ipad default-landscape not displaying

I have added both images. Default-Portrait.png and Default-Landscape.png. But whenever I star开发者_如何学Pythont my app, only the portrait default image is displayed irrespective of the orientation.

Why is this happening?

I had the same problem and solved it by adding the following to the Info.plist file (from Xcode):

<key>UISupportedInterfaceOrientations</key>
<array>
    <string>UIInterfaceOrientationPortrait</string>
    <string>UIInterfaceOrientationPortraitUpsideDown</string>
    <string>UIInterfaceOrientationLandscapeLeft</string>
    <string>UIInterfaceOrientationLandscapeRight</string>
</array>

Did you add code to swap out the images based on orientation? I am guessing the app just is not going to know what picture you want unless you tell it.
