Cocoa实用工具类(Cocoa Utility Class)

我想我在这里遗漏了一些非常基本的东西。 我有一个Utilities类,它有一些从几个不同的类调用的函数。 我希望能够包含Utilities.h并只是说[Utilities doStuff]并在Utilities.m中执行doStuff功能,这是最简单的方法吗?


I think I'm missing something pretty basic here. I have a Utilities class that has some functions that are called from a few different classes. I want to be able to include Utilities.h and just say [Utilities doStuff] and have the doStuff function in Utilities.m be executed, what's the easiest way to do this?

最满意答案

只需在你的function之外声明你的var d ,然后你可以在以后使用它

var d;

function getDistance(origin, destination) {
    // ...

    d = response.routes[0].legs[0].distance.value;
}

您现在可以在其他方法或代码中的其他位置使用d


Just declare your var d outside your function, then you could use it later

var d;

function getDistance(origin, destination) {
    // ...

    d = response.routes[0].legs[0].distance.value;
}

You can now use d in another method or elsewhere in your code.
