解析JSON字典/陣列

Question

如果一個JSON Web服務將返回這樣的事情（房屋的詳細信息）

[ 
    { 
     id:4, 
     price: 471, 
     location: "New York", 
     size: 3000 
    }, 
    { 
     id:7, 
     price: 432, 
     location: "London", 
     size: 3200 
    }, 
    { 
     id:22, 
     price: 528, 
     location: "Tokyo", 
     size: 2000 
    } 
] 

我怎麼會遍歷直通每家一個接一個？我使用ASIHTTPRequest和JSON解析器：http://stig.github.com/json-framework/

我想我可以得到字典，像這樣：

NSString *theResponse = [request responseString]; 
NSDictionary *dictionary = [theResponse JSONValue]; 

..但我不能確定如何遍歷每個直通房子。

{ 
     id:4, 
     price: 471, 
     location: "New York", 
     size: 3000 
    }, 
    { 
     id:7, 
     price: 432, 
     location: "London", 
     size: 3200 
    }, 
    { 
     id:22, 
     price: 528, 
     location: "Tokyo", 
     size: 2000 
    } 

這是字典的陣列...你可以創建一個模式類的，你家（歸屬：ID，價格，位置，大小），如下重複它......（考慮你終於有上述事情）..

NSArray *houses = [dictionary objectForKey:<youHaveNotProvideItInYourData>]; 
NSMutableArray *populatedHouseArray = [[NSMutableArray alloc]init]; 
for(int i=0;i<[houses count];i++) 
{ 
    NSDictionary *tempDictionary = [houses objectAtIndex:i]; 
    House *tempHouse = [[House alloc]init]; 
    if([tempDictionary objectForKey:@"id"]!=nil 
    { 
    tempHouse.id = [tempDictionary objectForKey:@"id"]; 
    } 
    //and so on for other keys 

    [populatedHouseArray addObject:tempHouse]; 
    [tempHouse release]; 
}
