Question

我在单元格中有一个自定义按钮，可以从可观察列表中删除项目。

self.searchListViewModel.genericList.value.remove(at: index)

所有逻辑都运行良好，但我需要一个动画来删除cell.Something like this

self.tableView.deleteRows(at: [IndexPath(row: index, section: 0)],
with: .fade)

但是现在，如果我尝试同时使用它们，应用程序会崩溃。

抱歉延误。以下是rxswift中可动画表视图的示例。

    enum MySectionItem {

        case a(presentable: APresentable)
        case b(presentable: BPresentable)
        case c(presentable: CPresentable)
    }

    extension MySectionItem: IdentifiableType, Equatable {
        typealias Identity = String

        var identity: Identity {
            switch self {
            case let .a(presentable):
                return presentable.title //Something which can define uniqueness
            case let .b(presentable):
                return presentable.title
            case let .c(presentable):
                return presentable.title
            }
        }
    }

对于SectionModel，您也可以这样做。

enum MySectionModel {

        case a(title: String, items: [MySectionItem])
        case b(title: String, items: [MySectionItem])
        case c(title: String, items: [MySectionItem])
    }

    extension MySectionModel: AnimatableSectionModelType {
        typealias Item = MySectionItem

        var items: [Item] {
            switch self {
            case let .a(title: _, items: items),
                 let .b(title: _, items: items),
                 let .c(title: _, items: items):

                return items.map { $0 }
            }
        }

        var identity: String {
            switch self {
            case let .a(title: title, items: _),
                 let .b(title: title, items: _),
                 let .c(title: title, items: _):

                return title
            }
        }

        init(original: MySectionModel, items: [Item]) {
            switch original {
            case let .a(title: title, items: _):
                self = .a(title: title, items: items)
            case let .b(title: title, items: _):
                self = .b(title: title, items: items)
            case let .c(title: title, items: _):
                self = .c(title: title, items: items)
            }
        }
    }
