WatchKitTimePicker is a time picker data source for WatchKit that...
- Mirrors the behavior of UIKit's
UIDatePicker - Automatically uses either 12-hour or 24-hour time, depending on the user's current Locale.
- Supports watchOS 2.0+
WatchKitTimePicker is just one individual .swift file: TimePickerDataSource.swift. You could install it quickly by downloading that file and dragging it in to your Watch App Extension target.
Add github "calda/WatchKitTimePicker" to your Cartfile.
Unlike with iOS view-layer libraries, you can't just distribute and use a UIView or WKInterfaceObject subclass. Interface elements have to be set up using Interface Builder.
WatchKitTimePicker is a data source that controls and manages a group of WKInterfacePicker objects.
- Create a horizontal
WKInterfaceGroup. - Add three
WKInterfacePickerobjects to the group. - Connect and
@IBOutletand an@IBActionfor each of the pickers.
