Is there a faster/easier way to loop through the NSArray of NSDictionaries and find a NSDictionary with a specific key/value?

api.json

"routes": [{
        "id": "Hillsborough Area Regional Transit_6",
        "textColor": "FFFFFF",
        "color": "09346D",
        "description": "",
        "longName": "56th Street",
        "shortName": "6",
        "type": 3,
        "agencyId": "Hillsborough Area Regional Transit",
        "url": "http://www.gohart.org/routes/hart/06.html"
    }, {
        "id": "Hillsborough Area Regional Transit_5",
        "textColor": "FFFFFF",
        "color": "09346D",
        "description": "",
        "longName": "40th Street",
        "shortName": "5",
        "type": 3,
        "agencyId": "Hillsborough Area Regional Transit",
        "url": "http://www.gohart.org/routes/hart/05.html"
    }, {
        "id": "Hillsborough Area Regional Transit_2",
        "textColor": "FFFFFF",
        "color": "09346D",
        "description": "",
        "longName": "Nebraska Avenue",
        "shortName": "2",
        "type": 3,
        "agencyId": "Hillsborough Area Regional Transit",
        "url": "http://www.gohart.org/routes/hart/02.html"
    },

loop.m

        for (NSDictionary *route in [[[tripsDict objectForKey:@"data"]
                                                 objectForKey:@"references"]
                                                 objectForKey:@"routes"])
        {
            if ([[route objectForKey:@"id"] isEqualToString:routeId]) {
                [routeName appendString:[route objectForKey:@"shortName"]];
                [routeName appendString:[route objectForKey:@"longName"]];
                break;
            }
            
        }

for (NSDictionary *route in tripsDict[@"data"][@"references"][@"routes"]
{

}

should work and you get the benefit of using literals...
