Answer 1

There are two settings that control this the Base SDK and iPhone OS Deployment Target, both accessible in Project settings within XCode.

You want to keep your Base SDK set to the latest stable version at all times and then set your deployment target to the older version you want to support.

In this case:

Base SDK = 3.1.3

iPhone OS Deployment Target = iPhone OS 3.0

This is the practice recommended by Apple. If there are features that you want to use that are available in the newer SDK but not in an older version you can test specifically for those features.

Answer 2

您可以使用3.1.3 SDK为iphone 3.0操作系统直接编译应用程序。
