You are getting Array of Dictionary in response, but your response is in string so you convert it to NSArray using NSJSONSerialization like this way for that convert your response string to NSData and after that use that data with JSONObjectWithData: to get array from it.

NSString *jsonString = @"[{\"VisitorID\":\"2864983a-e26b-441a-aedf-84e2a1770b8e\",\"ProfileID\":\"69c02265-abca-4716-8a2f-ac5d642f876a\",\"CompanyID\":null,\"VisitorName\":\"kanasalingam\",\"OperatorName\":\"baman\",\"Image\":null,\"isocode\":\"lk\",\"CurrentOperator\":[\"69c02265-abca-4716-8a2f-ac5d642f876a\"]},{\"VisitorID\":\"133bc108-b3bf-468a-9397-e1b0dba449db\",\"ProfileID\":\"69c02265-abca-4716-8a2f-ac5d642f876a\",\"CompanyID\":null,\"VisitorName\":\"kumar\",\"OperatorName\":\"baman\",\"Image\":null,\"isocode\":\"lk\",\"CurrentOperator\":[\"69c02265-abca-4716-8a2f-ac5d642f876a\"]}]";
NSData *data = [jsonString dataUsingEncoding:NSUTF8StringEncoding];

NSError *e;
NSMutableArray *jsonArray = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&e];

Now loop through the array and access the each dictionary from it.

for (NSDictionary *dic in jsonArray) {
     NSLog(@"%@",[dic objectForKey:@"VisitorID"]);
     ... and so on.
}
