YMValidator

TextField Validation library for Swift (@IBDesignable & Programmatically)

Documentation

Usage

First create your custom validator class. The class has to have @objc declaration, conform to YMRulesValidator protocol and NSObject .

@objc(EmailValidator)
class EmailValidator: NSObject, YMRulesValidator {
  var regex: String = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,}"
}

With Storyboard

1. Add your TextField
2. Set the custom class YMValidator
3. On attributs inspector, set Class Name and Error Message

4. Set the error label to YMValidator

@IBOutlet weak var errorEmailLabel: UILabel!
@IBOutlet weak var inputEmail: YMValidator!

override func viewDidLoad() {
    super.viewDidLoad()
    self.errorEmailLabel.text = ""    
    self.inputEmail.setErrorLabel(self.errorEmailLabel)
}

Programmatically

//ViewController.swift
let textField = YMValidator(frame: CGRect(x: 30.0, y: 296.0, width: 540, height: 30), rulesValidator: CustomValidator(), errorMessage: "Only alphanumeric characters are allowed", errorLabel: customErrorLabel)
self.view.addSubview(textField)

Finally

You can check if all inputs are valid with this static function.

YMValidator.areValid(self)
