您曾經參與過你的問題是什麼是不是JSON 。它可能最初是作爲JSON數據傳輸的。但是這篇文章以屬性列表格式顯示了一個數據結構。請注意，某些字符串是HTML或XML編碼，稍後會導致問題。在將其作爲JSON傳輸之前，您應該在源處修復此問題。

現在您發佈的結果是包含更多字典的字典數組。最外面的數組是一個類別列表。每個類別都以包含其自己的名稱和ID以及子類別的字典的形式給出。最內層的字典是包含其ID和名稱的子類別。

類別字典有些問題，因爲混合兩件事情，是一個字典和數組的混合物。很難訪問子類別。

您的代碼可能會喜歡這樣：

NSArray* categoryList = [someJSONParser parse]; 
for (NSDictionary* category in categoryList) { 
    NSString* categoryName = [category objectForKey: @"cat_name"]; 
    NSNumber* categoryIdObj = [category objectForKey: @"cat_id"]; 
    int categoryId = [categoryIdObj intValue]; 

    int index = 0; 
    NSDictionary* subcategory = [category objectForKey: [NSString stringWithFormat: @"%d", index] ]; 
    while (subcategory != nil) { 
     NSString* subcategoryName = [subcategory objectForKey: @"subcat_name"]; 
     NSNumber* subcategoryIdObj = [subcategory objectForKey: @"subcat_id"]; 
     int subcategoryId = [subcategoryIdObj intValue]; 

     index++; 
     subcategory = [category objectForKey: [NSString stringWithFormat: @"%d", index] ]; 
    } 
}
