问题描述
我试图将三种类型的单元格放在一个tableView中，
使用rxSwift，第一个部分有两个项目，第二个有43个项目，最后一个有16个项目，
但是tableView每节仅显示一项
您可以在下图中看到错误
好的，这是代码
class OrdersVC: BaseViewController {
@IBOutlet weak var ordersTabel: UITableView!
public let orders : PublishSubject<OrdersTypeModel> = PublishSubject()
var ordersDecoded = OrdersTypeModel()
var delivery = Array<DetailsModel>()
var takeAway = Array<DetailsModel>()
var history = Array<OrderModel>()
let disposeBag = disposeBag()
override func viewDidLoad() {
super.viewDidLoad()
ordersTabel.allowsSelection = false
setupBindings()
}
private func setupBindings() {
ordersTabel.register(UINib(nibName: "DeliveryCell",bundle: nil),forCellReuseIdentifier: String(describing: DeliveryCell.self))
ordersTabel.register(UINib(nibName: "TakeAwayCell",forCellReuseIdentifier: String(describing: TakeAwayCell.self))
ordersTabel.register(UINib(nibName: "HistoryCell",forCellReuseIdentifier: String(describing: HistoryCell.self))
ordersTabel.rx.willdisplayCell
.subscribe(onNext: ({ (cell,indexPath) in
let transform = CATransform3DTranslate(CATransform3DIdentity,-250,0)
cell.layer.transform = transform
UIView.animate(withDuration: 1,delay: 0,usingSpringWithdamping: 0.7,initialSpringVeLocity: 0.5,options: .curveEaSEOut,animations: {
cell.alpha = 1
cell.layer.transform = CATransform3DIdentity
},completion: nil)
})).disposed(by: disposeBag)
orders
.observeOn(MainScheduler.instance)
.subscribe(
onNext: { [self] in
print("ononon onNext: \($0)")
ordersDecoded = $0
delivery = ordersDecoded.orderdelivery
delivery2.onNext(delivery)
takeAway = ordersDecoded.ordertakeaway
takeAway2.onNext(takeAway)
history = ordersDecoded.orders1
history2.onNext(history)
print("ononon onNext: \(delivery.count),\(takeAway.count),\(history.count)")
let sections: [MultipleSectionModel] = [
.DeliverySection(title: "Delivery",items: [.DeliveryItem(model: delivery)]),.TakeAwaySection(title: "Take Away",items: [.TakeAwayItem(model: takeAway)]),.HistorySection(title: "History",items: [.HistoryItem(model: history)])
]
let dataSource = OrdersVC.dataSource()
Observable.just(sections)
.bind(to: ordersTabel.rx.items(dataSource: dataSource))
.disposed(by: disposeBag)
},onError: { print("ononon onError: \($0)") },onCompleted: { print("ononon onCompleted") },ondisposed: { print("ononon ondisposed") }
)
.disposed(by: disposeBag)
}
}
extension OrdersVC {
static func dataSource() -> RxTableViewSectionedReloadDataSource<MultipleSectionModel> {
return RxTableViewSectionedReloadDataSource<MultipleSectionModel>(
configureCell: { dataSource,table,idxPath,_ in
print("sjdkhbgdjkf \(idxPath)")

return cell
case let .TakeAwayItem(model):

for i in 0 ... model.count - 1 {
let cell: TakeAwayCell = table.dequeueReusableCell(withIdentifier: "TakeAwayCell",for: idxPath) as! TakeAwayCell
cell.model = model[i]
print("sjdkhbgdjkf2 \(i)")
return cell
}
case let .HistoryItem(model):
print("sjdkhbgdjkf3 \(model.count)")
for i in 0 ... model.count - 1 {
let cell: HistoryCell = table.dequeueReusableCell(withIdentifier: "HistoryCell",for: idxPath) as! HistoryCell
cell.model = model[i]
print("sjdkhbgdjkf3 \(i)")
return cell
}
}
return table.dequeueReusableCell(withIdentifier: "HistoryCell",for: idxPath) as! HistoryCell
},titleForHeaderInSection: { dataSource,index in
let section = dataSource[index]
if section.title == "History" {
return section.title
} else {
return nil
}
}
)
}
}
enum MultipleSectionModel {
case DeliverySection(title: String,items: [SectionItem])
case TakeAwaySection(title: String,items: [SectionItem])
case HistorySection(title: String,items: [SectionItem])
}
extension MultipleSectionModel: SectionModelType {
typealias Item = SectionItem
var items: [SectionItem] {
switch self {
case .DeliverySection(title: _,items: let items):
return items.map { $0 }
case .TakeAwaySection(title: _,items: let items):
return items.map { $0 }
case .HistorySection(title: _,items: let items):
return items.map { $0 }
}
}
init(original: MultipleSectionModel,items: [Item]) {
switch original {
case let .DeliverySection(title: title,items: _):
self = .DeliverySection(title: title,items: items)
case let .TakeAwaySection(title: title,items: _):
self = .TakeAwaySection(title: title,items: items)
case let .HistorySection(title,_):
self = .HistorySection(title: title,items: items)
}
}
}
extension MultipleSectionModel {
var title: String {
switch self {
case .DeliverySection(title: let title,items: _):
return title
case .TakeAwaySection(title: let title,items: _):
return title
case .HistorySection(title: let title,items: _):
return title
}
}
}
enum SectionItem {
case DeliveryItem(model: Array<DetailsModel>)
case TakeAwayItem(model: Array<DetailsModel>)
case HistoryItem(model: Array<OrderModel>)
}
tableView仅显示3个项目。
for i in 0 ... model.count - 1 {
let cell: HistoryCell = table.dequeueReusableCell(withIdentifier: "HistoryCell",for: idxPath) as! HistoryCell
cell.model = model[i]
print("sjdkhbgdjkf3 \(i)")
return cell
}
我注意到，尽管计数超过1，但它没有循环
感谢您的帮助
解决方法
您使截面模型变得比所需的复杂得多，我猜测结果是，您开始跳过箍以尝试其余部分进行编译。这是您的代码经过重新编写，它应该可以使您跳出更好的起点。
