在Swift中将Int转换为字符串

在Swift中将Int转换为字符串

问题描述:

我试图找出如何在Swift中将 Int 转换为 String

I'm trying to work out how to cast an Int into a String in Swift.

我想出了一个解决方法,使用 NSNumber 但我想知道如何做到这一切在Swift。 / p>

I figure out a workaround, using NSNumber but I'd love to figure out how to do it all in Swift.

let x : Int = 45
let xNSNumber = x as NSNumber
let xString : String = xNSNumber.stringValue


转换 code>到字符串

let x : Int = 42
var myString = String(x)

c $ c> String 至 Int

And the other way around - converting String to Int:

let myString : String = "42"
let x: Int? = myString.toInt()

if (x != nil) {
    // Successfully converted String to Int
}

或者如果您使用的是Swift 2:

Or if you're using Swift 2:

let x: Int? = Int(myString)
