Date Pickers
A date picker lets the user choose a date, a time, a date and time, or a range of dates. Both Gregorian and non-Gregorian calendars are supported.
Choose a style that suits your app. There are two styles of date pickers: textual and graphical. The textual style is useful when space is constrained and you expect users to make specific date and time selections. The graphical style is useful when you want to give users the option of browsing through days in a calendar, when you want to let the user select a range of dates, or when the look of a clock face is appropriate for the user interface of your app.
For developer guidance, see NSDatePicker.
Textual Style
This style is represented by a text field containing one of the following combinations of date and time elements.
Combination | Date | Time |
---|---|---|
Date and time | Month, day, and year | Hour, minute, and second |
Date and time | Month, day, and year | Hour and minute |
Date and time | Month and year | Hour, minute, and second |
Date and time | Month and year | Hour and minute |
Date only | Month, day, and year | None |
Date only | Month and year | None |
Time only | None | Hour, minute, and second |
Time only | None | Hour and minute |
After selecting an element in the date or time field, users can enter a new value, or press the Up or Down Arrow keys to increment or decrement the element’s value, respectively. Date and time fields include a stepper by default, which the user can also use to increment and decrement the selected element’s value. You may choose to hide the stepper, if that makes sense for your app.
The order of elements displayed in a textual date picker may vary based on the user’s locale. For example, people in most European locales will see the date elements in DD-MM-YYYY order, while others in the world may use YYYY-MM-DD or MM-DD-YYYY, depending on their location. Users can change their locale in System Preferences > Language & Region > Region.
Graphical Style
When using a graphical calendar, people can navigate to and select a specific date, or—if enabled by your app—a range of dates. With a graphical clock, the user can change the time by dragging the hands to a new position.

makes it possible to pick a value from a list by scrolling individualcomponents of a wheel-like interface.Pickers are frequently used to select a date and time; Apple provides the
UIDatePicker
class for this purpose.The article describes how to implement and use the

Working with a picker control
A picker uses a model to interact with data:
The
UIPickerViewModel
base class implements two interfaces,IUIPickerDataSource
and IUIPickerViewDelegate
,which declare various methods that specify a picker's data and how ithandles interaction:A picker can have multiple columns, or components. Components partitiona picker into multiple sections, allowing for easier and more specific dataselection:

To specify the number of components in a picker, use the

method.Customizing a picker's appearance
To customize the appearance of a picker, use the
UIPickerView.UIPickerViewAppearance
class or override the GetView
and GetRowHeight
methods in the UIPickerViewModel

Date picker properties
Minimum and maximum date
MinimumDate
and MaximumDate
limit the range of dates available in the date picker. For example, thefollowing code constrains a date picker to the sixty years leading up tothe present moment:Tip
It's possible to explicitly cast a
DateTime
to an NSDate
:Minute interval
The
MinuteInterval
property sets the interval at which the picker will display minutes:Mode
Date pickers support fourmodes,described below:
UIDatePickerMode.Time
UIDatePickerMode.Time
displays the time with an hour and minute selectorand an optional AM or PM designation:Microsoft Date And Time Picker Control Mac 10
UIDatePickerMode.Date
UIDatePickerMode.Date
displays the date with a month, day, and yearselector:The order of the selectors depends on the date picker's locale, which bydefault uses the system locale. The image above shows the layout of theselectors in the
en_US
locale, but the following changes the order toDay | Month | Year:UIDatePickerMode.DateAndTime
UIDatePickerMode.DateAndTime
displays a shortened view of the date, thetime in hours and minutes, and an optional AM or PM designation (dependingon whether a 12 or 24 hour clock is used):As with
UIDatePickerMode.Date
, the order ofthe selectors and the use of a 12 or 24 hour clock depends on the locale ofthe date picker.Tip
Use the
Date
property to capture the value of a date picker in modeUIDatePickerMode.Time

, orUIDatePickerMode.DateAndTime
. This value is stored as an NSDate
.UIDatePickerMode.CountDownTimer
UIDatePickerMode.CountDownTimer
displays hour and minute values:The
CountDownDuration
property captures the value of a date picker inUIDatePickerMode.CountDownTimer
mode. For example, to add the countdownvalue to the current date:NSDateFormatter
To format an
NSDate
, use anNSDateFormatter
.To use an

, call its ToString
method. For example:DateFormat
