  1. Open your Xcode project.
  2. Go to “File” -> “Swift Packages” -> “Add Package Dependency”.
  3. Enter the URL of the repository: https://github.com/[repository_url].
  4. Select the version range or specific version you want to use.
  5. Click “Next” and wait for Xcode to download and integrate the package.

Usage

To use the AFHorizontalDayPicker in your project, follow these steps:

Step 1: Import the Library

In your Swift file, import the library by adding the following line at the top:

// Import AFHorizontalDayPicker
import AFHorizontalDayPicker

Step 2: Instantiate the AFHorizontalDayPicker

Create an instance of AFHorizontalDayPicker in your code:

let horizontalDayPicker = AFHorizontalDayPicker(frame: CGRect(x: 0, y: 0, width: 300, height: 60))

Step 3: Set Delegate and Data Source

Set the delegate and data source of the AFHorizontalDayPicker to your view controller:

horizontalDayPicker.delegate = self
horizontalDayPicker.dataSource = self

Step 4: Implement Delegate and Data Source Methods

In your view controller, implement the delegate and data source methods to customize the behavior and appearance of the AFHorizontalDayPicker:

  • func numberOfDays(in horizontalDayPicker: AFHorizontalDayPicker) -> Int: Return the number of days you want to display in the horizontal day picker.
  • func horizontalDayPicker(_ horizontalDayPicker: AFHorizontalDayPicker, titleForDayAt index: Int) -> String: Return the title for the day at the specified index.
  • func horizontalDayPicker(_ horizontalDayPicker: AFHorizontalDayPicker, didSelectDayAt index: Int): Handle the selection of a day in the horizontal day picker.

Step 5: Add the AFHorizontalDayPicker to Your View

Add the AFHorizontalDayPicker instance to your view hierarchy:

view.addSubview(horizontalDayPicker)

Example

Here’s an example of how to use the AFHorizontalDayPicker in your project:

// Import AFHorizontalDayPicker
import AFHorizontalDayPicker

class ViewController: UIViewController, AFHorizontalDayPickerDelegate, AFHorizontalDayPickerDataSource {

override func viewDidLoad() {
super.viewDidLoad()

// Create an instance of AFHorizontalDayPicker
let horizontalDayPicker = AFHorizontalDayPicker(frame: CGRect(x: 0, y: 0, width: 300, height: 60))

// Set the delegate and data source
horizontalDayPicker.delegate = self
horizontalDayPicker.dataSource = self

// Add the AFHorizontalDayPicker to your view
view.addSubview(horizontalDayPicker)
}

// MARK: - AFHorizontalDayPickerDataSource

func numberOfDays(in horizontalDayPicker: AFHorizontalDayPicker) -> Int {
return 7 // Display 7 days
}

func horizontalDayPicker(_ horizontalDayPicker: AFHorizontalDayPicker, titleForDayAt index: Int) -> String {
// Return the title for each day
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEEE" // Display full weekday names
let today = Date()
let offset = TimeInterval(60 * 60 * 24 * index) // Increment the date by 1 day for each index
let day = today.addingTimeInterval(offset)
return dateFormatter.string(from: day)
}

// MARK: - AFHorizontalDayPickerDelegate

func horizontalDayPicker(_ horizontalDayPicker: AFHorizontalDayPicker, didSelectDayAt index: Int) {
// Handle the selection of a day
let selectedDay = horizontalDayPicker.titleForDay(at: index)
print("Selected day:", selectedDay)
}
}
