ios - Swift 3 部分中的行数无效

Question

我有一个包含 Card() 类的数组字典，我有一个调用移动一个数组的函数的按钮

    static var DeliveryStatusArray =
    [
        "claimable": [Card](),
        "onTime": [Card](),
        "future": [Card](),
        "claimDone": [Card](),
        "tooOld": [Card](),
    ]

我移动卡的功能是

    static func moveCard(card:Card) -> Void {
    var pos:Int = -1
    var index:Int = 0
    while(index < (DashboardManager.DeliveryStatusArray["claimable"]?.count)!)
    {
        if (DashboardManager.DeliveryStatusArray["claimable"]?[index].idCard == card.idCard)
        {
            pos = index
        }
        index += 1
    }
    if (pos > -1)
    {
        let card:Card = (DashboardManager.DeliveryStatusArray["claimable"]?[pos])!
        DashboardManager.DeliveryStatusArray["claimable"]?.remove(at: pos)
        DashboardManager.DeliveryStatusArray["claimDone"]?.append(card)
    }
}

完成后，我会向我的 View 发布一条通知以调用此函数

    func notificationFinish(notification:Notification) -> Void{
        let sectionClaimable:Int = (api.dictionary["delivery"]?.index(of: "claimable"))! // Is 1
        let sectionClaiDone: Int = (api.dictionary["delivery"]?.index(of: "claimDone"))! // Is 4
        tableView.reloadSections(IndexSet(integer: sectionClaimable), with: .top)
        tableView.reloadSections(IndexSet(integer: sectionClaimDone), with: .top)
        return
    }

第一个循环我在 * DeliveryStatusArray["claimDone]* 中得到了 2 张卡，在调用 moveCard() 后我得到了三张卡

我收到错误

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 4. The number of rows contained in an existing section after the update (3) must be equal to the number of rows contained in that section before the update (2), plus or minus the number of rows inserted or deleted from that section (0 inserted, 0 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).'

重新加载数据时无法获取更多项目？

如果我理解正确的话，你的代码比它需要的要复杂得多......

// Get the index of card in claimable with matching idCard
guard let index = deliveryStatusArray["claimable"]?.index(where: {$0.idCard == card.idCard }) else { return }

// Remove the card at that index
let card = deliveryStatusArray["claimable"]?.remove(at: index)

// Append the card
deliveryStatusArray["claimDone"]?.append(card)
