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.

Features

• Styled to match UIDatePicker with countDownTimer mode
• Multiple modes for selection of hours, minutes, and/or seconds
• Option to specify intervals for hour, minute, and/or seconds
• Support for minimum and maximum durations
• Localization in 26+ languages
• Built-in support for accessibility and VoiceOver

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)
