Question

My JSON response looks like this:

    {
    "themes": [
        [
            "Direction des Routes Secteur de Pithiviers ",
            "mairies",
            "Morailles 45300 PITHIVIERS LE VIEIL ",
            "0238345744",
            "48.823042",
            "2.365907"
        ],
        [
            "Crédit Mutuel Du Centre ",
            "banques",
            "agence de Pithiviers  33 r Am Gourdon 45300 PITHIVIERS",
            "0820834080",
            "48.703042",
            "2.145907"
        ]
    ]
}

As you can see, all the Keys are unknown, i don’t have Key:value, so, how can i refer to each value.

NSDictionary *allThemesDict=[[request responseString]JSONValue];
 NSArray *allThemesValues=[allThemesDict objectForKey:@"themes"];
    for (int i=0; i<[allThemesValues count]; i++) {
        NSDictionary *currentTheme=[allThemesValues objectAtIndex:i];//here i get the first 6 values, how can i display it?
        }

They’re arrays, not dictionaries. So you can just grab the array like this:

NSDictionary *allThemesDict = [[request responseString] JSONValue];
NSArray *allThemesValues = [allThemesDict objectForKey:@"themes"];
for (int i=0; i<[allThemesValues count]; i++) {
    NSArray *currentTheme = [allThemesValues objectAtIndex:i];
    NSLog(@"currentTheme = %@", currentTheme);

    // Then access [currentTheme objectAtIndex:1] for example to get "mairies" in the first case.
}
