Xcode Radio Button Example – Creating Radio Button using Swift

Radio Button is a very common component of any application. It allows us to choose only one option among a set of options. So in this Xcode Radio Button Example we will be learning how to use Radio Button while creating iOS Apps using Swift.

Xcode Radio Button Example

Creating a new Xcode Project

• As always we do we will create a new Xcode Project. I am creating a new Single View Application.

Adding DLRadio Buttons to the Project

• The problem is Xcode does not have any inbuilt option for creating Radio Buttons. So I am going to use this DLRadio Button Library I found in GitHub.
• So Open Terminal and navigate to your Project Directory.
• Now run the following command.

pod init

• Now this will create a file named podfile in your project directory.
• Open the file with any code editor (I am using Sublime) and replace the whole code of the file with the following.

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'RadioButtonExample' do

  pod 'DLRadioButton', '~> 1.4'

end

• Now save the file and again come inside terminal and run the following command.

pod install

• And you will see the following results.

• Now close Xcode and open YourProjectName.xcworkspace. You will find it inside your project directory.
• If you are confused about these steps then see Xcode Firebase Tutorial where I explained using CocoaPods in very detail.

Creating Radio Buttons

• Now to create Radio Buttons we will create UIButton.
• But first we will Drag Drop a View to our Storyboard. This is to group our Radio Buttons.

• Now Drag two Buttons inside the View. And also drag a Label.
• Change the Button type to Custom in Attribute Inspector.

• Now come to Identity Inspector and change the custom class to DLRadioButton.

• So by now you will see the following screen in your storyboard.

• Now you can test your Radio Buttons. But right now it will not behave as a Radio Button. If you will be able to select both options as shown in the image.

• Now secondary click on your first radio button. And inside Outlet Collections drag otherButtons to the second Radio button (Female). If you have more radio button then you have to do the same for every button.

• Now if you will run the application in Simulator you will see only one button is selecting.

Handling Radio Button Clicks

• This process is same as we learnt in Xcode Button Tutorial. Just connect your Views to your Swift code. And then you can handle Option Selection as I did in the following code.

import UIKit
import DLRadioButton

class ViewController: UIViewController {

    @IBOutlet weak var label: UILabel!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    
    @IBAction func radioMale(sender: AnyObject) {
        label.text = "Gender is Male"
    }
    
    
    @IBAction func radioFemale(sender: AnyObject) {
        label.text = "Gender is Female"
    }

}

• Now run your application and you will see the following output.

• Bingo! Its working absolutely fine. Now if you need you can get my source code from the below link.
