无法访问字典内的对象

Question

我有问题进入另一个NSDictionary内的NSDictionary。我一直在尝试访问关键nodeChildArray的第0个索引中的nodeContent键“使用设施的用户数量：163”中的文本。这是数组。

{ 
nodeAttributeArray =  (
      { 
     attributeName = class; 
     nodeContent = style1; 
    } 
); 
nodeChildArray =  (
      { 
     nodeContent = "Number of Patrons Using Facility: 163"; 
     nodeName = text; 
    }, 
      { 
     nodeName = br; 
    }, 
      { 
     nodeContent = " 
     Room Occupancy: 210 "; 
     nodeName = text; 
    }, 
      { 
     nodeName = br; 
    }, 
      { 
     nodeContent = " 
     Current Wait: 0 minutes "; 
     nodeName = text; 
    } 
); 
nodeName = p; 
} 

我曾尝试以下的不同变化：所以应该在索引中返回两个按键

//I Parse some HTML using Xpath before this 
NSArray *tutorialsNodes = [tutorialsParser  
searchWithXPathQuery:tutorialsXpathQueryString]; 

NSDictionary*dict=[tutorialsNodes objectAtIndex:0]; 
NSDictionary*dict2=[[dict objectForKey:@"nodeChildArray"]objectAtIndex:0]; 

但它一直返回null。我真的很感谢一些帮助。谢谢！

MainResultDictionary =>包含您回应

你应该在代码

NSArray *dictsArr = [MainResultDictionary objectForkey:@"nodeChildArray"]; 
NSdictionary *dict = [dictsArr objectAtIndex:0]; 
[dict objectForkey:@"nodeContent"];
