    I have a tableView that uses a TKCalendar as the headerView and when the screen is rotated the Calendar switches from a Month View to Week View. The issue I'm having is that in the Week Mode I can scroll forward all I want, but can't scroll back to any date before the current date, but when I rotate the device back to switch into Month mode I can navigate forwards and backwards without any issues. Don't know what code to show so here's a few snippets. 

     Here's the setup of the calendar in viewDidLoad

    self.calendarView.autoresizingMask = [.FlexibleHeight, .FlexibleWidth]
    self.calendarView.dataSource = self
    self.calendarView.delegate = self
    self.calendarView.allowPinchZoom = false
    self.calendarView.selectionMode = TKCalendarSelectionMode.Single
    self.calendarView.viewMode = calendarViewMode
    //set the minimum and maximum date components
    let dateComponents = NSDateComponents()
    dateComponents.year = -5
    self.calendarMinDate = NSCalendar.currentCalendar().dateByAddingComponents(dateComponents, toDate: NSDate(), options: [])!
    dateComponents.year = 5
    self.calendarMaxDate = NSCalendar.currentCalendar().dateByAddingComponents(dateComponents, toDate: NSDate(), options: [])!
    self.calendarView.minDate = self.calendarMinDate
    self.calendarView.maxDate = self.calendarMaxDate


     This is what I have in the rotate interface function

    override func didRotateFromInterfaceOrientation(fromInterfaceOrientation: UIInterfaceOrientation) {
            //landscape mode should switch to week mode
            self.calendarView.viewMode = TKCalendarViewMode.Month
            if UIDevice.currentDevice().orientation.isLandscape {
                self.calendarView.viewMode = TKCalendarViewMode.Week
            //navigate to the current selected date as well
            self.calendarView.navigateToDate(self.selectedDate, animated: false)
            //make sure the table layout is updated


    This is the updatePresenter that is called when the device is rotated as well

    func updateCalendarPresenter() {
            var presenter = TKCalendarMonthPresenter()
            if self.calendarView.viewMode == TKCalendarViewMode.Week {
                presenter = self.calendarView.presenter as! TKCalendarWeekPresenter
                //the month presenter needs an additional item added
            else {
                presenter = self.calendarView.presenter as! TKCalendarMonthPresenter
                presenter.equalWeekNumber = false
            //hide the title view
            presenter.titleHidden = true
            //change the background color of the calendar
   = UIColor(hexString: ColorCodes.calendarBackground)
            //update case of cell
   = TKCalendarTextEffect.Uppercase
            //let the header stay as a sticky row
            presenter.headerIsSticky = true
            //update presenter
