objective c - NSDictionary to NSArray?

i have a NSDictionary which looks like:

{
"Item1" = 2.4;
"Item2" = 5.5;
"Item3" = 15.6;
}

To use this NSDictionary Items in a Table View i have to transfer it to a NSArray, am i right?

So i try:

NSDictionary *dict = [myDict objectForKey:@"items"];

for (id item in dict) {
    [_myArray addObject:[dict objectForKey:item]];
}

But _myArray keeps empty? What am i doing wrong?
