TextField 电话号码或电子邮件格式验证迅速吗？

Question

我有一个忘记密码的文本字段，在这里用户输入手机号码或电子邮件，然后我们发送 OTP。

我正在尝试使用我的代码验证该文本字段，但它不起作用，任何人对此有一些想法，请通过以下方式找到我的代码。

它需要对 mailid 或电话号码格式有效。

if emaiTF.text == "" {
            print("Enter either valid phone or email")
        }else if let validphone = emaiTF.text, validphone.isValidPhone() || validphone.isValidEmail() {
            print("Enter either valid phone or email")
        }else{
            forGotPasswordApi()
        }

我的验证方法如下。

extension String {
    func isValidEmail() -> Bool {
        // here, `try!` will always succeed because the pattern is valid
        let regex = try! NSRegularExpression(pattern: "^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$", options: .caseInsensitive)
        return regex.firstMatch(in: self, options: [], range: NSRange(location: 0, length: count)) != nil
    }

    // vrify Valid PhoneNumber or Not
    func isValidPhone() -> Bool {

        let phoneRegex = "^[0-9]{10}$";
        let valid = NSPredicate(format: "SELF MATCHES %@", phoneRegex).evaluate(with: phoneRegex)
        return valid
    }
}

这似乎是您的输出验证中的问题。修改了你的代码以如下方式工作，请验证。

  extension ViewController {

    func checkValidation() {
      if txtUserName.text == "" {
          print("Enter either valid phone or email 1")
      } else if let validphone = txtUserName.text, validphone.isValidPhone() || validphone.isValidEmail() {
          print("Success")
          forGotPasswordApi()
      }else{
        print("Enter either valid phone or email 2")
      }
    }
  }

  extension String {
      func isValidEmail() -> Bool {
          // here, `try!` will always succeed because the pattern is valid
          let regex = try! NSRegularExpression(pattern: "^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,3})$", options: .caseInsensitive)
        let valid = regex.firstMatch(in: self, options: [], range: NSRange(location: 0, length: count)) != nil
        print("Email validation \(valid)")
          return valid
      }

      // vrify Valid PhoneNumber or Not
      func isValidPhone() -> Bool {

        let regex = try! NSRegularExpression(pattern: "^[0-9]\\d{9}$", options: .caseInsensitive)
        let valid = regex.firstMatch(in: self, options: [], range: NSRange(location: 0, length: count)) != nil
        print("Mobile validation \(valid)")
          return valid
      }
  }

我的验证是：

extension String {

var isValidEmail: Bool {
    return NSPredicate(format: "SELF MATCHES %@", "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,3}").evaluate(with: self)
}
 var numberValidation: Bool {
    return NSPredicate(format: "SELF MATCHES %@", "^(?=.*[0-9]).{10}$").evaluate(with: self)
  }
}

我用于检查输入的代码

if mailTextField.text!.isValidEmail {
        print("u have entered correct mail format")
    }
if phonenumber.text!.numberValidation {
 print("mobile number in correct format")
}

电话号码验证

 func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {

    let aSet = NSCharacterSet(charactersIn:"0123456789").inverted

    let compSepByCharInSet = string.components(separatedBy: aSet)

    let numberFiltered = compSepByCharInSet.joined(separator: "")

    guard let text = textField.text else { return true }

    let count = text.count + string.count - range.length

    return string == numberFiltered && count <= 10

  }

Answer 4

我通过更改验证检查稍微更新了您提供的代码。我认为 validInput.isValidPhone() || validInput.isValidEmail() 没有在您的代码上正确处理。

// Check if any input is entered and not empty string
guard let validInput = emaiTF.text, validInput != "" else {
  print("Enter either valid phone or email")
  return
}

// Check if entered value is valid or not
if validInput.isValidPhone() || validInput.isValidEmail() { 
  forGotPasswordApi()
} else {
  print("Enter either valid phone or email")
}

电子邮件验证

在下面的方法中传递你的字符串

以下方法将返回布尔值 YES 或 NO

方法：

 func isValidEmail(testStr:String) -> Bool {
    // print("validate calendar: \(testStr)")
    let emailRegEx = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"

    let emailTest = NSPredicate(format:"SELF MATCHES %@", emailRegEx)
    return emailTest.evaluate(with: testStr)
}

用法：

if isValidEmail(testStr: emailTxtFld.text!) == True {

       print("Valid");        
 }
else {

    print("In Valid");
 }
