- [__ NSCFArray objectAtIndex：]：指數（1）超出範圍（1）

任何事情之前，我的plist之前我添加項目1和項目2- [__ NSCFArray objectAtIndex：]：指數（1）超出範圍（1）

然後作爲項目工作的精細與下面的代碼進步，我必須在我的plist中添加幾個項目。然後發生錯誤。

的問題是，我有了項0，第1項，第2項爲字典如所述下方的「根」的plist：順便

的的Plist具有除了在串相同的數據省。

而不是顯示plist中表現出一定的實際陣列，luzonRegion的 - 這將是更加有用。另外，什麼行會拋出錯誤？ – rdelmar

我已經添加了luzonRegion的實際數組。該項目有沒有問題，而是，這一個：http://f.cl.ly/items/233S423H081o290u3W0L/Screen%20Shot%202012-12-17%20at%2011.15.51%20AM.png – Jahm

我的意思是顯示結果的NSLog（@「％@」，luzonRegion），而不是pList。 – rdelmar

這個問題似乎是在這裏：

NSDictionary *luzonDictionary = [luzonRegion objectAtIndex:indexPath.row]; 
NSDictionary *visayasDictionary = [visayasRegion objectAtIndex:indexPath.row]; 
NSDictionary *mindanaoDictionary = [mindanaoRegion objectAtIndex:indexPath.row];

如果其中一個區域不會包含儘可能多的項目作爲其他地區，這將失敗。

是的，我注意到了。我在luzonDictionary中有2個項目，在visayasDictionary中有4個，在mindanaoDictionary中有3個項目。先生，我該如何解決這個問題？ – Jahm

寫出類似於情況0的東西： cell.textLabel.text = [[luzonRegion objectAtIndex：indexPath.row] objectForKey：@「Province」]; 休息; –

我找到了！在cellForRowAtIndexPath中，就像Nickolay O.所說的那樣！

我把它改爲：

switch (indexPath.section) { 
    case 0: 
     cell.textLabel.text = [[luzonRegion objectAtIndex: indexPath.row] objectForKey: @"Province"]; 
     break; 

    case 1: 
     cell.textLabel.text = [[visayasRegion objectAtIndex: indexPath.row] objectForKey: @"Province"]; 
     break; 

    case 2: 
     cell.textLabel.text = [[mindanaoRegion objectAtIndex: indexPath.row] objectForKey: @"Province"]; 
     break; 

    default: 
     break; 
}
