替换出现的逗号或点

Question

I have the following code:

let kmInput: Int = (addKmInput.text!.replacingOccurrences(of: ".", with: "") as NSString).integerValue

Can I additionally replace occurrences of commas? Or is the only way to solve it this way:

let kmInput: Int = (addKmInput.text!.replacingOccurrences(of: ".", with: "").replacingOccurrences(of: ",", with: "")

Answer 1

Yo can use replacingOccurrences that supports regular expressions, in this case [,.]

let result = string.replacingOccurrences(of: "[.,]", with: "", options: .regularExpression)

the full code would then be

let kmInput = Int(addKmInput.text!
    .replacingOccurrences(of: "[.,]", 
                          with: "", 
                          options: .regularExpression))
