PS:
[Translation reason-translation itself is also a process of Reinforcement Learning]
I have been diving on cocoachina before. Although I have been developing IOS for almost two years, I always feel that something is missing. I used to view the API documentation in English, but I can't remember some details. One day someone complained to me that it was too painful to view the official English API documentation. Then I thought that if I translated some frequently-used official documents into Chinese, maybe it can help these people who need help, and then they even began their own entertaining translation journey. While helping others, you are also happy.

Multi-threaded programming is very helpful when developing applications. For example, you can load images in the background, update images in the main thread after they are loaded, or process some events that require a long CPU usage (such as the request server, load data ). We need to understand the advantages of multi-threaded programming, but also more practical practices, combined with the use of a variety of multi-threaded technology. Pay special attention to run
Many developers seldom pay attention to the run loop when writing multi-threaded applications. If you carefully read and grasp the details of the run loop, it will help you write better code. Synchronization is a commonplace in multi-thread programming. It is estimated that everyone in college is familiar with the importance of synchronization.

During the translation process, this article finds that many Chinese translations are obscure, so the free translation method is adopted. This inevitably leads to some discrepancies with the original article, if you find any errors during reading, you can send me an email:Xyl.layne@gmail.com

You can also pay attention to my weibo posts for communication and learning.

Finally, I hope this document will help those who feel difficult to read the official English documents. If you can, I recommend that you view the original English documents as much as possible. After all, it is original and translation cannot avoid some omissions.

Coming soon: core data programming guide

Because the translation is written in word, the format is too large, so it is difficult to upload images, so we can directly convert them to PDF for you to download.
