You need to set the Deployment target in the build settings to the minimum iOS version you require.
您需要在构建设置中将部署目标设置为您需要的最低 iOS 版本。
A general guideline is to set:
一般准则是设置：
- Base SDK to latest
- deployment target to the minimum version you support.
- 基础 SDK 到最新
- 部署目标到您支持的最低版本。
Also - check your Info.plist file for the MinimumOSVersionkey.
另外 - 检查您的 Info.plist 文件以获取MinimumOSVersion密钥。

Do you get build errors when you try to build for version 3.1.3 in xcode.
当您尝试在 xcode 中为 3.1.3 版构建时，是否会遇到构建错误。
iOS4 SDK has a lot of features that possibly are not featured in older versions of the the firmware.
iOS4 SDK 有很多旧版本固件可能没有的功能。
