Introduction: Grand Central Dispatch (GCD) is a technology developed by Apple to optimize applications that support multi-core processors and other systems of Symmetric Multi-processing systems. This is based on the Thread Pool Mode for concurrent task execution. It is released on Mac OS X 10.6 For the first time, and is also available for iOS 4 and later versions.Design: GCD works as follows: allows programs to queue specific tasks in parallel and sc

Exploring multi-thread programming in iOS development: Grand Central Dispatch details, multi-thread programming dispatch I have published a blog about multithreading development in iOS, which introduces NSThread, Operation queue, and GCD. Today, we will give a comprehensive summary of how GCD is used. The history and benefits of GCD are not described too much here. This blog will summarize GCD through a series of examples. GCD is very important in iOS

Grand Central Dispatch (GCD) is a new solution developed by Apple for multi-core programming. It was first launched in Mac OS X 10.6 snow leopard and recently introduced to ios4.0. GCD is an efficient and powerful technology that replaces technologies such as nsthread. GCD can fully handle asynchronous programming issues such as data locking and resource leakage. GCD can accomplish many things, but this article only focuses on some basic knowledge req

The maximum number of particles in the central control granulation subsystem of Unity. The particle system in Unity is easy to use. However, a problem occurs in the actual process: it is necessary to dynamically control the maximum number of particles a particle system component can produce. It can be seen that the doc is controlled by maxparticipant, but this open parameter is not actually available and can only be implemented in other ways. Here we
