Iphone 两个独立控制器中的两个独立UITableView，加载相同的数据

first.h

Second.h

---

数据似乎正在将相同的数据加载到每个表中。如何修复此问题。

您正在两个视图中加载“applicationData.plist”

您正在将相同的数据加载到两个控制器中的阵列中，这就是发生此情况的原因。在第一个控制器中，您正在填充阵列人员数据，其中包含与第二个控制器中的阵列（设备数据）相同的数据，因此，在不同的控制器中在两个tableview中显示相同的数据，只要在数组中加载适当的值，您就会得到输出。如果我更改applicationData.plist的名称，应用程序就会崩溃。我已将名称更改为applicationDataOne.plist和applicationDataTwo.plist。似乎有效，直到我关闭应用程序，我的数据不再存在。就像它不再向plist文件显示数据一样。我修复了它，我没有使用saveData。我注意到方法saveData未找到，因此它返回一个类型id。是否需要在void语句（saveData）的头文件中添加一些内容？
