GCD的移植与实现

Porting Grand Central Dispatch to ObjFW

GCD(Grand Central Dispatch)模型是苹果公司于2013年首先在苹果系统编程中提出的概念.GCD模型有效简化了开发编程、并行编程以及多线程编程的模型,使开发人员进行开发,并行编程更加方便,容易。虽然苹果公司公开了GCD的代码,但是GCD部分开源代码完全基于苹果公司的闭源开发库:Foundation之上,无法独立使用。本文基于开源的GCD方案,移植到开源Objective-C的开发框架ObjFW之上。

The GCD（Grand Central Dispatch） model was first introduced by Apple in the Apple system programming in 2013. The GCD model effectively simplifies concurrent programming, parallel programming, and multithreaded programming models, making it easier for developers to concurrently and concurrently program, Easy.While Apple released the GCD code, part of the GCD open source code is completely based on Apple＇s closed source development library：Foundation, can not be used independently.This article is based on the open source GCD program, porting to the development of open source Objective-C Framework Obj FW above.
