iOS 是 Apple 为其移动设备平台（iPhone、iPad 和 iPod touch）开发的一系列移动操作系统。它以前被称为 iPhone OS，与第一代 iPhone 一起推出。这个名字一直保留到 2010 年初 iPad 发布时，当时苹果将其更名为 iOS。在 2019 年，苹果开始使用 iPadOS 这个名字来标记 iPad 设备上使用的操作系统版本。
iOS is based on the codebase of macOS, formerly OS X, and shares the same kernel, filesystem, and binary formats. The userland of iOS is like that of macOS, but with a mobile-friendly design that is touchscreen and content-centric. It lacks direct access to the filesystem and is unable to run arbitrary code by default. The only distribution method for software officially allowed on iOS is the built-in App Store.
The userland consists of a home screen (known as Springboard) that manages the user's applications. Many applications from macOS exist in iOS and vice-versa.
Since the release of iOS 11 in 2017, iOS has only been compiled for 64-bit ARM-based processors. Since the release of iOS 16 in 2022, iOS has only been compiled for iPhone models.
No official emulator that can run the retail version of iOS exists. However, Apple provides the iOS Simulator with Xcode, which runs a modified build of iOS with output in a dedicated window. Unofficial emulators like Corellium and QEMU-T8030 can emulate iOS to an extent. There is also an open source fork of QEMU[1] that can emulate a 1st generation iPod Touch on iPhone OS 1.1.
