Swift常用正则表达式

代码如下:

import UIKit

class MMTest: NSObject {

//MARK:- 正则匹配手机号
class func checkMobile(_ mobileNumbel:NSString) ->Bool
{
    /**
     * 手机号码
     * 移动：134[0-8],135,136,137,138,139,150,151,157,158,159,182,187,188
     * 联通：130,131,132,152,155,156,185,186
     * 电信：133,1349,153,180,189,181(增加)
     */
    let MOBIL = "^1(3[0-9]|5[0-35-9]|8[025-9])\\d{8}$";
    /**
     * 中国移动：China Mobile
     * 134[0-8],135,136,137,138,139,150,151,157,158,159,182,187,188
     */
    let CM = "^1(34[0-8]|(3[5-9]|5[017-9]|8[2378])\\d)\\d{7}$";
    /**
     * 中国联通：China Unicom
     * 130,131,132,152,155,156,185,186
     */
    let CU = "^1(3[0-2]|5[256]|8[56])\\d{8}$";
    /**
     * 中国电信：China Telecom
     * 133,1349,153,180,189,181(增加)
     */
    let CT = "^1((33|53|8[019])[0-9]|349)\\d{7}$";
    let regextestmobile = NSPredicate(format: "SELF MATCHES %@", MOBIL)
    let regextestcm = NSPredicate(format: "SELF MATCHES %@", CM)
    let regextestcu = NSPredicate(format: "SELF MATCHES %@", CU)

    }
        return false
}
//MARK:- 正则匹配用户身份证号15或18位
class func checkUserIdCard(_ idCard:NSString) ->Bool {

    let pattern = "^(?![0-9]+$)(?![a-zA-Z]+$)[a-zA-Z0-9]{6,18}"
    let pred = NSPredicate(format: "SELF MATCHES %@", pattern)
    let isMatch:Bool = pred.evaluate(with: password)
    return isMatch;

//MARK:- 正则匹配URL

//MARK:- 正则匹配用户姓名,20位的中文或英文

    let pred = NSPredicate(format: "SELF MATCHES %@", pattern)
    let isMatch:Bool = pred.evaluate(with: userName)

//MARK:- 正则匹配用户email
