s9splashgen - Splash screen generator

Introduction

The Ruby script s9splashgen automatically generates splash screens of all necessary sizes for iPhone and/or iPad apps (iOS 7 and above). It uses imagemagick and the gem rmagick.

Installation

Install imagemagick and rmagick via

brew install imagemagick
gem install rmagick

Usage

Just run the script

./s9splashgen.rb my_splash.png

The first argument is the filename of the splash screen image (for best results use an image in portrait mode of size of at least 1536x2048 [1242x2208 iphone only]). By default only iPhone splash screens are generated. If one supplies a second argument (ipad or universal), iPad splash screens or iPhone/iPad splash screens are generated respectively.

Example

The command

./s9splashgen.rb my_splash.png universal

will generate

  320x480(2x) ->   640x960: screens/Default@2x~iphone.png
  320x568(2x) ->  640x1136: screens/Default-568h@2x~iphone.png
  375x667(2x) ->  750x1334: screens/Default-667h@2x~iphone.png
  414x736(3x) -> 1242x2208: screens/Default-736h@3x~iphone.png
 768x1024(1x) ->  768x1024: screens/Default-Portrait~ipad.png
 1024x768(1x) ->  1024x768: screens/Default-Landscape~ipad.png
 768x1024(2x) -> 1536x2048: screens/Default-Portrait@2x~ipad.png
 1024x768(2x) -> 2048x1536: screens/Default-Landscape@2x~ipad.png

RubyMotion

Add the splash screens to your resources folder. Since RubyMotion 2.34 there is no need to modify your rakefile, if you only want iPhone and iPad portrait launch images. For a universal app with additional iPad landscape launch images you have to add the following lines to your rakefile.

app.info_plist['UILaunchImages'] = [
  # iphone
  {
    'UILaunchImageName' => 'Default',
    'UILaunchImageOrientation' => 'Portrait',
    'UILaunchImageMinimumOSVersion' => '7.0',
    'UILaunchImageSize' => '{320, 480}'
  },
  {
    'UILaunchImageName' => 'Default-568h',
    'UILaunchImageOrientation' => 'Portrait',
    'UILaunchImageMinimumOSVersion' => '7.0',
    'UILaunchImageSize' => '{320, 568}'
  },
  {
    'UILaunchImageName' => 'Default-667h',
    'UILaunchImageOrientation' => 'Portrait',
    'UILaunchImageMinimumOSVersion' => '8.0',
    'UILaunchImageSize' => '{375, 667}'
  },
  {
    'UILaunchImageName' => 'Default-736h',
    'UILaunchImageOrientation' => 'Portrait',
    'UILaunchImageMinimumOSVersion' => '8.0',
    'UILaunchImageSize' => '{414, 736}'
  },
  # ipad
  {
    'UILaunchImageName' => 'Default-Portrait',
    'UILaunchImageOrientation' => 'Portrait',
    'UILaunchImageMinimumOSVersion' => '7.0',
    'UILaunchImageSize' => '{768, 1024}'
  },
  {
    'UILaunchImageName' => 'Default-Landscape',
    'UILaunchImageOrientation' => 'Landscape',
    'UILaunchImageMinimumOSVersion' => '7.0',
    'UILaunchImageSize' => '{768, 1024}'
  }
