快速关闭有什么特殊用途吗？有什么好处？

问题描述

我已经学习Swift一段时间了，并且已经阅读了Swift语言指南。

I have learnt Swift for a while and I have read the Swift language guide.

概念关闭对我来说是新的。我想我可以使用，但是在哪里可以使用？它有什么好处？

The concept closure is new to me. I think I can understand how to use it, but where I can use it? what is the benefit of it?

我用Google搜索并得到了答案

I googled and get the answer When to use closures in swift?

我认为答案并不令人满意。语言指南对此做了很多介绍，我想它是该语言的一个非常重要的功能，也许它已在框架中广泛使用。

I do not thinks the answer is satisfying. The language guide writes so much about it, I guess it is a very important feature of the language, and maybe it's widely used in the framework.

有人可以给我更多的例子来展示它的力量吗？
非常感谢。

Could anyone show me more example to show it's power?Thanks a lot.

推荐答案

问题可能有点广泛，但我将尝试重述。

The question might be a little broad, but I will try to recap.

引用

• animateWithDuration:animations:completion:
• urlSession(_:dataTask:didReceive:completionHandler:)
• sort(by:)

再次获得：这只是闭包的简单用法；您需要查看文档以获取更多详细信息。

AGAIN: it is just a simple usage of the closures; You need to check the documentation for more details.

我希望它能对您有所帮助。

I hope it helped.
