dictionary consist of objects and keys which are array if you successfully try to gets keys and objects may be you will be able to map NSMutableDictionary into NsMutableArray — Leena, Dec 12 '11 at 05:34

Did you look at the console to find out *why* it's crashing? I'll bet you get a message there that says `dict` does not respond to the selector `-objectAtIndex:`. Dictionaries are not arrays, and NSDictionary doesn't provide a `-objectAtIndex:` method. — Caleb, Dec 12 '11 at 05:35
I don't understand what you are trying to do. The code you've got is completely wrong. I see you've got a `dict` variable and an `array_listToDisplay` variable. Which objects in `dict` do you want to add to the array? — Abhi Beckert, Dec 12 '11 at 06:00

Do you want the dictionary's keys, or the dictionary's values?

NSMutableArray *keys = [NSMutableArray arrayWithArray:[dict allKeys]];
NSMutableArray *values = [NSMutableArray arrayWithArray:[dict allValues]];

If you're trying to add all the objects in the dictionary to the array, you just do this:

[array_listToDisplay addObjectsFromArray:[dict allValues]];
