ios - 替换出现的逗号或点

Question

我有以下代码:

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

我可以另外替换出现的逗号吗？ 或者是唯一的解决方法:

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

Answer 1

您可以使用支持正则表达式的replacingOccurrences，在本例中为[,.]

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

那么完整的代码就是

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