load image/splash screen does not appear on ipad

I have a 1024x768 default load image for the iPad that displays in Xcode, but doesn't display on the iPad. There is a warning icon in Xcode4, but there is no explanation pro开发者_开发技巧vided. What is wrong?

Don't trust Xcode 4 to name your files correctly. Here's how you should be naming the default images on iPad:

http://developer.apple.com/library/ios/#qa/qa1588/_index.html

• Default-PortraitUpsideDown.png - upside-down portrait version.
• Default-LandscapeLeft.png - left-oriented landscape version.
• Default-LandscapeRight.png - right-oriented landscape version.
• Default-Portrait.png - generic portrait version.
• Default-Landscape.png - generic landscape version
• Default.png - default portrait launch. Its usage is strongly discouraged, use more specific launch images instead.
