Startup screen of iPhone, iPhone 4, and iPad

IOS devices have three different resolutions: iPhone 320x480, iPhone 4 640x960, and iPad 768x1024. PreviousProgramOnly one default.png image can be used, but it is much more complicated now.

If a program supports both iPhone and iPad, it must contain the following images:

Default-Portrait.png iPad dedicated vertical boot screen 768x1024 or 768x1004

Default-Landscape.png iPad dedicated landscape boot screen 1024x768 or 1024x748

Default-PortraitUpsideDown.png iPad dedicated vertical boot screen (Home button on screen), can omit 768x1024 or 768x1004

Horizontal boot screen for Default-LandscapeRight.png iPad, omitted 1024x768 or 1024x748
