While building an iOS app, the architectures (armv7, armv7s, armv64) you choose dictate what all platforms you will be supporting. The "Deployment target" version that you select in xcode is the minimum OS version that you can support. An iOS app is a universal binary, which means that it can contain code supporting both 32-bit and 64-bit architectures. Building with 64 bit support (iOS 8 SDK) is not the same as dropping support for earlier 32-bit OS versions.
在构建iOS应用程序时,您选择的架构(armv7,armv7s,armv64)决定了您将支持的所有平台。您在xcode中选择的“部署目标”版本是您可以支持的最低操作系统版本。 iOS应用程序是通用二进制文件,这意味着它可以包含支持32位和64位体系结构的代码。使用64位支持构建(iOS 8 SDK)与删除对早期32位操作系统版本的支持不同。
