Jtapplecalendar: Error while changing endDate dynamically – cellCacheSection does not exist

[PedroAnibarro1]

Hi!

First congratulation and thanks for the awesome job with this library.

Using version 7.1.4

OK,

So, I have a datePicker to select the startDate and the endDate. When the user changes either one, I'm calling reloadData() on the calendar. When I modify the startDate the calendar works as expected.

Now, when I change the endDate and call reloadData()

developerError is called in this part of the code of the collectionView numberOfItemsInSection

     public func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        if calendarViewLayout.cellCache.isEmpty {return 0}
        guard let count =  calendarViewLayout.cellCache[section]?.count else {
            developerError(string: "cellCacheSection does not exist.")
            return 0
        }
        return count
    }

Any idea of what's happening? Is there a correct way of updating dynamically the calendar view?

hmm. this should not be happening.
Let me try to replicate this on my sample app.
Will respond here in a bit.

Hey I just tested this on the sample application I have, and i cannot reproduce you issue.
Do you have a zipped empty sample app that can demonstrate the issue? You can drop it in this chat box or send to [email protected]

Okay so I found my problem.

I had in layoutSubviews() this code

self.calendarView.ibCalendarDelegate = self
 self.calendarView.ibCalendarDataSource = self      

So I figured out that that may be the problem and I changed it to

       // Set Calendar Delegates
        if self.calendarView.ibCalendarDelegate == nil && self.calendarView.ibCalendarDataSource == nil {
            self.calendarView.ibCalendarDelegate = self
            self.calendarView.ibCalendarDataSource = self
        }

And problem solved!

To give a little of context, I have this code in layoutSubviews() because I was having problems with awakeFromNib being called before one of my variables be initialized (the calendar is inside a table view cell).

Sorry for taking your time. Hope this helps someone.

Its cool.
good its fixed.
