无法将'NSRange'(又名'_NSRange')类型的值转换为预期的参数类型'Range <Index>'(又名'Range <String.CharacterView.Index>')

Question

我的代码中有一个错误,例如"无法将类型'NSRange'(又名'_NSRange')的值转换为预期的参数类型'Range'(又名'Range')"但我不知道如何解决这个问题请任何一个帮我？

在这里,我发布我的代码.

NSUserDefaults.standardUserDefaults().setObject("Hey I have started using this Chat App", forKey: "Status")
            var strNumber: String = txtPhoneNumber.text!
            var myRange: NSRange = NSMakeRange(0, 2)
            var myRange1: NSRange = NSMakeRange(0, 1)
            var ran: String = strNumber.substringWithRange(myRange)  ------>  //This line error shows.
            var ran1: String = strNumber.substringWithRange(myRange1)
            if (ran == "00") || (ran == "60") || (ran == "62") || (ran == "65") || (ran == "91") || (ran == "44") {
                strNumber = strNumber.stringByReplacingOccurrencesOfString(ran, withString: "") as String
            }
            else if (ran1 == "0") {

                strNumber = strNumber.stringByReplacingOccurrencesOfString(ran1, withString: myRange1) as NSString
                //str_number = str_number.stringByReplacingOccurrencesOfString(ran1, withString: "", options: NSCaseInsensitiveSearch, range: myRange1)
            }

Answer 1

你应该转换strNumber为NSString:var strNumber: NSString = txtPhoneNumber.text!

更多信息:NSRange到Range <String.Index>

Answer 2

斯威夫特4:

首先对一个字符串进行类型转换,然后在这个类型化的字符串上使用class方法

let typeCasteToStringFirst = textField.text as NSString?
let newString = typeCasteToStringFirst?.replacingCharacters(in: range, with: string)
