Contrary to other available country picker libraries that store and use images of each country, DZCountryPicker tends to use the already available emoji images for each country by fetching the appropriate country codes. Because of this, the entire library boils down to two very simple files with no external dependencies.
It takes just one line of code to attach DZCountryPicker to a UITextField, and everything will be handled on its own. Currently the library only supports showing the countries list in a UIPickerView, but we're planning on supporting a drop-down UITableView and a presented UITableView in the future as well.
Simply drop in the DZCountryPicker folder into your XCode project (make sure to enable "Copy items if needed" and "Create groups").
CocoaPods is a dependency manager for Objective-C and Swift, which automates and simplifies the process of using 3rd-party libraries like LaunchDarkly in your projects. You can install it with the following command:
$ gem install cocoapods- To integrate LaunchDarkly into your Xcode project using CocoaPods, specify it in your
Podfile:
use_frameworks!
target 'YourTargetName' do
pod 'DZCountryPicker', '1.0.0'
end- Then, run the following command from the project directory that contains the podfile:
$ pod installTo attach DZCountryPicker to a UITextField, just create an object of the class, and assign it to the UITextField. The code might end up looking similar to the following.
@IBOutlet weak var countryField: UITextField!
let countryPicker = CountryPicker()
override func viewDidLoad() {
super.viewDidLoad()
countryPicker.textField = countryField
countryPicker.delegate = self
}To get the selected country you can either access the selectedCountry property of the object at any time.
DZCountryPicker also has a delegate method to inform when a country gets selected. You can use the following delegate method for that.
func didSelectCountry(country: Country) {
let name = country.name
let flag = country.flagEmoji
let code = country.phoneCode
}You can customize the text in the UIPickerView using the following properties.
countryPicker.textColor = UIColor.blue
countryPicker.font = UIFont.systemFont(ofSize: 17.0)Or directly access the CountryPicker object to modify other properties.
