How to detect the country code and change flag in FPNTextField - ios

Question

I am using FlagPhoneno Pod to search or select country codes with flags, by using below codes. But when comes to edit part I get full phone no to the FPNtextFeild ex- [phone] and by default i set country code as .AE
I want to detect and automatically change the country flag when any other country phone no fetch from json let recivedPhoneNo = self.json["phone_number"].string ?? ""
For the moment the flag is changing when select only. please show me an example method with code from same pod "FlagPhoneno" module.
I am using following code.
func setupPhoneTF(){
self.phoneTFView.layer.borderColor = UIColor.appColor.customGray.cgColor
self.phoneTFView.layer.cornerRadius = 5
self.phoneTFView.layer.borderWidth = 1
phoneTF.displayMode = .list // .picker by default
listController.setup(repository: phoneTF.countryRepository)
listController.didSelect = { [weak self] country in
self?.phoneTF.setFlag(countryCode: country.code)
}
phoneTF.delegate = self
phoneTF.font = UIFont.systemFont(ofSize: 14)
// Custom the size/edgeInsets of the flag button
phoneTF.flagButtonSize = CGSize(width: 35, height: 35)
phoneTF.flagButton.imageEdgeInsets = UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 10)
let items = [
UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.save, target: self, action: nil),
UIBarButtonItem(title: "Item 1", style: .plain, target: self, action: nil),
UIBarButtonItem(title: "Item 2", style: .plain, target: self, action: nil)
]
phoneTF.textFieldInputAccessoryView = getCustomTextFieldInputAccessoryView(with: items)
phoneTF.hasPhoneNumberExample = true
phoneTF.placeholder = "Phone Number"
phoneTF.setFlag(countryCode: .AE)
}
extension AddNewAddressVC: FPNTextFieldDelegate {
func fpnDidValidatePhoneNumber(textField: FPNTextField, isValid: Bool) {
textField.rightViewMode = .whileEditing
textField.rightView = UIImageView(image: isValid ? imageLiteral(resourceName: "success") : imageLiteral(resourceName: "error"))
print(
isValid,
textField.getFormattedPhoneNumber(format: .E164) ?? "E164: nil",
textField.getFormattedPhoneNumber(format: .International) ?? "International: nil",
textField.getFormattedPhoneNumber(format: .National) ?? "National: nil",
textField.getFormattedPhoneNumber(format: .RFC3966) ?? "RFC3966: nil",
textField.getRawPhoneNumber() ?? "Raw: nil"
)
}
func fpnDidSelectCountry(name: String, dialCode: String, code: String) {
print(name, dialCode, code)
self.selectedDialCod = dialCode
}
func fpnDisplayCountryList() {
let navigationViewController = UINavigationController(rootViewController: listController)
listController.title = "Countries"
listController.navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .stop, target: self, action: #selector(dismissCountries))
self.present(navigationViewController, animated: true, completion: nil)
}
}

Answer 1

// 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]")

Answer 2

FlagPhoneNumber pod have an issue by which flag get disappear after upload and if you reinstall the ipa from testflight the flag will be gone.
