I'm trying to create a calendar using JTAppleCalendar inside a xib view because I want a paging type thing for it. On the first page is some information, and the second page is the calendar. I followed the tutorials for JTAppleCalendar on multiple sites, but my project always crashes, probably because I'm doing something wrong.
I have 3 files, a DetailViewController for setting up and displaying the pages, a dataViewController to connect the xib vars, and a CollectionViewCell for the calendar cells.
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
}
}
And of course, the xib files. In DetailViewController, I moved the last extension part to dataViewController, but it didn't change anything. I'm also pretty sure I did many things wrong or inefficiently.
Can anyone help successfully implement the JTAppleCalendar inside the xib view, that would be appreciated! Thanks!
