字典不復制到其他字典，出現異常：詞典的說法是不是一個的NSDictionary

我使用下面的代碼：字典不復制到其他字典，出現異常：詞典的說法是不是一個的NSDictionary

NSMutableDictionary *farmGatesDict = [[NSMutableDictionary alloc] 
       initWithDictionary:[xmlDictionary objectForKey:@"FarmGates"]]; 

     NSLog(@"value from dictionary : %@", [farmGatesDict objectForKey:@"FarmGate"]); 


NSMutableDictionary *farmDetailDict=[[NSMutableDictionary alloc] 
       initWithDictionary:[farmGatesDict objectForKey:@"FarmGate"]]; 

NSLog(@"%@", farmGateString);

我使用這一點，因爲這本詞典是一個解析的XML文件，我想遍歷那個樹。我這是farmGatesDict第一代碼工作良好，但對於第二個是farmDetailDict應用是越來越有以下異常崩潰：

- [NSDictionary的initWithDictionary：copyItems：]：字典參數不是一個NSDictionary」

請建議我是我缺乏的背後..

下面是NSLog的數據...

檢查是否你的* [farmGatesDict objectForKey：@ 「出場」] *返回一個字典與否。 – spider1983

@Ashu：檢查我的答案.... –

我得到了這個問題，當我使用包含嵌套標籤和嵌套標籤時，「（」標誌即將到來，這不是起始的xml解析字典（xmlDictionary）但是我沒有解決方案可以任何人請建議的東西.. – Ashutosh

您正在獲取一個數組，從NSLog可以很容易地看到。

(
     { 
     address =   { 
      text = "\n  2873 Huon Highwway, 2km south of Huonvil

所以使用objectAtIndex:第一，然後去objectForKey:

NSMutableDictionary *farmDetailDict=[[NSMutableDictionary alloc] initWithDictionary:farmGatesDict[0]];

我沒有在我的應用程序中使用一個名爲數組的單詞，這NSLog是爲以下代碼僅用於字典NSLog（@值字典：％@「，[farmGatesDict objectForKey：@」FarmGate「]）; – Ashutosh

字典的Nslog以{開頭，而數組爲（這就是爲什麼我說它包含數組。 –

sign即將到來是因爲我是xmlDictionary，它包含來自xml文件的解析數據，並且每當嵌套標籤出現時，就會出現這個符號，並且您是正確的問題你可以建議解決方案完全一樣，因爲我不能發送代碼作爲其項目數據 – Ashutosh

看來[farmGatesDict objectForKey:@"FarmGate"]沒有返回NSDictionary。檢查它是什麼類型。

其崩潰前行只寫下面一行..

NSLog(@"value from dictionary : %@", [farmGatesDict objectForKey:@"FarmGate"]);

和發佈NSLog的結果。我敢打賭，你所得到的值不是NSDictionary。的

farmGatesDict objectForKey:@"FarmGate"]

檢查返回值嘗試NSLog它

我懷疑[xmlDictionary objectForKey:@"FarmGates"]不返回NSDictionary。

NSMutableDictionary *farmGatesDict = [[NSMutableDictionary alloc] 
       initWithDictionary:xmlDictionary];

它應該工作。
