Ios 返回DetailTableView（swift）中的数据

在我的应用程序中，我有两个表视图。第一个表视图有一组单元格。这些单元格将始终是相同的，并且永远不会更改。上面的表视图将始终具有4个单元格，而不会更多。在我的服务器上，我有我的API，其中每个单元都有路由

例如：

获取-myAPI/Air

获取-myAPI/历史记录

获取-myAPI/列车

获取-myAPI/出租车

每个路由发送回不同的数据

mainTablewView：

和邮政

当用户选择单元格时，您为需要调用的API设置了正确的值。一旦您这样做，didSet中的代码将被执行，它应该调用调用相应API的函数

要查看其他tableView，请执行以下操作：

---

mainTableView和Air cell是正常的，但是当所选的另一个返回相同的信息Air cell时？

也许我只是错过了它，但是我可以看到您创建的NSURLSession看起来很好，但是我看不到您在创建它之后在哪里调用它。如果您不调用

.resume（）

，它甚至根本不会执行该URLSession。查看讨论。

为什么不赌我的赛格？？只需显示。空气更新代码
