看看这个答案http://stackoverflow.com/a/11522081/1176219 – Moonkid 2012-07-17 13:05:44

您需要为Objective-C使用JSON解析库。我会推荐JSON Framework。（现在叫做SBJson）它被广泛使用。我们一直在多个项目中使用它，取得成功并没有任何问题。

-(void)getData:(NSData*)response{ 

// You have to include the SBJSON or else you can also use the NSJSONSerialization 

//NSDictionary *jsonData   =   [NSJSONSerialization JSONObjectWithData:response options:kNilOptions error:&erro]; 

SBJSON *parse        =   [[SBJSON alloc]init]; 

NSString *jsonString      =   [[NSString alloc] initWithData:response 
                      encoding:NSUTF8StringEncoding]; 

NSDictionary *jsonData      =   [parse objectWithString:jsonString error:&erro]; 

NSArray *alldata       =   [jsonData objectForKey:@"data"]; 

if(![alldata isKindOfClass:[NSNull class]] && [alldata count] > 0) 
{ 
    for(int i = 0; i < [alldata count]; i++) 
    { 
     NSDictionary *getData    =  [allEvents objectAtIndex:i]; 

     NSString *nameString     =  [NSString stringWithFormat:@"%@",[getData objectForKey:@"name"]]; 

     NSString *idString     =  [NSString stringWithFormat:@"%@",[getData objectForKey:@"id"]]; 

    } 

} 

}

如果你没有SBJSON然后简单地取消注释与NSJSONSerialization行，并评论接下来的三使用SBJSON的行 – superGokuN 2012-07-17 13:12:36

我是JSONKit的忠实粉丝。它实现起来小得多（只是一个.h和.m文件），并且非常快速和高效。 SBJson也不错，但有很多人不需要的开销。（流，写作等）。

NSDictionary *myData = [jsonString objectFromJSONString]; 

NSString *name = [myData objectForKey:@"data"] objectForKey:@"name"]; 
NSArray *names = [myData objectForKey:@"data"]; // save all names into an array

iOS 5版本中包含JSON的API函数。在API文档中检查NSJSONSerialization。

例如为：

NSDictionary *dict = [NSJSONSerialization JSONObjectWithData: data options: kNilOptions error: error];

首先你应该添加的Json框架。带一个字典变量来加载json的响应。因为数据是字典格式。然后在数组中找到一个数组并加载该字典。然后将值存储到对象最后你得到的值
