是否可以在Swift中使用JTAppleCalendar设置开始日期和结束日期？

import JTAppleCalendar

class ViewController: UIViewController {
    @IBOutlet weak var calendarView: JTAppleCalendarView!
    
    let formatter = DateFormatter()
    var startDate: Date?
    var endDate: Date?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        calendarView.delegate = self
        calendarView.dataSource = self
        
        // 设置日期格式
        formatter.dateFormat = "yyyy-MM-dd"
        
        // 设置开始日期和结束日期
        startDate = formatter.date(from: "2022-01-01")
        endDate = formatter.date(from: "2022-01-31")
        
        // 刷新日历视图
        calendarView.reloadData()
    }
}

extension ViewController: JTAppleCalendarViewDelegate, JTAppleCalendarViewDataSource {
    func configureCalendar(_ calendar: JTAppleCalendarView) -> ConfigurationParameters {
        let parameters = ConfigurationParameters(startDate: startDate!, endDate: endDate!)
        return parameters
    }
    
    func calendar(_ calendar: JTAppleCalendarView, cellForItemAt date: Date, cellState: CellState, indexPath: IndexPath) -> JTAppleCell {
        let cell = calendar.dequeueReusableJTAppleCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCell
        
        // 设置单元格的日期文本
        cell.dateLabel.text = cellState.text
        
        // 根据日期状态设置单元格的外观
        if cellState.dateBelongsTo == .thisMonth {
            cell.isHidden = false
        } else {
            cell.isHidden = true
        }
        
        return cell
    }
}
