FQL and using its result

how can we use the result that we get from F开发者_如何学编程QL

specifically how can we use the result to save it in another array take in consideration that for iOS

an example:

 NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                @"SELECT uid,name FROM user WHERE uid=4", @"query",
                                nil];
[facebook   requestWithMethodName: @"fql.query"
                         andParams: params
                     andHttpMethod: @"POST"
                       andDelegate: self];
