The portion of the filename is either the string Default or a custom string that you specify using the UILaunchImageFile key in your application’s Info.plist file. The portion is the optional string @2x and should be included only for images intended for use on Retina displays. Other optional modifiers may also be included in the name, and several standard modifiers are discussed in the sections that follow.

Device	Portrait	Landscape
iPhone and iPod touch	320 x 480 pixels 640 x 960 pixels (high resolution)	Not supported
iPad	768 x 1004 pixels	1024 x 748 pixels

Modifier	Description
-PortraitUpsideDown	Specifies an upside-down portrait version of the launch image. A file with this modifier takes precedence over a file with the -Portrait modifier for this specific orientation.
-LandscapeLeft	Specifies a left-oriented landscape version of the launch image. A file with this modifier takes precedence over a file with the -Landscape modifier for this specific orientation.
-LandscapeRight	Specifies a right-oriented landscape version of the launch image. A file with this modifier takes precedence over a file with the -Landscape modifier for this specific orientation.
-Portrait	Specifies the generic portrait version of the launch image. This image is used for right-side up portrait orientations and takes precedence over the Default.png image file (or your custom-named replacement for that file). If a file with the -PortraitUpsideDown modifier is not specified, this file is also used for upside-down portrait orientations as well.
-Landscape	Specifies the generic landscape version of the launch image. If a file with the -LandscapeLeft or -LandscapeRight modifier is not specified, this image is used instead. This image takes precedence over the Default.png image file (or your custom-named replacement for that file).
(none)	If you provide a launch image file with no orientation modifier, that file is used when no other orientation-specific launch image is available. Before iOS 3.2, this is the only supported launch image file type and must be named Default.png.

The following device modifiers are recognized for launch images in iOS 4.0 and later:

• ● ~ipad. The launch image should be loaded on iPad devices only.

• ● ~iphone. The launch image should be loaded on iPhone or iPod touch devices only.

App ID

• Bundle seed ID - 10 hex digit (generated by apple)
• Bundle Identifier - suffix, reverse dns (e.g. com.clampett.applicationname)

Wildcard (*) can be used for Bundle Identifier to use this for a suite of applications.
