检查是否存在目标c enum [英] Check if a objective c enum exists

问题描述

我为按钮ID预定了枚举：

I have predefined enum for buttons IDs:

typedef enum
{
    button1ID = 407,
    button2ID = 999,
    button3ID = 408,
    button4ID = 409,
} TOP_MENU_BUTTON_TYPE;

我需要查明我收到的ID是否在枚举中被定义。我怎样才能做到这一点？类似于：

I need to find out if the ID I recieve is defiened in the enum. How can I do that? Something like:

if(id in TOP_MENU_BUTTON_TYPE)

推荐答案

如果我清楚地理解你的问题，那么这对你有帮助..

If I understand your question clearly, then this would be helpful to you..

不要单独使用 enum ，而应该尝试使用 struct ，这是@Richard的回答将帮助您如何做到这一点。

Instead of using enum alone, you should try that with struct and here it is an answer by @Richard will help you how to do that.

在运行时更改枚举值？

在上面的链接中，他解释了如何使用动态枚举带有 struct 的值，还可以迭代要查找的值。我想你会有个主意。

In the above link, he explains how to use a dynamic enum values with struct and also you can iterate the values to find out. I think you will get an idea.
