的數據似乎被加載相同的數據到每個表。我該如何解決。

您正在將相同的數據加載到控制器中的數組中，這就是爲什麼它會發生。在第一個控制器中，您正在填充數組personnelData，它包含與第二個控制器中的數組（數據dataData）相同的數據，在不同的控制器中的兩個tableview只是在數組中加載適當的值，你會得到你的輸出。 – mrugen 2011-03-29 19:18:25

您在兩個視圖中都加載了「applicationData.plist」！

如果我更改applicationData.plist的名稱，則應用程序崩潰。 – 2011-03-29 20:21:58

我已將名稱更改爲applicationDataOne.plist和applicationDataTwo.plist。似乎工作，直到我殺了應用程序，我的數據不再存在。這就像它不再向plist文件說明數據。 – 2011-03-29 20:34:30

我修正了它，我沒有使用saveData。我沒有找到saveData方法的警告，所以它返回一個類型ID。有什麼我需要添加在void語句的頭文件（saveData）？ – 2011-03-29 20:56:08
