A micro-post about a micro-framework. Schedule (possibly repeating) events for some time in the future, along with restoration support. An NSNotification-based scheduling service in Swift.
- Schedule a request
- Cancel a request
- Restore all requests upon app-launch
- Pause/resume all requests
Essentially I wanted to remove the knowledge/management of a timer. Obviously the implementation would need to handle this, but I wanted to build an abstraction on top of this that would support all of my requirements, while providing a simple/clean API.
The result is a lightweight micro-framework – SchedulingService.
// schedule a request let request = service.schedule(date: Date().addingTimeInterval(5)) // cancel the request service.cancel(request) // schedule an NSNotification service.schedule(date: Date().addingTimeInterval(20), notification: .CountdownDidUpdate)
I also wanted to be able to save/restore all scheduled events so that I wouldn’t need to restore them manually upon launch.
// decodes or makes a new Service let store = SchedulingServiceStore(service: nil) // encodes the current service store.service.save()
Super simple, single file micro-framwork.
