在xib视图中创建JTAppleCalendar

Question

我试图在xib视图中使用JTAppleCalendar创建一个日历，因为我希望它有一个分页类型。第一页是一些信息，第二页是日历。我在多个站点上学习了JTAppleCalendar的教程，但我的项目总是崩溃，可能是因为我做错了什么。

我有3个文件，一个用于设置和显示页面的DetailViewController，一个连接xib的dataViewController，以及一个用于日历单元格的CollectionViewCell。

DetailViewController

import UIKit
import JTAppleCalendar

class DetailViewController: UIViewController {

    var sportName: String = ""
    var numClasses: Int = 0

    var pages : [dataViewController]{
        get {
            let page1: dataViewController = Bundle.main.loadNibNamed("dataView", owner: self, options: nil)?.first as! dataViewController
            page1.label.text = sportName
            page1.classDuration.text = String(numClasses)

            let page2: dataViewController = Bundle.main.loadNibNamed("secondDataView", owner: self, options: nil)?.first as! dataViewController
            page2.calendar.calendarDataSource = self as? JTACMonthViewDataSource
            page2.calendar.calendarDelegate = self as? JTACMonthViewDelegate
            page2.calendar.reloadData()


            return [page1, page2]
        }
    }

    @IBOutlet weak var detailDescriptionLabel: UILabel!
    @IBOutlet weak var scrollView: UIScrollView!
    @IBOutlet weak var pageControl: UIPageControl!


    func configureView() {
        // Update the user interface for the detail item.
        if let detail = detailItem {
            if let label = detailDescriptionLabel {
                label.text = detail.description
            }
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

        let back = UIBarButtonItem(title: "Back",style: .plain,target: self,action: #selector(backButton(_:)))
        self.navigationItem.leftBarButtonItem = back

        configureView()
        view.bringSubviewToFront(pageControl)
        setupScrollView(pages: pages)

        pageControl.numberOfPages = pages.count
        pageControl.currentPage = 0



    }

    var detailItem: String? {
        didSet {
            // Update the view.
            configureView()
        }
    }

    @objc
    func backButton (_ sender: Any) {
        performSegue(withIdentifier: "detailToList", sender: self)
    }

    func setupScrollView(pages: [dataViewController]){
        scrollView.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: view.frame.height)
        scrollView.contentSize = CGSize(width: view.frame.width * CGFloat(pages.count), height: view.frame.height)
        scrollView.isPagingEnabled = true

        for i in 0 ..< pages.count {
            pages[i].frame = CGRect(x: view.frame.width * (CGFloat(i)), y: 0, width: view.frame.width, height: view.frame.height)
            scrollView.addSubview(pages[i])
        }
    }


}

extension DetailViewController: UIScrollViewDelegate {

    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        let pageIndex = round(scrollView.contentOffset.x/view.frame.width)
        pageControl.currentPage = Int(pageIndex)
    }

}

extension dataViewController: JTACMonthViewDataSource, JTACMonthViewDelegate {

    func configureCalendar(_ calendar: JTACMonthView) -> ConfigurationParameters {
        let formatter = DateFormatter()
        formatter.dateFormat = "yyyy MM dd"
        formatter.timeZone = Calendar.current.timeZone
        formatter.locale = Calendar.current.locale
        let startDate = formatter.date(from: "2020 01 01")!
        let endDate = Date()
        return ConfigurationParameters(startDate: startDate, endDate: endDate)
    }

    func calendar(_ calendar: JTACMonthView, cellForItemAt date: Date, cellState: CellState, indexPath: IndexPath) -> JTACDayCell {
        let cell = calendar.dequeueReusableJTAppleCell(withReuseIdentifier: "dateCell", for: indexPath) as! CollectionViewCell
        cell.dateLabel.text = cellState.text
        return cell
    }

    func calendar(_ calendar: JTACMonthView, willDisplay cell: JTACDayCell, forItemAt date: Date, cellState: CellState, indexPath: IndexPath) {
        let cell = cell as! CollectionViewCell
        cell.dateLabel.text = cellState.text
    }

}

dataViewController

import JTAppleCalendar

class dataViewController: UIView {
//Page 1
    @IBOutlet weak var label: UILabel!
    @IBOutlet weak var classDuration: UILabel!

//Page 2

    @IBOutlet weak var calendar: JTACMonthView!

}

CollectionViewCell

import UIKit
import JTAppleCalendar

class CollectionViewCell: JTACDayCell {

    @IBOutlet weak var dateLabel: UILabel!

    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

}

当然，xib文件。在DetailViewController中，我将最后一个扩展部分移到了dataViewController，但是它没有改变任何东西。我也很肯定我做了很多错事或低效的事情。

有谁能帮助在xib视图中成功地实现JTAppleCalendar，这将是非常感谢的！谢谢!

Answer 1

在您的DetailViewController中，您正在将日历的委托和dataSource设置为self，这不符合这些协议。

page2.calendar.calendarDataSource = self as? JTACMonthViewDataSource
page2.calendar.calendarDelegate = self as? JTACMonthViewDelegate

如果需要在DetailViewController中处理thoose，我建议您从DetailViewController而不是dataViewController中的实现方法开始。

extension DetailViewController: JTACMonthViewDataSource, JTACMonthViewDelegate
