Swift 中的邮箱和电话验证

是的，您的错误在下面的XCode 6.1中

发生此错误是因为if条件必须返回Bool类型，但在if条件中返回类型为NSPredicate，因此得到错误swift: Bound value in a conditional binding must be of Optional type，可以按如下方式解决.

    var phoneTest = NSPredicate(format: "SELF MATCHES %@", PHONE_REGEX)
         if phoneTest.evaluateWithObject(value) {
                  return (true, .NoError)
             }
                 return (false, .PhoneNumber)
            }

Email-Validations in Swift.

    func isValidEmail(testStr:String) -> Bool {
            print("validate emilId: \(testStr)")
            let emailRegEx = "^(?:(?:(?:(?: )*(?:(?:(?:\\t| )*\\r\\n)?(?:\\t| )+))+(?: )*)|(?: )+)?(?:(?:(?:[-A-Za-z0-9!#$%&’*+/=?^_'{|}~]+(?:\\.[-A-Za-z0-9!#$%&’*+/=?^_'{|}~]+)*)|(?:\"(?:(?:(?:(?: )*(?:(?:[!#-Z^-~]|\\[|\\])|(?:\\\\(?:\\t|[ -~]))))+(?: )*)|(?: )+)\"))(?:@)(?:(?:(?:[A-Za-z0-9](?:[-A-Za-z0-9]{0,61}[A-Za-z0-9])?)(?:\\.[A-Za-z0-9](?:[-A-Za-z0-9]{0,61}[A-Za-z0-9])?)*)|(?:\\[(?:(?:(?:(?:(?:[0-9]|(?:[1-9][0-9])|(?:1[0-9][0-9])|(?:2[0-4][0-9])|(?:25[0-5]))\\.){3}(?:[0-9]|(?:[1-9][0-9])|(?:1[0-9][0-9])|(?:2[0-4][0-9])|(?:25[0-5]))))|(?:(?:(?: )*[!-Z^-~])*(?: )*)|(?:[Vv][0-9A-Fa-f]+\\.[-A-Za-z0-9._~!$&'()*+,;=:]+))\\])))(?:(?:(?:(?: )*(?:(?:(?:\\t| )*\\r\\n)?(?:\\t| )+))+(?: )*)|(?: )+)?$"
            let emailTest = NSPredicate(format:"SELF MATCHES %@", emailRegEx)
            let result = emailTest.evaluateWithObject(testStr)
            return result
        } 

邮箱验证的使用:

    if isValidEmail("kirit@gmail.com"){
            print("Validate EmailID")
        }
        else{
            print("invalide EmailID")
        }

Phone-Number Validation in Swift

            let PHONE_REGEX = "^\\d{3}-\\d{3}-\\d{4}$"
            let phoneTest = NSPredicate(format: "SELF MATCHES %@", PHONE_REGEX)
            let result = phoneTest.evaluate(with: value)
            return result
        }
