                  {
            address = "256, Road Number 19, Wadla Village, Vadala, Mumbai, Maharashtra 400031, India";
            "address_id" = 49;
            "address_title" = dsa;
            "building_name" = das;
            latitude = "19.01761470";
            longitude = "72.85616440";
            "user_id" = 13;
        }
    );
}

I'm trying to retrive data from the JSON dictionary. I need to fetch the datas in address from the Address dictionary and store it in an array . My Array should look like this : [Bengaluru, Karnataka 560008, India,Bengaluru, Karnataka 560008, India,Bengaluru, Karnataka 560008, India,256, Road Number 19, Wadla Village, Vadala, Mumbai, Maharashtra 400031, India]

Need help please .

Have you checked the nsjsonserialization Class and it's methods? — YYfim, Feb 03 '15 at 12:33
Well, wouldn't you just create an NSMutableArray and add to it whatever you want from the dictionary? — gnasher729, Feb 03 '15 at 12:44
As I can see,Your JSON array is not correct. double quotes are missing for address and semicolon shouldn't be there in JSON Array. — Sushil Sharma, Feb 04 '15 at 05:06

Filtering NSDictionary with predicate

You can filter an NSDictionary with an NSPredicate.

Assuming your dictionary is NSDictionary *dict

NSArray *resultArray = [[dict objectForKey:@"Address" allValues] filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"(key == %@)", @"address"]];

NSMutableArray *resultArray = [NSMutableArray new];   
NSError *jsonError = [[NSError alloc] init];
NSDictionary *pR = [NSJSONSerialization JSONObjectWithData:yourJsonObject options:NSJSONReadingAllowFragments error:&jsonError];
NSArray *pArray = pR[@"Address"];

for(NSDictionary *dict in pR)
{
    [resultArray addObject:dict[@"address"]];
}
