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..！

答案 0 :(得分：1)
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)
