[1차] tableView.rx.items
를 활용해서 바인딩
viewModel.subject
.bind(to: tableView.rx.items(
cellIdentifier: "Cell",
cellType: UITableViewCell.self)) { index, item, cell in
cell.textLabel?.text = item.detailHash
}.disposed(by: disposeBag)
[2차] tableView.rx.items
는 section이 하나 이상일 때는 사용하기 어렵다. RxDataSources 활용하는 방법으로 변경
private let dataSource = RxTableViewSectionedReloadDataSource<SectionOfData>(
configureCell: { (_, tableView, indexPath, element) in
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell")!
cell.textLabel?.text = element.title
return cell
},
titleForHeaderInSection: { dataSource, sectionIndex in
return dataSource[sectionIndex].header
}
)
[3차] main, soup, side의 순서(section)를 보장하기 위해 Category
속성을 section model에 추가하고,
정렬된 sections 데이터를 방출하도록 개선 -> 순서를 보장하기 위해 매번 전체 table이 reload 되어야 하는 구조
enum Category: Int {
case main = 1
case soup
case side
}
private var sections: [SectionOfData] = [] {
didSet {
sections.sort { $0.category < $1.category }
}
}
[4차] 전체 section 대신, 먼저 받아온 데이터(main, soup, side)만 reload 할 수 없을까?
IndexSet 이벤트를 방출하고, 해당 index의 section을 reload 하도록 변경
이 때, 메인 큐에 sync로 수행하지 않으면 crash가 발생한다.
// in view model
var subject = PublishSubject<IndexSet>()
// in controller
viewModel.subject
.subscribe(onNext: { data in
DispatchQueue.main.sync {
self.tableView.reloadSections(data, with: .automatic)
}
})
.disposed(by: disposeBag)
회고
- RxDataSources를 사용했더라도, SectionOfData를 미리 생성해두고 각 section에 해당하는 data가 왔을 때 이벤트를 방출하면 의도한대로 구현 가능하지 않았을까
