Valide is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod "Valide"From your ViewController set up everything first. Start with the validation names for the fields.
struct ValidationNames {
static let nameField: String = "nameField"
static let emailField: String = "emailField"
static let nonEmptyField: String = "nonEmptyField"
}Set up the rules you need. (You can create your own rules as well). Fields can have multiple rules to adhere to.
let requiredRule = RequiredRule()
let emailRule = EmailRule()
let emptyFieldRule = NonEmptyFieldRule()
let minCharsRule = MinCharsRule()
minCharsRule.minChars = 3
let maxCharsRule = MaxCharsRule()
maxCharsRule.maxChars = 50Set validation name to field and add rules:
self.name.validationName = ValidationNames.nameField
self.name.addRule(requiredRule)
self.name.addRule(minCharsRule)
self.name.addRule(maxCharsRule)
self.emailField.validationName = ValidationNames.emailField
self.emailField.addRule(requiredRule)
self.emailField.addRule(emailRule)
self.nonEmptyField.validationName = ValidationNames.nonEmptyField
self.nonEmptyField.addRule(emptyFieldRule)
self.nonEmptyField.addRule(requiredRule)When handling validation, usually by pressing a button, call the validate() method. This returns a closure with a success and error.
Upon receiving an error, the name of the field is returned as well as the error defined in the *Rule file. These can also be customised to your liking.
self.name.validate({
print("namefield validates")
}, error: { (validationName, error) -> () in
print("\(validationName) handle: \(error)")
})
self.emailField.validate({
print("emailField validates")
}, error: { (validationName, error) -> () in
print("\(validationName) handle: \(error)")
})
self.nonEmptyField.validate({
print("nonEmptyField validates")
}, error: { (validationName, error) -> () in
print("\(validationName) handle: \(error)")
})For now; start with validating of the last element in your UI. So the last validation you code, is the first element on screen. I have not found a better way to do this. (If you do - please let me know)
You can then check the .isValid() on the field you are validating. This returns a tuple with three properties.
func isValid() -> (isValid:Bool, validationName: String, error: String?)So then you can check self.nonEmptyField.isValid().isValid property.
if self.nonEmptyField.isValid().isValid {
print("Field validates!")
// Do something...
