在IOS Swift中放置可重用功能的位置？ [英] Where to put reusable functions in IOS Swift?

问题描述

IOS编程的新手，但只是想知道在我的代码中放置函数的最佳位置。例如，我想编写一些函数来对Web服务执行POST请求并返回字典。也许是另一个做一些计算的功能。是否最好创建另一个.swift文件并将所有功能放在那里。如果是这样，那么给出文件的好名字是什么？

New to IOS programming but just wondering where is the best place to put functions that I would use throughout my code. For example, I want to write a few functions to perform a POST request to a web service and return a dictionary. Maybe another function to do some calculations. Is it best to create another .swift file and put all my functions there. And what would be a good name to give the file if so?

public func postRequest() -> [String:String] {
     // do a post request and return post data
     return ["someData" : "someData"]
}

推荐答案

最好的方法是使用静态函数创建一个辅助类，如下所示：

The best way is to create a helper class with static functions, like this:

class Helper{
    static func postRequest() -> [String:String] {
         // do a post request and return post data
         return ["someData" : "someData"]
    }
}

现在，每当你需要使用 postRequest 时，你可以这样使用： Helper.postRequest（）

Now every time you need to use postRequest you can just use like so: Helper.postRequest()

我希望能帮到你！
