iOS swift: selecting a cell I want to select the entire row - ios

Question

I have a calendar, and I want to select an entire row (week) when I select a day.. this is my code so far:
//When a date is selected
func calendar(_ calendar: JTAppleCalendarView, didSelectDate date: Date, cell: JTAppleCell?, cellState: CellState) {
selectTheWeek(of: date)
setupLayoutCell(cell: cell, cellState: cellState)
}
func selectTheWeek(of date: Date) {
let starOfTheWeek = date.startOfWeek()
let endOfTheWeeK = date.endOfWeek()
calendarCollectionView.selectDates(from: starOfTheWeek, to: endOfTheWeeK)
}
extension Date {
func startOfWeek() -> Date {
let calendar = Calendar.autoupdatingCurrent
let currentDateComponents = calendar.dateComponents([.yearForWeekOfYear, .weekOfYear], from: self)
return calendar.date(from: currentDateComponents)!
}
func endOfWeek() -> Date {
let cal = Calendar.autoupdatingCurrent
var component = DateComponents()
component.weekOfYear = 1
component.day = -1
return cal.date(byAdding: component, to: startOfWeek())!
}
}
the problem is that I'm having an infinite loop, and it's clear the reason.
But I don't know how to prevent it. Any help?
JTAppleCalender is an external library. It's an extension of a collectionView.

Answer 1

You can use 2 techniques to break the loop.
First:
calendarViewselectDates(from: starOfTheWeek, to: endOfTheWeeK, triggerSelectionDelegate: false)
By setting triggerSelectionDelegate to false, your delegate function didSelect will not be called.
Second:
If you are using MasterBranch code (which i'll be releasing in a week or so), you can know whether or not your selection is programmer initiated vs user initiated. You know this by --> cellState.
if cellState.selectionType == .programatic {
// ignore stuff
} else {
// Do stuff
}
You can put this if statement in your shouldSelect function.

Answer 2

I know this is a not the best possible solution but it could work to avoid your issue
//When a date is selected
var shouldSelectWeek = true
func calendar(_ calendar: JTAppleCalendarView, didSelectDate date: Date, cell: JTAppleCell?, cellState: CellState) {
if shouldSelectWeek{
selectTheWeek(of: date)
shouldSelectWeek = false
}
setupLayoutCell(cell: cell, cellState: cellState)
}
func selectTheWeek(of date: Date) {
let starOfTheWeek = date.startOfWeek()
let endOfTheWeeK = date.endOfWeek()
calendarCollectionView.selectDates(from: starOfTheWeek, to: endOfTheWeeK)
}
extension Date {
func startOfWeek() -> Date {
let calendar = Calendar.autoupdatingCurrent
let currentDateComponents = calendar.dateComponents([.yearForWeekOfYear, .weekOfYear], from: self)
return calendar.date(from: currentDateComponents)!
}
func endOfWeek() -> Date {
let cal = Calendar.autoupdatingCurrent
var component = DateComponents()
component.weekOfYear = 1
component.day = -1
return cal.date(byAdding: component, to: startOfWeek())!
}

Answer 3

Just add a new boolean variable like var shouldIgnoreDateSelection = false and then you just do
func calendar(_ calendar: JTAppleCalendarView, didSelectDate date: Date, cell: JTAppleCell?, cellState: CellState) {
if shouldIgnoreDateSelection == false {
selectTheWeek(of: date)
}
setupLayoutCell(cell: cell, cellState: cellState)
}
func selectTheWeek(of date: Date) {
let starOfTheWeek = date.startOfWeek()
let endOfTheWeeK = date.endOfWeek()
shouldIgnoreDateSelection = true
calendarCollectionView.selectDates(from: starOfTheWeek, to: endOfTheWeeK)
shouldIgnoreDateSelection = false
}
