Question

I want to replace variable name between {{}} to its value, just like: I can using Dictionary like:

//var a = 10
//var b = 20
var pairs:[string:int]=["a":10,"b":20]
var str = "I have {{a}} apples and {{b}} pears"

And Target is "I have 10 apples and 20 pears" How Can I Do It In Swift Using Regex?

Answer 1

正如Alexander指出的,如果你重新试图采取从方案外读到的任意强权,并且根据方案内部的变数采用替代法,那么这种替代就在迅速不可能。你们需要以不同方式储存数据(如假冒)。图书馆如GRMustache 这表明可以做到这一点,并具体处理你重新描述的那种辛迪加。

However, if this String is known at compile-time, you can apply string interpolation to it:

var str = "I have (a) apples and (b) pears"

这纯粹是一个汇编时代的特点。你们不能像现在这样阅读一种扼制格式,并且出现替代物。这将使数据能够查阅该守则,而该守则基本上不允许迅速查阅。
