Swift常用正則表達式

1.驗證郵箱

class func validateEmail(email: String) -> Bool {
    var emailString = "[A-Z0-9a-z._% -] @[A-Za-z0-9.-] \\.[A-Za-z]{2,4}"
    var emailPredicate = NSPredicate(format: "SELF MATCHES %@", emailString)
    return emailPredicate.evaluateWithObject(email)
}

2.驗證手機號

class func validatePhonoNum(phono: String) -> Bool {
        //手機號以13,15,17,18開頭，八個 \d 數字字符
    var phoneString = "^((13[0-9])|(15[^4,\\D]) |(17[0,0-9])|(18[0,0-9]))\\d{8}$"
    var phonePredicate = NSPredicate(format: "SELF MATCHES %@", phoneString)
    return phonePredicate.evaluateWithObject(phono)
}

3.驗證車牌號
class func validateCarNum(car: String) -> Bool {
    var carString = "^[A-Za-z]{1}[A-Za-z_0-9]{5}$"
    var carPredicate = NSPredicate(format: "SELF MATCHES %@", carString)
    return carPredicate.evaluateWithObject(car)
}

4.驗證用戶名
class func validateUserName(name: String) -> Bool {
    var userNameRegex = "^[A-Za-z0-9]{6,20}+$"
    var userNamePredicate = NSPredicate(format: "SELF MATCHES %@", userNameRegex)
    var peopleName = userNamePredicate.evaluateWithObject(name)
    return peopleName
}

5.驗證密碼
class func validatePassword(passWord: String) -> Bool {
    var passWordRegex = "^[a-zA-Z0-9]{6,20}+$"
    var passWordPredicate = NSPredicate(format: "SELF MATCHES%@", passWordRegex)
    return passWordPredicate.evaluateWithObject(passWord)
}

6.驗證暱稱
class func validateNickname(nickname: String) -> Bool {
    var nicknameRegex = "^[\u{4e00}-\u{9fa5}]{4,8}$"
    var passWordPredicate = NSPredicate(format: "SELF MATCHES%@", nicknameRegex)
