I am making an attempt to implement CalendarKit utilizing SwiftUI’s UIViewControllerRepresentable. The instance offered by the library is in UIKit. I’ve efficiently displayed the UI, however when I attempt to go dummy occasions knowledge to show occasions in CalendarKit, the DayViewDelegate and EventDataSource strategies contained in the coordinator class will not be being referred to as, and no knowledge is being displayed.
What am I doing mistaken, or how can I obtain this? Any sort of assist can be appreciated.
My SwiftUI Representable Code:
import SwiftUI
import CalendarKit
struct DayViewControllerWrapper: UIViewControllerRepresentable {
@Binding var selectedEvent: Occasion?
@Binding var occasions: [EventDescriptor]
// Callbacks for coordinator delegates
var didSelectEventView: ((EventView) -> Void)?
var didLongPressEventView: ((EventView) -> Void)?
var didTapTimelineAt: ((Date) -> Void)?
var didLongPressTimelineAt: ((Date) -> Void)?
var didBeginDragging: (() -> Void)?
var didTransitionCancel: (() -> Void)?
var willMoveTo: ((Date) -> Void)?
var didMoveTo: ((Date) -> Void)?
var didUpdateEvent: ((EventDescriptor) -> Void)?
func makeUIViewController(context: Context) -> DayViewController {
let viewController = DayViewController()
// Arrange bindings for delegates and knowledge sources
viewController.dataSource = context.coordinator
viewController.delegate = context.coordinator
return viewController
}
func updateUIViewController(_ uiViewController: DayViewController, context: Context) {
uiViewController.reloadData()
}
func makeCoordinator() -> Coordinator {
return Coordinator(self)
}
class Coordinator: NSObject, EventDataSource, DayViewDelegate {
var father or mother: DayViewControllerWrapper
init(_ father or mother: DayViewControllerWrapper) {
self.father or mother = father or mother
}
// MARK: - EventDataSource
func eventsForDate(_ date: Date) -> [EventDescriptor] {
return father or mother.occasions
}
// MARK: - DayViewDelegate
func dayViewDidSelectEventView(_ eventView: EventView) {
father or mother.selectedEvent = eventView.descriptor as? Occasion
father or mother.didSelectEventView?(eventView)
}
func dayViewDidLongPressEventView(_ eventView: EventView) {
father or mother.didLongPressEventView?(eventView)
}
func dayView(dayView: DayView, didTapTimelineAt date: Date) {
father or mother.didTapTimelineAt?(date)
}
func dayView(dayView: DayView, didLongPressTimelineAt date: Date) {
father or mother.didLongPressTimelineAt?(date)
}
func dayViewDidBeginDragging(dayView: DayView) {
father or mother.didBeginDragging?()
}
func dayViewDidTransitionCancel(dayView: DayView) {
father or mother.didTransitionCancel?()
}
func dayView(dayView: DayView, willMoveTo date: Date) {
father or mother.willMoveTo?(date)
}
func dayView(dayView: DayView, didMoveTo date: Date) {
father or mother.didMoveTo?(date)
}
func dayView(dayView: DayView, didUpdate occasion: EventDescriptor) {
father or mother.didUpdateEvent?(occasion)
}
}
}
struct DayViewControllerWrapper_Previews: PreviewProvider {
static var previews: some View {
DayViewControllerWrapper(selectedEvent: .fixed(nil), occasions: .fixed([]))
}
}
My ContentView code, how i am utilizing it.
import SwiftUI
import CalendarKit
struct ContentView: View {
@State personal var selectedEvent: Occasion?
@State personal var occasions: [EventDescriptor] = []
var physique: some View {
VStack {
Textual content("My Customized Calendar Instance")
DayViewControllerWrapper(
selectedEvent: $selectedEvent,
occasions: $occasions,
didSelectEventView: { eventView in
// Deal with occasion choice
print("Chosen occasion: (eventView.descriptor)")
},
didLongPressEventView: { eventView in
// Deal with lengthy press occasion
print("Lengthy pressed occasion: (eventView.descriptor)")
},
didTapTimelineAt: { date in
// Deal with faucet on timeline
print("Tapped timeline at: (date)")
},
didLongPressTimelineAt: { date in
// Deal with lengthy press on timeline
print("Lengthy pressed timeline at: (date)")
},
didBeginDragging: {
// Deal with start dragging
print("Started dragging")
},
didTransitionCancel: {
// Deal with transition cancel
print("Transition canceled")
},
willMoveTo: { date in
// Deal with will transfer thus far
print("Will transfer thus far: (date)")
},
didMoveTo: { date in
// Deal with did transfer thus far
print("Did transfer thus far: (date)")
},
didUpdateEvent: { occasion in
// Deal with updating occasion
print("Up to date occasion: (occasion)")
}
)
.body(top: 400) // Alter body top as wanted
.onAppear {
// Populate occasions with dummy knowledge
generateDummyData()
}
}
}
personal func generateDummyData() {
occasions = [
createEvent(title: "Breakfast at Tiffany's", location: "New York, 5th avenue"),
createEvent(title: "Workout", location: "Tufteparken"),
createEvent(title: "Meeting with Alex", location: "Home, Oslo, Tjuvholmen"),
createEvent(title: "Beach Volleyball", location: "Ipanema Beach, Rio De Janeiro"),
createEvent(title: "WWDC", location: "Moscone West Convention Center, 747 Howard St"),
createEvent(title: "Google I/O", location: "Shoreline Amphitheatre, One Amphitheatre Parkway"),
createEvent(title: "✈️️ to Svalbard ❄️️❄️️❄️️❤️️", location: "Oslo Gardermoen"),
createEvent(title: "💻📲 Developing CalendarKit", location: "🌍 Worldwide"),
createEvent(title: "Software Development Lecture", location: "Mikpoli MB310, Craig Federighi")
]
}
personal func createEvent(title: String, location: String) -> EventDescriptor {
let occasion = Occasion()
occasion.startDate = Date()
occasion.endDate = Date().addingTimeInterval(3600)
occasion.textual content = "(title)n(location)"
occasion.colour = .blue
occasion.isAllDay = false
occasion.userInfo = nil
return occasion
}
