I can set the initialDate but after view is loaded i am unable to change the selected date programmatically
datePicker.currentDate = Date().addingTimeInterval(3600*24))

Hi i set Custom Class of UIView to ADDatePicker and run the app.

hoping for a reply ASAP please

 datePicker.bgColor = .clear
 datePicker.deselectedBgColor = .clear
 datePicker.selectedBgColor = COLORS.Blue
    
 datePicker.selectedTextColor = .white
 datePicker.deselectTextColor = UIColor(hex: 0x1B9AFF).alpha(alpha: 0.7)

ADDatePicker(frame: .zero) method is not available as public

I love the design of this horizontal picker. Can we replace the text with images? I am interested in the carousel itself. Not the data picker. Thanks!

From debugging..it seems days model does't contain 31
so

let d = days.index { (modelObj) -> Bool in return Int(modelObj.type) == Int(dd) }

gives nil and crashes on days[d!].isSelected = true

The issue happens in devices in timezones other that GMT. The returned day is the previous day of the day picked by the user. That happens because when converting the date string to Date the timezone is not taken into account (DateFormatter assumes 00:00 for GMT). And if your timezone is not GMT when using or visualising the Date it is converted to YOUR timezone and if it is for example GMT-1, you date has been changed to the previous day at 23:00.

How to fix? The following change fixed the issue for me.
In CalendarHelper.swift change:

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MM/dd/yyyy"
if currentDay == "" {
       currentDay = (days.last?.type)!
}
let date = dateFormatter.date(from: "\(currentMonth)/\(currentDay)/\(currentYear)")

to

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MM/dd/yyyy"
if currentDay == "" {
       currentDay = (days.last?.type)!
}
dateFormatter.locale = Locale.current // Added line
dateFormatter.timeZone = TimeZone(secondsFromGMT: 0) // Added line
let date = dateFormatter.date(from: "\(currentMonth)/\(currentDay)/\(currentYear)")

I'd like to be able to limit the number of days we can scroll.

For example +/- 3 days from today (August 25th)

func limitScrollingOfDays(daysBefore before: Int, daysAfter after: Int, from selectedDate) {
    //TODO: Logic here
}

And be used like:

datePicker.limitScrollingOfDays(daysBefore: 3, daysAfter: 10, from: Date())

It should limit the number of scrolling days from August 22nd to September 4th

It seems the labels are miss-aligned. I've used Arial 16points font.
Maybe some calculation issues with a reminder? We did not check the code :)

Would be nice to find a fix for this bug 👍

Hi,

I want to update the date label text, while scrolling the date, month , row. Could you please update me regarding this?
Kindly let me know if you need more clarifications.

Thanks.

Error if iOS device preferred device language other than English.

Easy t test, just switch language from device Settings > General > Language & Region > Make any other language first on Preferred Language order.

Date picker will report error "Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value!" in CalendarHelper.swift "return date!" line 89

class func getYears(startYear: Int = 1980, endYear: Int = 2018) ;

I recommend changing the default value of endYear of the method func getYears(startYear:Int = 1980,endYear:Int = 2018) to the current year, otherwise it will crash if there is no age range set.

I Need a just month and year picker...i was thinking to give some -ve top dates section get hidden :D but not working...so can i have it as feature like a fixed height from user and then he can control what to show or option to make picker just for month and year

I'd like to be able to display weekdays inside the scrolls and decide if I want to display for example year or maybe number of days

Something like:

MON | TUE | WED | THUR | FRI | SAT | SUN
   1     |    2   |    3    |     4        5   |    6   |    7
JAN   | ....

And a method like:

func displayElements(_ elements: [ElementType]) {
    //Logic here
}

That would be called like:

datePicker.displayElements([.weekday, .day, .month])

The code above would display weekdays, days and months

While this one below would display only months and years:

datePicker.displayElements([.month, .year])

i have found an issue on leap year. after launching it current date. i am trying to move the year section (2016) and then month section (feb). after that i have found that 29th is selected but not moved to the selected area of the picker. this happen when our first launching current date is like 31-03-20
