Remove Special Characters in NSString

Question

how to remove this characters in nsstring and get

Answer 1

I'm sure there's a more elegant solution, but for anyone trying to do this in Swift, here's what I did to make sure there were no special characters in my users' phone numbers.

var phone = "+1 (555) 555 - 5555"
var removeChars: NSCharacterSet = NSCharacterSet(charactersInString: "1234567890").invertedSet
var charArray = phone.componentsSeparatedByCharactersInSet(removeChars)
var placeholderString = ""
var formattedPhoneNumber: String = placeholderString.join(charArray).stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())

The stringByTrimmingCharactersInSet might not be necessary.
