CountryPickerView is a simple, customizable view for selecting countries in iOS apps.

You can clone/download the repository and run the demo project to see CountryPickerView in action. First run pod install from the CountryPickerViewDemo directory.

Note that 3.x releases are Swift 5 compatible. For the Swift 4 compatibility, use 2.x releases. For the Swift 3 compatibility, use 1.x releases.

Swift Package Manager is a dependency manager built into Xcode.

If you are using Xcode 11 or higher, go to File / Swift Packages / Add Package Dependency… and enter package repository URL https://github.com/kizitonwose/CountryPickerView.git then follow the instructions.

CountryPickerView is available through CocoaPods. Simply add the following to your Podfile:

use_frameworks!

target '<Your Target Name>' do
  pod 'CountryPickerView'
end

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

To install CountryPickerView through Carthage, simply add the following to your Cartfile:

github "kizitonwose/CountryPickerView"

1. Put CountryPickerView repo somewhere in your project directory.
2. In Xcode, add CountryPickerView.xcodeproj to your project.
3. On your app's target, add the CountryPickerView framework:
   1. as an embedded binary on the General tab.
   2. as a target dependency on the Build Phases tab.

If you're using Storyboards/Interface Builder you can create a CountryPickerView instance by adding a UIView to your Storyboard, and then manually changing the view's class to CountryPickerView in the "Custom Class" field of the Identity Inspector tab on the Utilities panel (the right-side panel)

You can also create an instance of CountryPickerView programmatically:

import CountryPickerView

let cpv = CountryPickerView(frame: /**Desired frame**/)

To get the selected country from your CountryPickerView instance at any time, use the selectedCountry property.

let country = cpv.selectedCountry
print(country)

This property is not optional, the default value is the user's current country, derived from the device's current Locale.

Customization options for the view itself are available directly via the CountryPickerView instance while options for the internal CountryPicker table view are available via the CountryPickerViewDataSource protocol. Setting the CountryPickerViewDelegate protocol is also necessary if you wish to be notified when the user selects a country from the list.

import CountryPickerView

class DemoViewController: UIViewController, CountryPickerViewDelegate, CountryPickerViewDataSource {

    @IBOutlet weak var countryPickerView: CountryPickerView!

    override func viewDidLoad() {
        super.viewDidLoad()

        countryPickerView.delegate = self
        countryPickerView.dataSource = self
    }
}

Note: The properties showCountryCodeInView and showCountryNameInView can't both be enabled at the same time. Enabling one to will disable the other. You can only show all properties on the list(see CountryPickerViewDataSource).

• Called when the user selects a country from the list or when you manually set the selectedCountry property of the CountryPickerView

  func countryPickerView(_ countryPickerView: CountryPickerView, didSelectCountry country: Country)

• Called before the CountryPickerViewController is presented or pushed. The CountryPickerViewController is a UITableViewController subclass.

  func countryPickerView(_ countryPickerView: CountryPickerView, willShow viewController: CountryPickerViewController)

• Called after the CountryPickerViewController is presented or pushed. The CountryPickerViewController is a UITableViewController subclass.

  func countryPickerView(_ countryPickerView: CountryPickerView, didShow viewController: CountryPickerViewController)

Note: If you already have a Country class or struct in your project then implementing the didSelectCountry delegate method can cause a compile error with a message saying that your conforming class does not comform to the CountryPickerViewDelegate protocol. This is because Xcode can't figure out which Country model to use in the method. The solution is to replace the Country in the method signature with the typealias CPVCountry, your delegate method should now look like this:

func countryPickerView(_ countryPickerView: CountryPickerView, didSelectCountry country: CPVCountry)

You can also use CPVCountry as a replacement for the framework's Country model in other parts of your project.

Also, willShow and didShow delegate methods are optional. If the CountryPickerViewController is presented(not pushed), it is embedded in a UINavigationController. The CountryPickerViewController class is made available so you can customize its appearance if needed. You can also access the public searchController(UISearchController) property in the CountryPickerViewController for customization.

The datasource methods define the internal(country list) ViewController's behavior. Run the demo project to play around with the options. All methods are optional.

• An array of countries you wish to show at the top of the list. This is useful if your app is targeted towards people in specific countries.

  func preferredCountries(in countryPickerView: CountryPickerView) -> [Country]

• The desired title for the preferred section.

  func sectionTitleForPreferredCountries(in countryPickerView: CountryPickerView) -> String?

  Note: You have to return a non-empty array of countries from preferredCountries(in countryPickerView: CountryPickerView) as well as this section title if you wish to show preferred countries on the list. Returning only the array or title will not work.

