Cocoa Touch是苹果电脑公司的用户界面软件框架，用于在iOS操作系统上开发应用软件来运行在iPhone, iPad和iPod Touch上。

Cocoa Touch提供了iOS操作系统的抽象层。Cocoa Touch基于 Mac OS X Cocoa API， 主要用 Objective-C进程语言写成。 相比Mac OS X上的Cocoa，Cocoa Touch增加了支持iOS设备的硬件和功能。和Cocoa一样, Cocoa Touch使用MVC软件架构模式。

Cocoa Touch具有不同于Cocoa的图形控制组件。iOS SDK包含了开发基于Cocoa Touch的应用软件的工具。

Cocoa Touch is a UI framework for building software programs to run on iOS (for the iPhone, iPod Touch, and iPad), watchOS for the Apple Watch, and tvOS for the fourth-generation Apple TV, from Apple Inc.

Cocoa Touch provides an abstraction layer of iOS, the operating system for the iPhone, iPod Touch, and iPad. Cocoa Touch is based on the Mac OS X Cocoa API toolset and, like it, is primarily written in the Objective-C language. Cocoa Touch allows the use of hardware and features that are not found in Mac OS X computers and are thus unique to the iOS range of devices. Just like Cocoa, Cocoa Touch follows a Model-View-Controller (MVC) software architecture.
