DurationPicker

DurationPicker is an iOS library that provides a customizable control for inputting time values ranging between 0 and 24 hours. It serves as a drop-in replacement of UIDatePicker with countDownTimer mode with additional functionality for time input.

Option to specify intervals for hour, minute, and/or seconds
Support for minimum and maximum durations
Localization in 26+ languages

Usage

To use DurationPicker, simply create an instance of DurationPicker and add it to your view hierarchy. You can customize your picker using the following properties:

pickerMode: The mode of the picker, determines whether the duration picker allows selection of hours, minutes, and/or seconds
{hour|minute|second}Interval: The intervals at which the duration picker should display
{minimum|maximum}Duration: The minimum/maximum duration that the picker can show

The code below will produce the following duration picker.

import DurationPicker

let picker = DurationPicker()
addSubview(picker)

picker.pickerMode = .minuteSecond
picker.minuteInterval = 5
picker.secondInterval = 30
picker.minimumDuration = (15 * 60) // 15 minutes
picker.maximumDuration = (45 * 60) + 30 // 45 minutes, 30 seconds

The selected duration can also be set programmatically through the duration property.

picker.duration = (30 * 60) + 30 // 30 minutes, 30 seconds

You can react to changes in the duration's picker value using UIActions.

let action = UIAction { [weak picker] _ in
    guard let picker else { return }
    print(picker.duration) // 1830
},
for: .primaryAction)
    
picker.addAction(action)
