[sambong0113]

IMPORTANT - BEFORE CREATING YOUR ISSUE PLEASE READ THE FOLLOWING:

1. PLEASE STATE THE VERSION NUMBER you are using.
2. Are you using the latest version of JTAppleCalendar? Latest version is currently 7.1.5
3. PROVIDE ENOUGH INPORMATION SO I CAN RECREATE THE PROBLEM.

I use an xcode 9.4.1, swift 4, jtapplecalendar 7.1.0
I just do a https://www.youtube.com/watch?v=zOphH-h-qCs tutorials and #553
this is my code.

`

import UIKit
import JTAppleCalendar

class ViewController: UIViewController {
let formatter = DateFormatter()

override func viewDidLoad(){
    super.viewDidLoad()
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

}

extension ViewController: JTAppleCalendarViewDataSource, JTAppleCalendarViewDelegate {

func calendar(_ calendar: JTAppleCalendarView, willDisplay cell: JTAppleCell, forItemAt date: Date, cellState: CellState, indexPath: IndexPath) {
    let mycell = cell as! CustomCell
    mycell.dateLabel.text = cellState.text
}



func calendar(_ calendar: JTAppleCalendarView, cellForItemAt date: Date, cellState: CellState, indexPath: IndexPath) -> JTAppleCell {
    let mycell = calendar.dequeueReusableJTAppleCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCell
    mycell.dateLabel.text = cellState.text
    self.calendar(calendar, willDisplay: mycell, forItemAt: date, cellState: cellState, indexPath: indexPath)
    return mycell
}

func configureCalendar(_ calendar: JTAppleCalendarView) -> ConfigurationParameters {
    formatter.dateFormat="yyyy MM dd"
    formatter.timeZone=Calendar.current.timeZone
    formatter.locale = Calendar.current.locale
    
    let startDate = formatter.date(from: "2017 01 01")!
    let endDate = formatter.date(from: "2019 12 31")!
    
    let parameters = ConfigurationParameters(startDate: startDate, endDate: endDate)
    return parameters
}

}
`

what do i wrong??

[sambong0113]

I'm sorry. I do not set identifier in the custom cell..

[myazdani2010]

I have the same issue. following the same video tutorial and implemented both willDisplay and cellForItemAt but they never get called.

I am using: Xcode: 10.1, JTAppleCalendar: 7.1.6, Swift: 4.2, Deployment target: iOS 12.1

Code:

import UIKit
import JTAppleCalendar

class ViewController: UIViewController {

    let formatter = DateFormatter()
    
    
    @IBOutlet weak var calendarView: JTAppleCalendarView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        print("ViewController : viewDidLoad")
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        print("ViewController : didReceiveMemoryWarning")
    }


}



extension ViewController : JTAppleCalendarViewDelegate, JTAppleCalendarViewDataSource {
    
    func calendar(_ calendar: JTAppleCalendarView, willDisplay cell: JTAppleCell, forItemAt date: Date, cellState: CellState, indexPath: IndexPath) {
        print("ViewController : willDisplay")
        let myCustomCell = cell as! CustomCell
        sharedFunctionToConfigureCell(myCustomCell: myCustomCell, cellState: cellState, date: date)
    }
    
    
    
    func calendar(_ calendar: JTAppleCalendarView, cellForItemAt date: Date, cellState: CellState, indexPath: IndexPath) -> JTAppleCell {
        print("ViewController : cellForItemAt")
        
        let cell = calendar.dequeueReusableJTAppleCell(withReuseIdentifier: "CustomeCell", for: indexPath) as! CustomCell
        sharedFunctionToConfigureCell(myCustomCell: cell, cellState: cellState, date: date)
        return cell
    }
    
    
    
    func sharedFunctionToConfigureCell(myCustomCell: CustomCell, cellState: CellState, date: Date) {
        print("ViewController: sharedFunctionToConfigureCell")
        myCustomCell.dateLabel.text = cellState.text
    }

    
   
    func configureCalendar(_ calendar: JTAppleCalendarView) -> ConfigurationParameters {
        print("ViewController : configureCalendar")
        
        formatter.dateFormat = "yyyy MM dd"
        formatter.timeZone = Calendar.current.timeZone
        formatter.locale = Calendar.current.locale
        
        let startDate = formatter.date(from: "2017 01 01")!
        let endDate = formatter.date(from: "2017 12 31")!
        
        let parameters = ConfigurationParameters(startDate: startDate, endDate: endDate)
        return parameters
    }
    
    
}

I followed the view tutorial multiple times to make sure I am not missing anything. Not sure what is wrong!

[patchthecode]

zip your sample prject, and send the zip file to me by dragging it into this chat box.
i'll take a look

[myazdani2010]

here is the project: CalendarTest.zip

[myazdani2010]

@patchthecode any updates? Sorry I am curious to know what is the issue.

[patchthecode]

sorry man. my bad.
i totally missed this because this is a closed issue.
usually i dont miss it if the issue is open.

let me check.
In future, lets create a new issue for things like this.

[myazdani2010]

Sure @patchthecode, will create new issue next time.

[patchthecode]

@myazdani2010 i just looked at you Podfile, and inside it you have
7.0
you do not have 7.1.6
Probably this is the issue?

[myazdani2010]

Sorry, that didn't work. Thank you for your time @patchthecode

[patchthecode]

I am not sure what the problem is then.
Here, i added 7.1.6 to the podfile.
I then did a pod update
i put the project on 12.0 deployment target and every thing is working fine.
here is the file.

CalendarTest 3.zip

[myazdani2010]

Don't know why it's still the same for me. I had simulator running on iOS 12.1 and I downgrade it to iOS 12.0. Unfortunately still facing the same issue!

[patchthecode]

did the zip file i sent you work for you?

[myazdani2010]

No, it didn't work. Thank you though
