和uicollectionView
我的设置是
PhotoListViewReactor.class
ReactorKit和class PhotoListViewReactor : Reactor {
enum Action {
case shareInit
case select(photo: Photo)
case deselect(photo: Photo)
case shareConfirm
case shareFinish
}
enum Mutation {
case selectShare(_ photo: Photo)
case deselectShare(_ photo: Photo)
case setSharingState(Bool)
case triggerShareAction
case shareComplete
}
struct State {
var sharePhotos: [Photo] = []
var isSharing: Bool = false
var shareAction: Bool = false
}
var initialState = State()
// init() { }
func mutate(action: Action) -> Observable<Mutation> {
switch action {
case .select(photo: let photo):
return Observable.just(Mutation.selectShare(photo)).takeUntil(self.action.filter(isSharingAction))
case .deselect(photo: let photo):
return Observable.just(Mutation.deselectShare(photo)).takeUntil(self.action.filter(isSharingAction))
case .shareInit:
return Observable.just(Mutation.setSharingState(true))
case .shareConfirm:
return Observable.concat([Observable.just(Mutation.triggerShareAction), Observable.just(Mutation.setSharingState(false))])
case .shareFinish:
return Observable.concat([Observable.just(Mutation.shareComplete),Observable.just(Mutation.setSharingState(false))])
}
}
func reduce(state: State, mutation: Mutation) -> State {
switch mutation {
case let .selectShare(photo):
var newState = state
newState.sharePhotos.append(photo)
return newState
case let .deselectShare(photo):
var newState = state
newState.sharePhotos.removeAll(where: { $0.id == photo.id })
return newState
case let .setSharingState(isSharing):
var newState = state
newState.isSharing = isSharing
return newState
case .triggerShareAction:
var newState = state
newState.shareAction = true
return newState
case .shareComplete:
var newState = state
newState.shareAction = false
newState.isSharing = false
newState.sharePhotos = []
return newState
}
}
private func isSharingAction(_ action: Action) -> Bool {
if case .shareInit = action {
return true
} else {
return false
}
}
}
内
PhotoListViewController要清除我的过滤器如果运算符：
self.collectionView.rx.modelSelected(Photo.self).share()
.filter(if: reactor.state.map{$0.isSharing})
.map {Reactor.Action.select(photo: $0)}
.bind(to: reactor.action)
.disposed(by: disposeBag)
self.collectionView.rx.modelDeselected(Photo.self).share()
.filter(if: reactor.state.map{$0.isSharing})
.map {Reactor.Action.deselect(photo: $0)}
.bind(to: reactor.action)
.disposed(by: disposeBag)
我的问题是选择和取消选择不能正常工作（选择后，用户无法再次单击以取消选择单元格）。我在uicollectionview中启用了多节。
答案 0 :(得分：0)
您必须使用find_difference的{{1}}和def assign_clusters_to_samples(data, clusters):
# clusters-array of clusters, sample-single sample from the database
def euclidean_distances(clusters, sample):
distances = np.sum((clusters - sample)**2, axis=1)
# return index with the minimal distance
return np.where(distances==np.min(distances))[0]
return [euclidean_distances(clusters, sample) for sample in data]
API。在使用UICollectionView选择索引路径之前，selectItem(at:animated:scrollPosition:)不会发出任何值。
