NSDictionary objectAtIndex causing an unrecognized selector exception

I've got arrays in a NSMutableDictionary which is named favToLoad. I'm trying to get the arrays one by one with the indexPath.row of a UITableView.

Code :

NSArray* fav = [[NSArray alloc] init];
NSLog(@"IndexPath = %d", indexPath.row);
fav = [favToLoad objectAtIndex:indexPath.row];
NSLog(@"Fav = %@", fav);

The error: 

[NSCFDictionary objectAtIndex:]: unrecognized selector sent to instance

Solution

I've solved my problem by using NSMutableArray instead of NSMutableDictionary

you should use objectForKey: instead of objectAtIndex:

objectAtIndex: valid for NSArray classes

Dictionaries don't have indices. You can't do this. Instead, you need to use -objectForKey: with the appropriate key to get the value you want (you can use 'po favToLoad' in the debugger to inspect the contents).
