Uidatepicker Select Month and Year

UIDatePicker select Month and Year

Yeah, you probably want to just make your own picker. You don't have to subclass it or anything, though; just use a generic UIPickerView and return appropriate values from your UIPickerViewDelegate/UIPickerViewDataSource methods.

Setting the Datepicker in IOS to pick only the Month and Year

Your question mentions date and year so I it seemed like UIDatePickerModeDate would suffice but as you are looking for month and year which is not an available option. I suggest you consider using a two component UIPickerView object.

Original Answer

You can do this by changing the Mode property under Date Picker to Date in the Attributes Inspector in the right bar ( Cmd + Option + 4 ). You can also do this programmatically,

datePicker.datePickerMode = UIDatePickerModeDate;

UIDatePicker, display Full Date with YEAR and time

Yes you can. But you will need to combine both. Use the picker view for the years and set your date picker minimum to the first day of the selected year and the maximum to the last day of that year. You will need also to set your UIDatePicker property [datePickerMode][1] to .dateAndTime

import UIKit

class ViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {
    @IBOutlet weak var pickerView: UIPickerView!
    @IBOutlet weak var datePicker: UIDatePicker!
    let years = Array(Date().year-3...Date().year+3)
    var date = Date()
    var lastIndex = 3
    override func viewDidLoad() {
        super.viewDidLoad()
        pickerView.delegate = self
        pickerView.dataSource = self
        datePicker.date = Date()
    }
    @IBAction func dateChanged(_ datePicker: UIDatePicker) {
        date = datePicker.date
        print(datePicker.date.year)
        print(datePicker.date)
    }
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        pickerView.selectRow(3, inComponent: 0, animated: true)
        setDatePickerMinimumAndMaximumDatesFor(year: years[3])
    }
    func pickerView(_ pickerView: UIPickerView,
                    numberOfRowsInComponent component: Int) -> Int {
        return years.count
    }
    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        return String(years[row])
    }
    func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 1
    }
    func setDatePickerMinimumAndMaximumDatesFor(year: Int) {
        datePicker.minimumDate = year.firstDayOfTheYear
        datePicker.maximumDate = year.lastDayOfTheYear
    }

    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
setDatePickerMinimumAndMaximumDatesFor(year: years[row])
        if let optionalDate = Calendar.current.date(byAdding: .year, value: (lastIndex > row ? row - lastIndex :  -(lastIndex - row)), to: date) {
            datePicker.date = optionalDate
        }
        print(datePicker.date.year)
        print(datePicker.date)
    }
}
extension Date {
    var year: Int {
        return Calendar.current.component(.year, from: self)
    }
}
extension Int {
    var firstDayOfTheYear: Date {
        return DateComponents(calendar: .current, year: self, month: 1, day: 1).date!
    }
    var lastDayOfTheYear: Date {
        return DateComponents(calendar: .current, year: self, month: 12, day: 31).date!
    }
}

Swift Month year pickerView with last 12 months

This is a simple example to get the last 12 months

var last12Months = [Date]()
let firstDayComponent = DateComponents(day: 1)
Calendar.current.enumerateDates(startingAfter: Date(), 
                 matching: firstDayComponent, 
                 matchingPolicy: .nextTime, 
                 direction: .backward, 
                 using: { (date, idx, stop) in
    if let date = date {last12Months.append(date) }
    if last12Months.count == 12 { stop = true }
})

print(last12Months)
let formatter = DateFormatter()
formatter.dateFormat = "MMMM yyyy"
print(last12Months.map({formatter.string(from: $0)}))
