Launch Images

Every app must provide at least one launch image. This image is typically in a file named Default.png that displays your app’s initial screen in a portrait orientation. However, you can also provide other launch images to be used under different launch conditions. All launch images must be PNG files and you should avoid using interlaced PNGs. The name of each launch image conveys its purpose and how it is used. It is recommended that you use the following format for launch image filenames:
Image

A launch image is a simple placeholder image that iOS displays when your app starts up. The launch image gives users the impression that your app is fast and responsive because it appears instantly and is quickly replaced by the first screen of your app.
Naming

<basename><usage_specific_modifiers><scale_modifier><device_modifier>.png
Different Orientations

<basename><orientation_modifier><scale_modifier><device_modifier>.png

-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. For apps running on systems earlier than iOS 3.2, you must name this file Default.png.>

Bar Button Icons
  
custom bar icon, follow these guidelines:
  • Use pure white with appropriate alpha transparency.
  • Not include a drop shadow.
  • Use antialiasing.
  • If you want to create a bar icon that looks like it's related to the iOS 7 icon family, use a very thin stroke to draw it. Specifically, a 2-pixel stroke (high resolution) works well for detailed icons and a 3-pixel stroke works well for less detailed icons.
Toolbar or navigation bar icon sizes:

About 44 x 44 pixels
About 22 x 22 pixels (standard resolution)
Tab bar icon sizes:

About 50 x 50 pixels (96 x 64 pixels maximum)
About 25 x 25 pixels (48 x 32 pixels maximum) for standard resolution
