Sizes and Naming of Launch Image for iPhone app in iOS8

Question

What are sizes/naming of the launch images used for iPhone app in iOS?

Solution 1

Size Conventions

iPhone3g : 320 x 480

iPhone4/4s : 640 x 960

iPhone5/5s : 640 x 1136

iPhone6 : 750 x 1334

iPhone 6plus : 1242 x 2208

Naming Conventions

For developers who don't wan't to use 'Asset Catalogs', they need to give specific names to launch images

iPhone3g : 'Default.png'

iPhone4/4s : '[email protected]'

iPhone5/5s : '[email protected]'

iPhone6 : '[email protected]'

iPhone6plus : '[email protected]'

For developers who would use 'Asset Catalogs', they don't need to give specific names to launch images

Go to ProjectSetting -> General-> Under 'App Icons and Launch Images', select 'Use Asset Catalog' for 'Launch Image Source', and drag-drop the launch images for their OS version's/Orientations

Solution 2

If you use images.xcassets then you neither need to worry about the naming conventions nor to add those images into your project resource explicitly. Just drag and drop the appropriate size image to the appropriate box and XCode will do the rest.

And for image sizes please refers the Apple iOS Human Interface Guidelines
