How to Manage Selected Buttons in a Swift UITableView

Are you developing an iOS app and struggling with managing button selections within a UITableView? If you’re using Swift and need a user-friendly way to track the selected answers from multiple cells, you’re in the right place. In this guide, we’ll walk you through how to ensure that buttons within your table view cells work correctly, so only one button can be selected at a time, and how to count the selections when it's time to take action.

Understanding the Problem

In your project, you are working with a table view consisting of several cells (in this case, five). Each cell presents a question with two buttons labeled “Yes” and “No”. When a user taps a button, it should change color to indicate that it’s selected, while the other button in the same cell should return to its default state. Moreover, you want to enable a continue button only when all questions have been answered.

Here's a quick breakdown of your main requirements:

Only one button (either "Yes" or "No") should be selected at any one time in each cell.

You need to count how many "Yes" and "No" answers have been selected when the continue button is pressed.

Implementing the Solution

Step 1: Create a Model for Your Questions

To efficiently manage the selection states of your buttons, it’s essential to use a data model. In Swift, you can create a struct to represent each question, which includes the text of the question and a property to track the selected answer:

Step 2: Updating Button Selections

When a user taps a button, you'll want to update the selectedAnswer property for that particular question. Here’s how you might do it within your cell configuration:

Detect Button Taps: Implement an action method for your buttons to update the selection state.

Change Background Color: Adjust the button colors accordingly.

Deselect Other Button: Ensure the other button in that particular cell is deselected.

Here’s a sample implementation:

Step 3: Counting Selections at Continue Button Action

Once a user has decided on all answers and clicks the continue button, you need to count how many "Yes" and "No" answers were made. For this, you can use the getAllAnswers() function from your Question struct:

Conclusion

By following the steps outlined in this guide, you will effectively manage button selections in your UITableView, ensuring only one button is selected at a time while also counting the responses correctly upon user confirmation. This not only enhances the user experience but also strengthens the functionality of your app.

Embrace these strategies in your development process, and you’ll find it much easier to track user selections within your table view cells! Happy coding!
