Question

for(id key in stats) {
    NSLog(@"key=%@ value=%@", key, [stats objectForKey:key]);
}

I have a dictionary of arrays, and each of these arrays has a number of arrays itself. Its a multidimensional array in a dictionary.

However the above code gives me the following

2012-11-30 21:36:07.203 key=main cat c value=(
"<Food: 0x6e5fb70>"
)
2012-11-30 21:36:07.205 key=main cat b value=(
"<Food: 0x6e5fa00>",
"<Food: 0x6e5faa0>"
)
2012-11-30 21:36:07.207 key=bakery_products value=(
"<Food: 0x6e5f510>",
"<Food: 0x6e5f660>",
"<Food: 0x6e5f700>",
"<Food: 0x6e5f810>",
"<Food: 0x6e5f900>",
"<Food: 0x6e5d5d0>"
)

How can I access the values in those arrays that are being displayed as Food 0x6e5fb70 ?

I’ve literally been at it for hours now and cannot find a solution.

Answer 1

Something like this perhaps:

for (id key in [stats allKeys]) {
    NSArray *foodArray = [stats objectForKey:key];
    for (Food *food in foodArray) {
        // do stuff with Food object
    }
}

Update (for Ploto’s 2nd comment):

Do you mean this:

NSArray *array = [stats objectForKey:@"bakery_products"];

Update #2 for description:

- (NSString *)description {
    return [NSString stringWithFormat:@"Food: %@, %@", whatever1, whatever2];
}
