swift - Swift中的#pragma mark？(#pragma mark in Swift?)

Question

In Objective C, I can use #pragma mark to mark sections of my code in the symbol navigator.

(在Objective C中，我可以使用#pragma mark在符号导航器中标记我的代码部分。)

Since this is a C preprocessor command, it's not available in Swift.

(由于这是一个C预处理器命令，因此在Swift中不可用。)

Is there a stand-in for this in Swift, or do I have to use ugly comments?

(在Swift中是否有替代，或者我是否必须使用丑陋的评论？)

Answer 1

You can use // MARK:

(你可以使用// MARK:)

There has also been discussion that liberal use of class extensions might be a better practice anyway.

(还有人讨论过，无论如何，自由使用类扩展可能是更好的做法。)

Since extensions can implement protocols, you can eg put all of your table view delegate methods in an extension and group your code at a more semantic level than #pragma mark is capable of.

(由于扩展可以实现协议，因此您可以将所有表视图委托方法放在扩展中，并将代码分组到比#pragma mark能够更加语义的级别。)
