iphone deployment version requirements

Is there a specific version that the deployment requirements need to be set to in xcode to submit an app to the app store? I keep getting a "not accepting this SDK" error w开发者_运维百科hen I try to upload the binary but my target deployment OSs are all recent (3.0, 4.0).

Make sure your Base SDK is 4.0. Deployment Target can be whatever minimum OS your app requires.

Make sure you have installed an official release of the SDK. Apple does not accept submissions from pre-release SDK's unless expressly stated (e.g. 4.0 GM)
