【Swift】FSCalenderで日本時間を取得する方法

Swiftでカレンダーを簡単に作ることができるライブラリFSCalenderで日本時間を取得する方法です。

変換用のswiftファイルを作成する。

import Foundation
 

import UIKit
 

class DateUtils {
    class func dateFromString(string: String, format: String) -> Date {
        let formatter: DateFormatter = DateFormatter()
        formatter.calendar = Calendar(identifier: .gregorian)
        formatter.dateFormat = format
        return formatter.date(from: string)!
    }
 

    class func stringFromDate(date: Date, format: String) -> String {
        let formatter: DateFormatter = DateFormatter()
        formatter.calendar = Calendar(identifier: .gregorian)
        formatter.dateFormat = format
        return formatter.string(from: date)
    }
} 

ViewController.swiftを次のように記載します。

import UIKit
import FSCalendar;
 

class ViewController: UIViewController, FSCalendarDataSource, FSCalendarDelegate {
 

     @IBOutlet weak var calendar: FSCalendar!
     
     override func viewDidLoad() {
         super.viewDidLoad()
　　　　　 //ついでに日本語化
         self.calendar.appearance.headerDateFormat = "YYYY年MM月"
         self.calendar.calendarWeekdayView.weekdayLabels[0].text = "日"
         self.calendar.calendarWeekdayView.weekdayLabels[1].text = "月"
         self.calendar.calendarWeekdayView.weekdayLabels[2].text = "火"
         self.calendar.calendarWeekdayView.weekdayLabels[3].text = "水"
         self.calendar.calendarWeekdayView.weekdayLabels[4].text = "木"
         self.calendar.calendarWeekdayView.weekdayLabels[5].text = "金"
         self.calendar.calendarWeekdayView.weekdayLabels[6].text = "土"
         calendar.dataSource = self
         calendar.delegate = self
     }
     
     func calendar(_ calendar: FSCalendar, didSelect date: Date, at monthPosition: FSCalendarMonthPosition)
     {
         print(DateUtils.stringFromDate(date: date, format: "yyyy/MM/dd HH:mm:ss"))
     }
 }
