swift - 无法将类型 'NSRange'(又名 '_NSRange')的值转换为预期参数类型 'Range'(又名 'Range')

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人帮助我？

我在这里发布我的代码。

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)
            }

您应该将 strNumber 转换为 NSString:var strNumber: NSString = txtPhoneNumber.text!
