json值是相同的，那么为什么在swift中的tableview在分页上进行计数

Question

如果total_count是0,1,2,3,4,5，则我需要增加每5个匹配的计数

1. ，然后pagenum = 1

2. 如果total_count是5,6,7,8,9,10然后Pagenum = 2 ...

对于例如，如果total_count为50，则pagenum = 50/5 = 10

这里

在 我已经编写了这样的代码currentPagenumbervm + = 1 + int（（self.paginationdata？result？.total_count ?? 0-1） / 5） / 5）< / code>。但是这里total_count保持不变。但是，当我刷新currentpagenumbervm一直在增加。如何解决这个问题？

var currentPageNumberVM: Int = 1
var isLoadingList: Bool = false

override func viewDidLoad() {
    super.viewDidLoad()
    self.currentPageNumberVM = 1
    self.PagenationMachesService(currentPageNumberVM)
}

private var paginationData = PaginationMaches(dictionary: NSDictionary())

func PagenationMachesService(_ pageNumber: Int) {

    let param = ["slug": slugVal ?? "", "page_no": currentPageNumberVM] as [String: Any]

    APIReqeustManager.sharedInstance.serviceCall(
        param: param as [String: Any], method: .post, url: CommonUrl.get_matches
    ) { [weak self] (resp) in

        if (self?.currentPageNumberVM)! > 1 {
            if (PaginationMaches(dictionary: resp.dict as NSDictionary? ?? NSDictionary())?.result?
                .matches ?? [Matches]()).count != 0
            {
                self?.paginationData?.result?.matches! +=
                    PaginationMaches(dictionary: resp.dict as NSDictionary? ?? NSDictionary())?
                    .result?.matches ?? [Matches]()
            } else {
                self?.showSingleButtonAlertWithoutAction(title: "NO more data to show")
            }
        } else {
            self?.paginationData = PaginationMaches(
                dictionary: resp.dict as NSDictionary? ?? NSDictionary())
        }

        self?.isLoadingList = false
        self?.machesTable.reloadData()
    }
}

@objc func refresh() {
    self.currentPageNumberVM += 1 + Int((self.paginationData?.result?.total_count ?? 0 - 1) / 5)
    self.PagenationMachesService(currentPageNumberVM)
}

extension MatchesVC {
    func scrollViewDidEndDragging(_ scrollView: UIScrollView, willDecelerate decelerate: Bool) {

        if (scrollView.contentOffset.y + scrollView.frame.size.height)
            >= scrollView.contentSize.height
        {
            self.isLoadingList = true
            self.refresh()
        }
    }
}

您正在增加CurrentPageNumberVM的值，因为您正在使用“添加分配运算符” +=。

将其更改为“分配”操作员=，它应该正常工作。

self.currentPageNumberVM = 1 + Int((self.paginationData?.result?.total_count ?? 0 - 1) / 5)
