🗺 Usage

You can instantiate it in storyboards/xibs or programmatically:

let phoneNumberTextField = FPNTextField(frame: CGRect(x: 0, y: 0, width: view.bounds.width - 16, height: 50))

// You can change the chosen flag then set the phone number
phoneNumberTextField.setFlag(for: .FR)
phoneNumberTextField.set(phoneNumber: "0600000001")

// Or directly set the phone number with country code, which will update automatically the flag image
phoneNumberTextField.set(phoneNumber: "[phone]")

🚨 FPNTextFieldDelegate

FPNTextFieldDelegate inherites from UITextFieldDelegate so nothing change:

phoneNumberTextField.delegate = self

It provides you three methods:

extension YourViewController: FPNTextFieldDelegate {

   /// The place to present/push the listController if you choosen displayMode = .list
   func fpnDisplayCountryList() {
      let navigationViewController = UINavigationController(rootViewController: listController)
      
      present(navigationViewController, animated: true, completion: nil)
   }

   /// Lets you know when a country is selected 
   func fpnDidSelectCountry(name: String, dialCode: String, code: String) {
      print(name, dialCode, code) // Output "France", "+33", "FR"
   }

   /// Lets you know when the phone number is valid or not. Once a phone number is valid, you can get it in severals formats (E164, International, National, RFC3966)
   func fpnDidValidatePhoneNumber(textField: FPNTextField, isValid: Bool) {
      if isValid {
         // Do something...         
         textField.getFormattedPhoneNumber(format: .E164),           // Output "[phone]"
         textField.getFormattedPhoneNumber(format: .International),  // Output "[phone]"
         textField.getFormattedPhoneNumber(format: .National),       // Output "06 00 00 00 01"
         textField.getFormattedPhoneNumber(format: .RFC3966),        // Output "tel:[phone]"
         textField.getRawPhoneNumber()                               // Output "600000001"
      } else {
         // Do something...
      }
   }
}

🎨 Customization

By default, the picker view is showed but you can display the countries with a list view controller:

var listController: FPNCountryListViewController = FPNCountryListViewController(style: .grouped)

phoneNumberTextField.displayMode = .list // .picker by default

listController.setup(repository: textField.countryRepository)
listController.didSelect = { [weak self] country in
self?.textField.setFlag(countryCode: country.code)

Don't forget to implement the fpnDisplayCountryList:

func fpnDisplayCountryList() {
   let navigationViewController = UINavigationController(rootViewController: listController)

   listController.title = "Countries"

   self.present(navigationViewController, animated: true, completion: nil)
}

FlagKit is used by default but you can customize the list with your own flag icons assets:

// Be sure to set it before initializing a FlagPhoneNumber instance.
Bundle.FlagIcons = YOUR_FLAG_ICONS_BUNDLE

You can change the size of the flag button:

phoneNumberTextField.flagButtonSize = CGSize(width: 44, height: 44)

You can customize the inputAccessoryView of the textfield:

phoneNumberTextField.textFieldInputAccessoryView = getCustomTextFieldInputAccessoryView(with: items)

You can also customize the flag button's properties:

// This will freeze the flag.
// Only one particular country's phone numbers will be formatted and validated.
// You can set the country by setting the flag as shown earlier.
phoneNumberTextField.flagButton.isUserInteractionEnabled = false

You can have in the placeholder an example of a phone number according to the selected country or have your own placeholder:

phoneNumberTextField.hasPhoneNumberExample = false // true by default
phoneNumberTextField.placeholder = "Phone Number"

You can choose which country can appears in the list:

phoneNumberTextField.setCountries(including: [.FR, .ES, .IT, .BE, .LU, .DE])

Or exclude countries from the list:

phoneNumberTextField.setCountries(excluding: [.AM, .BW, .BA])

You can choose to display the country phone code in the picker or in the list view controller:

phoneNumberTextField.pickerView.showCountryPhoneCode = false // true by default
listController.showCountryPhoneCode = false // true by default

You can reuses FPN classes as you see fit !
