Remove all whitespaces from NSString

Question

I\'ve been trying to get rid of the white spaces in an NSString, but none of the methods I\'ve tried worked.

I have \"this is a test\" and

Answer 1

This for me is the best way SWIFT

        let myString = "  ciao   \n              ciao     "
        var finalString = myString as NSString

        for character in myString{
        if character == " "{

            finalString = finalString.stringByReplacingOccurrencesOfString(" ", withString: "")

        }else{
            finalString = finalString.stringByReplacingOccurrencesOfString("\n", withString: "")

        }

    }
     println(finalString)

and the result is : ciaociao

But the trick is this!

 extension String {

    var NoWhiteSpace : String {

    var miaStringa = self as NSString

    if miaStringa.containsString(" "){

      miaStringa =  miaStringa.stringByReplacingOccurrencesOfString(" ", withString: "")
    }
        return miaStringa as String

    }
}

let myString = "Ciao   Ciao       Ciao".NoWhiteSpace  //CiaoCiaoCiao
