the required graphics for the iPad and to be featured (if I get lucky :).
Could we confirm that this list looks correct and comprehensive? Is there anything here in excess or that neeeds to be added? Any warnings or caveats from previous experiences?
Please keep in mind that I am looking for the widest possiblity of distribution.
For the sake of simplicity I'm going to submit everything as a .png. Would that be okay?
If you provide large graphics for the Retina display on the iPhone 4 do you also need to supply the smaller ones? Likewise for the screen shots?
