I am developing an application using the iOS SDK. I need to know what Default splash screen sizes I n开发者_如何学运维eed.

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)
iPadImage-Appname-Landscape.png ** 1024w x 748h (with status bar)
iPadImage-Appname-Landscape@2x.png ** 2048w x 1496h (with status bar)

iPadImage-Appname-Portrait.png * 768w x 1024h (without status bar)
iPadImage-Appname-Portrait@2x.png * 1536w x 2048h (without status bar)
iPadImage-Appname-Landscape.png ** 1024w x 768h (without status bar)
iPadImage-Appname-Landscape@2x.png ** 2048w x 1536h (without 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 X 2436 x 1125

iPad non-retina 1024 x 768

iPad retina 2048 x 1536

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.

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... -Larry

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)
