swift -> 电话号码,邮箱地址 ， 等， 正则判断

import Foundation

enum Validate {
    case email(_: String)

    case carNum(_: String)
    case username(_: String)

    var isRight: Bool {
        var predicateStr:String!
        var currObject:String!
        switch self {
        case let .email(str):
            predicateStr = "^([a-z0-9_\\.-]+)@([\\da-z\\.-]+)\\.([a-z\\.]{2,6})$"
            currObject = str
        case let .phoneNum(str):
            //意思 第一位 1 ， 第二位 [2-9] 2到9都可以， d{9} 数字9位
            predicateStr = "^((1[2-9]))\\d{9}$"

        let predicate =  NSPredicate(format: "SELF MATCHES %@" ,predicateStr)

}

使用

Validate.email("Dousnail@@153.com").isRight //false
 
Validate.URL("https://www.baidu.com").isRight //true
 
Validate.IP("11.11.11.11").isRight //true
