Hi everyone, I'm having troubles with arrays and keys... I have an array from my database:

NSArray *elementArray = [[[menuArray valueForKey:@"meals"] valueForKey:@"recipe"] valueForKey:@"elements"]

The problem here is that I would like all my elements of all my meals of all my menus in an array such that: [elementArray objectAtIndex:0] = my first element etc... In the example above, the elements are separated by the keys. How can I get that?

Hope it's clear enough...

Thanks
