Question

我从我的网络服务器返回了以下JSON对象。我无法弄清楚如何解析它......我基本上想要为每个驱动程序提取uname和profilePic（在这个例子中有两个驱动程序）。我对其他东西不感兴趣。

这是JSON：

{
    "0": {
        "uname": "Eamorr",
        "fname": "Bill",
        "lname": "Byrne",
        "phoneNumber": "087-2342404",
        "roofSignNumber": "32984",
        "reputation": 0,
        "vehicleMake": "Toyota",
        "vehicleModel": "Carina",
        "vehicleNumPassengers": "4",
        "profilePic": "XE7F654O05RC3I33P44A",
        "online": 1,
        "lat": "52.27114461",
        "lng": "-9.70294471",
        "status": "done!",
        "sex": "M",
        "picList": ["W725CY1XR63PW480Z694", "XBA2078W4Z3JROQMSN16", "0H0XDD27J9J9RV28KKR4", "84G09NCP537G1KM6O4R8", "FM12F2J12AWL8C8XX2F5", "5AU4FLJ50PN0R210AP8J", "5588ORG95RF10B757NY7", "4z54cz5c565410r2wq2u", "3502IXTI31MSX6Z01NWC", "XE7F654O05RC3I33P44A", "A828K8M0E5576C1AK6HU", "M5EHX8MQMHZ6PJ1NNYH7", "8RIS3245542E2I9TLOD4", "3V5F7HNZNN642O29347Y", "YU2CT34A7769XG2LV38G"],
        "last5comments": [{
            "comment": "asdf2",
            "fromUname": "Anonymous",
            "time": 1314036666
        }, {
            "comment": "qwerty",
            "fromUname": "Eamorr",
            "time": 1314550970
        }, {
            "comment": "qwerty",
            "fromUname": "Eamorr",
            "time": 1314551143
        }, {
            "comment": "hi",
            "fromUname": "Eamorr2",
            "time": 1315157494
        }, {
            "comment": "Hello",
            "fromUname": "Anonymous",
            "time": 1315394983
        }],
        "numPagesComments": 13
    },
    "1": {
        "uname": "Eamorr2",
        "fname": "Steve",
        "lname": "McCloskey",
        "phoneNumber": "087-3234404",
        "roofSignNumber": "32431",
        "reputation": 0,
        "vehicleMake": "Toyota",
        "vehicleModel": "avensis",
        "vehicleNumPassengers": "4",
        "profilePic": -1,
        "online": "0",
        "lat": "52.28783634",
        "lng": "-9.66791791",
        "status": "",
        "sex": "M",
        "picList": [],
        "last5comments": [{
            "comment": "asdf",
            "fromUname": "Anonymous",
            "time": 1296655686
        }, {
            "comment": "I'm off in the middle of the Atlantic again",
            "fromUname": "Anonymous",
            "time": 1296843759
        }, {
            "comment": "Hi",
            "fromUname": "Eamorr",
            "time": 1299098148
        }, {
            "comment": "Hi",
            "fromUname": "Eamorr",
            "time": 1299098148
        }, {
            "comment": "Hi",
            "fromUname": "Eamorr",
            "time": 1299098148
        }],
        "numPagesComments": 2
    }
}

这就是我试图编写的代码（无济于事......）：

//NSDictionary *obj=[parser objectWithString:[request responseString] error:nil];
        NSArray *obj=[parser objectWithString:[request responseString] error:nil];

        NSLog([obj objectAtIndex:0]);
        /*for(int i=0;i<obj.count;i++){
            NSDictionary *driver=[obj objectAtIndex:i];
            for (NSDictionary *dict in driver) {
                [unames addObject:[dict objectForKey:@"uname"]];
                [profilePics addObject:[dict objectForKey:@"profilePic"]];
            }
        }

我希望有人可以提供帮助。

解决方案：

SBJsonParser *parser=[[SBJsonParser alloc]init];
        //NSDictionary *obj=[parser objectWithString:[request responseString] error:nil];
        NSDictionary *obj=[parser objectWithString:[request responseString] error:nil];

        for(int i=0;i<[obj count];i++){
            NSDictionary *obj2=[obj objectForKey:[NSString stringWithFormat:@"%d",i]];
             NSLog(@"%@",[obj2 objectForKey:@"uname"]);
        }

使用SBJSON https://github.com/stig/json-framework

SBJSON *jsonReader = [[[SBJSON alloc] init] autorelease];
NSDictionary *responce = [jsonReader objectWithString:[request responseString]];

NSString *uName1 = [[responce objectForKey:@"0"] objectForKey:@"uname"];
NSString *image1 = [[responce objectForKey:@"0"] objectForKey:@"profilePic"];

Objective-C：帮我解析这个JSON
