Question

我有一个Tableview控制器，其中有9行。都是静态行，并且在具有票数的行中，所以我想动态更新它，只要数据中的数据更改也想在此处更改，我也想更新图像。那我怎么做......！

它更新，但每次我们必须构建它..然后值数将更新..！以下屏幕截图..！

    #import "LeftMenuViewController.h"
        #import "RKDropdownAlert.h"
        #import "HexColors.h"
        #import "AppConstanst.h"

总结你的问题是你需要一个逻辑来重新加载单个单元格。

这是您的解决方案。 您需要知道需要重新加载的单元格行的索引。

let indexPath = IndexPath(item: rowNumber, section: 0)
tableView.reloadRows(at: [indexPath], with: .top)

我想更新我的tableview静态单元格，如何更新它？
