A most fully customization calendar library with swift

KVKCalendar

KVKCalendar is a most fully customization calendar library. Library consists of four modules for displaying various types of calendar (day, week, month, year). You can choose any module or use all. It is designed based on a standard iOS calendar, but with additional features. Timeline displays the schedule for the day and week.

Requirements

• iOS 10.0+
• Swift 5.0+

Installation

KVKCalendar is available through CocoaPods and Carthage.

CocoaPods

pod 'KVKCalendar'

Carthage

github "kvyatkovskys/KVKCalendar"

Usage

Import KVKCalendar.
Create a subclass view CalendarView and implement CalendarDataSource protocol. Create an array of class [Event] and return this array in the function.

import KVKCalendar

class ViewController: UIViewController {
    var events = [Event]()

    override func viewDidLoad() {
        super.viewDidLoad()
        
        let calendar = CalendarView(frame: frame)
        calendar.dataSource = self
        view.addSubview(calendar)
        
        createEvents { (events) in
            self.events = events
            self.calendarView.reloadData()
        }
    }
}

extension ViewController {
    func createEvents(completion: ([Event]) -> Void) {
        let models = // Get events from storage / API
        var events = [Event]()
        
        for model in models {
            var event = Event()
            event.id = model.id
            event.start = model.startDate // start date event
            event.end = model.endDate // end date event
            event.color = model.color
            event.isAllDay = model.allDay
            event.isContainsFile = !model.files.isEmpty
        
            // Add text event (title, info, location, time)
            if model.allDay {
                event.text = "\(model.title)"
            } else {
                event.text = "\(startTime) - \(endTime)\n\(model.title)"
            }
            events.append(event)
        }
        completion(events)
    }
}

extension ViewController: CalendarDataSource {
    func eventsForCalendar() -> [Event] {
        return events
    }
}

Implement CalendarDelegate to handle user action.

calendar.delegate = self

extension ViewController: CalendarDelegate {
    func didSelectDate(date: Date?, type: CalendarType) {
        print(date, type)
    }

    func didSelectEvent(_ event: Event, type: CalendarType, frame: CGRect?) {
        print(event)
    }
}

Styles

To customize calendar create an object Style and add to init class CalendarView.

var style = Style()
style.monthStyle.isHiddenSeporator = false
style.timelineStyle.offsetTimeY = 80
style.timelineStyle.offsetEvent = 3
style.allDayStyle.isPinned = true
style.timelineStyle.widthEventViewer = 500
let calendar = CalendarView(frame: frame, style: style)

If needed to customize Locale, TimeZone.

style.locale = Locale // create any
style.timezone = TimeZone //create any
