17. ViewController Interactor DataStore Router Data Passing Routing
18. Workshop Practice
20. 基礎版 進階版
23. Interactor Presenter ViewController Request Response ViewModel struct Request { } struct ViewModel { let historyEvents: [] let recentlyEvents: [] } struct Response { let recentlyEvents: [EventResponseItem] let historyEvents: [EventResponseItem] }
24. enum MeetupEventList { enum FetchEvents { struct Request { } struct Response { let recentlyEvents: [EventResponseItem] let historyEvents: [EventResponseItem] } struct ViewModel { let historyEvents: [DisplayHistoryEvent] let recentlyEvents: [DisplayRecentlyEvent] } } }
25. Presentation Model
26. struct DisplayRecentlyEvent { let id: String let title: String let dateText: String let hostName: String let coverImageURL: URL? }
27. struct DisplayHistoryEvent { let id: String let title: String let dateText: String let hostName: String let coverImageURL: URL? let favoriteButtonColor: UIColor }
28. How?
29. class MeetupEventListViewController: UIViewController { } var recentlyEvents: [MeetupEvent] = [] var historyEvents: [MeetupEvent] = [] ViewController (MVC)
30. var recentlyEvents: [MeetupEventList.DisplayRecentlyEvent] = [] var historyEvents: [MeetupEventList.DisplayHistoryEvent] = [] protocol MeetupEventListDisplayLogic: AnyObject { func displayMeetupEvents( viewModel: MeetupEventList.FetchEvents.ViewModel ) } class MeetupEventListViewController: UIViewController, MeetupEventListDisplayLogic { } ViewController (Clean Swift)
31. meetupEventListAPI.fetchMeetupEvents { [weak self] result in guard let self = self else { return } switch result { case let .success((recentlyEvents, historyEvents)): self.recentlyEvents = self.recentlyEvents self.historyEvents = self.historyEvents self.tableView.reloadData() case let .failure(error): print("#### error -> \(error)") } } loadData( ) (MVC)
32. let request: MeetupEventList.FetchEvents.Request = .init() interactor?.fetchMeetupEvents(request: request) loadData( ) (Clean Swift)
33. func configureCell(with meetupEvent: MeetupEvent) { titleLabel.text = meetupEvent.title hostNameLabel.text = meetupEvent.hostName if let eventDate = meetupEvent.date { dateLabel.text = getDateText(with: eventDate) } else { dateLabel.text = "" } coverImageView.image = nil if let coverImageUrl = meetupEvent.coverImageLink, let url = URL(string: coverImageUrl) { coverImageView.isHidden = false coverImageView.kf.setImage(with: url) } else { coverImageView.isHidden = true } } Configure Cell (MVC)
34. func configureCell( with meetupEvent: MeetupEventList.DisplayRecentlyEvent ) { titleLabel.text = meetupEvent.title hostNameLabel.text = meetupEvent.hostName dateLabel.text = meetupEvent.dateText coverImageView.image = nil if let url = meetupEvent.coverImageURL { coverImageView.isHidden = false coverImageView.kf.setImage(with: url) } else { coverImageView.isHidden = true } } Configure Cell (Clean Swift)
35. protocol MeetupEventListBusinessLogic { func fetchMeetupEvents( request: MeetupEventList.FetchEvents.Request ) } class MeetupEventListInteractor: MeetupEventListBusinessLogic{ var fetchMeetupEventWorker: MeetupEventListAPIWorker func fetchMeetupEvents( request:MeetupEventList.FetchEvents.Request ) { } } Interactor (Clean Swift)
36. protocol MeetupEventListPresentationLogic { func presentMeetupEvents( response: MeetupEventList.FetchEvents.Response ) } class MeetupEventListPresenter:MeetupEventListPresentationLogic { func presentMeetupEvents( response: MeetupEventList.FetchEvents.Response ){ } } Presenter (Clean Swift)
