3 years ago Hi, Thank you for using CalendarHeatmap framework. Hope you find it useful.
The thing is currently we don’t support auto refresh functionality. If the data source changed you have to call the reload function to make the UI update, more like the UITableView reload.
Hope this helps.

Hi, I'm a newbie developer and using SwiftUI for interface development.
So I managed to embed your framework into the SwiftUI and using the custom data function for the heatmap data. `import SwiftUI import UIKit import CalendarHeatmap
struct HeatMapView: UIViewControllerRepresentable { var startDate: Date var endDate: Date var heatMapData: [String : Int]?
func makeUIViewController(context: Context) -> UIViewController {
let uiView = ViewController(startDate: startDate, endDate: endDate, heatMapData: heatMapData) return uiView}
func updateUIViewController(_ uiViewController: UIViewController, context: Context) {
}
}
struct HeatMapView_Previews: PreviewProvider { static var previews: some View { let url = Bundle.main.url(forResource: "heatmap", withExtension: "plist") HeatMapView(startDate: Date(2019, 1, 20), endDate: Date(2020, 3, 25), heatMapData: NSDictionary(contentsOf: url!) as? [String: Int]) .environment(.colorScheme, .dark) } }
class ViewController: UIViewController {
public var startDate: Date
public var endDate: Date
public var heatMapData: [String : Int]?
public init(startDate: Date, endDate: Date, heatMapData: [String : Int]?) {
self.startDate = startDate self.endDate = endDate self.heatMapData = heatMapData super.init(nibName: nil, bundle: nil)}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")}
lazy var data: [String: UIColor] = {
guard let data = heatMapData else { return [:] } return data.mapValues { (colorIndex) -> UIColor in switch colorIndex { case 0..<500: return UIColor(Color.accentColor.opacity(0.2)) case 500..<2000: return UIColor(Color.accentColor.opacity(0.4)) case 2000..<6000: return UIColor(Color.accentColor.opacity(0.6)) case 6000..<8000: return UIColor(Color.accentColor.opacity(0.8)) case 8000...: return UIColor(Color.accentColor) default: return UIColor(Color(.systemGray5).opacity(0.5)) } }}()
lazy var calendarHeatMap: CalendarHeatmap = {
var config = CalendarHeatmapConfig() config.backgroundColor = .systemBackground // config item config.allowItemSelection = false config.itemSide = 15 config.contentRightInset = 10 // config month header config.monthHeight = 30 config.monthStrings = ["1月", "2月", "3月", "4月", "5月", "6月", "7月", "8月", "9月", "10月", "11月", "12月"] config.monthFont = UIFont.systemFont(ofSize: 11) config.monthColor = UIColor(Color.primary.opacity(0.3)) // config weekday label on left config.weekDayFont = UIFont.systemFont(ofSize: 10) config.weekDayStrings = ["日", "一", " ", "三", " ", "五", " "] config.weekDayStandard = .International config.weekDayWidth = 20 config.weekDayColor = UIColor(Color.primary.opacity(0.3)) let calendar = CalendarHeatmap(config: config, startDate: startDate, endDate: endDate) calendar.delegate = self return calendar}()
override func viewDidLoad() {
super.viewDidLoad() view.backgroundColor = .systemBackground view.addSubview(calendarHeatMap) calendarHeatMap.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ calendarHeatMap.leftAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leftAnchor, constant: 0), calendarHeatMap.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: 12), calendarHeatMap.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 5) ])}
} ` Everything works great but when the heatmap data changed, the heatmap view doesn't update automatically - unless I close and reopen the page again. I've searched and tried everything I can, but none of those works. Could you please give me some advice on this, or there is already a solution for this but I'm using it in the wrong way?
Thanks!
