是否有最低 iOS sdk？
Is there a minimum iOS sdk?
我正在开发一个 iOS 应用程序，一位朋友告诉我 Apple 有最低 SDK 要求。真的吗？谢谢。
It's not minimum iOS SDK. but It's minimum deployment target. which
indicate minimum iOS version supported by your application. from that
onwards you must support you application.
例如。如果您的应用程序最低部署目标是 7.0，那么您的应用程序必须 运行 on iOS 7.0 到最新的 iOS SDK，即 iOS 9.2。