• Show ONLY the preferred countries section on the list. Default value is false

  func showOnlyPreferredSection(in countryPickerView: CountryPickerView) -> Bool

  Return true to hide the internal list so your users can only choose from the preferred countries list.

• The desired font for the section title labels on the list. Can be used to configure the text size.

  func sectionTitleLabelFont(in countryPickerView: CountryPickerView) -> UIFont

• The desired text color for the section title labels on the list.

  func sectionTitleLabelColor(in countryPickerView: CountryPickerView) -> UIColor?

• The desired font for the cell labels on the list. Can be used to configure the text size.

  func cellLabelFont(in countryPickerView: CountryPickerView) -> UIFont

• The desired text color for the country names on the list.

  func cellLabelColor(in countryPickerView: CountryPickerView) -> UIColor?

• The desired size for the flag images on the list.

  func cellImageViewSize(in countryPickerView: CountryPickerView) -> CGSize

• The desired corner radius for the flag images on the list.

  func cellImageViewCornerRadius(in countryPickerView: CountryPickerView) -> CGFloat

• The navigation item title when the internal view controller is pushed/presented. Default value is nil

  func navigationTitle(in countryPickerView: CountryPickerView) -> String?

• A navigation item button to be used if the internal view controller is presented(not pushed). If nil is returned, a default "Close" button is used. This method only enables you return a button customized the way you want. Default value is nil

  func closeButtonNavigationItem(in countryPickerView: CountryPickerView) -> UIBarButtonItem?

  Note: Any target or action associated with this button will be replaced as this button's sole purpose is to close the internal view controller.

• Desired position for the search bar. Default value is .tableViewHeader

  func searchBarPosition(in countryPickerView: CountryPickerView) -> SearchBarPosition

  Possible values are: .tableViewHeader, .navigationBar and .hidden

• Show the phone code alongside the country name on the list. e.g Nigeria ( 234). Default value is false

  func showPhoneCodeInList(in countryPickerView: CountryPickerView) -> Bool

• Show the country code alongside the country name on the list. e.g Nigeria (NG). If true, searches are also performed against the country codes. Default value is false

  func showCountryCodeInList(in countryPickerView: CountryPickerView) -> Bool

• Show a checkmark on the selected country on the list. Default value is true

  func showCheckmarkInList(in countryPickerView: CountryPickerView) -> Bool

• The locale used to display country names on the list. Default value is the current locale.

  func localeForCountryNameInList(in countryPickerView: CountryPickerView) -> Locale

A good use case for CountryPickerView is when used as the left view of a phone number input field.

class DemoViewController: UIViewController {

    @IBOutlet weak var phoneNumberField: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()

        let cpv = CountryPickerView(frame: CGRect(x: 0, y: 0, width: 120, height: 20))
        phoneNumberField.leftView = cpv
        phoneNumberField.leftViewMode = .always
    }
}

This means your users do not have to worry about entering the country's phone code in the text field. This also ensures you get a valid phone code from CountryPickerView instead of relying on your users.

If for any reason you do not want to show the default view or have your own implementation for showing country information, you can still use the internal picker to allow your users select countries from the list by calling the method showCountriesList(from: UIViewController) on a CountryPickerView instance.

It's important to keep a field reference to the CountryPickerView instance else it will be garbage collected and any attempt to use it will result to a crash.

class DemoViewController: UIViewController {

    // Keep a field reference
    let countryPickerView = CountryPickerView()

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    @IBAction func buttonPressed(_ sender: Any) {
        countryPickerView.showCountriesList(from: self)
    }
}

In the example above, calling countryPickerView.showCountriesList(from: self) will result in the internal picker view controller being presented in its own navigation stack because DemoViewController is not a navigation controller.

If you already have a navigation stack, you can push the internal picker view controller onto that stack by calling countryPickerView.showCountriesList(from: self.navigationController!) or do it the safe way:

if let nav = self.navigationController {
	countryPickerView.showCountriesList(from: nav)
}

Don't forget to set a delegate to be notified when the use selects a country from the list. An example of how to use the internal picker view controller is included in the demo project.

You can create Country instances with any of these methods in CountryPickerView class:

let countryPickerView = CountryPickerView()
let country = countryPickerView.getCountryByName("Nigeria")
let country2 = countryPickerView.getCountryByCode("NG")
let country3 = countryPickerView.getCountryByPhoneCode(" 234")

You can also set the selected country using these helper methods:

let countryPickerView = CountryPickerView()
countryPickerView.setCountryByName("Nigeria")
countryPickerView.setCountryByCode("NG")
countryPickerView.setCountryByPhoneCode(" 234")
