Extracting data from multidimensional NSMutableArray into a simpler array

I'm learning iOS but have an issue extracting data from a multidimensional NSMutableArray, I've looked at various solutions but have not yet found one..

I have an NSMutableArray like

{
 "service_0" = {
    "name" = "name1";
    "description" = "description1";
};
 "service_2" = {
    "name" = "name2";
    "description" = "description2";
};
Etc...
}

I wish to extract data into a new NSMutableArray (or NSArray) to get the following output for use in text labels such as = [myArray objectAtIndex:indexPath.row] 

(
    name1,
    name2,
Etc...
)

What would be the best solution? Thanks

Assuming that is an array of dictionaries, unlike in the question...

NSArray *newArray = [oldArray valueForKeypath:@"name"];

You can make it mutable using mutableCopy, if you wish.
