Question

Accessing elements from a Dictionary plist

Answer 1

+1 A:

You need to call objectForKey: on the dictionary to get one of the arrays, and then call objectAtIndex:0 (or just lastObject) on the array to get the string. You can combine these two method calls into one line of code, for example:

[[dictionary objectForKey:@"All Items"] lastObject];

I think he wants them all... that's just the same as what he did except using lastObject instead of objectAtIndex:0.

I guess I need to clarify further. I'm trying to avoid using hard-coded strings like in objectForKey. The whole idea is to allow for the possibility of changing the content of the plist without having to also make a code change. What I'm trying to do with the above data is populate a table view cell.text (with the key values) and use the 'buried' string values (like 'find.png') to add an image to cell.image via UIImage imageNamed.

The reference to lastObject does help a bit, although still not the most elegant way I'd like to do this.

Then don't use an array. Use a string as a key and a string as a value. Then you can just get all the keys either through fast enumeration or the allKeys message and use objectForKey with the variable key to populate the view.

Answer 2

A:

You can use the fast enumeration of the dictionary:

for (id key in dict) {
    NSArray *array = [dict objectForKey:key];
    NSLog(@"key: %@, value: %@", key, [array objectAtIndex:0]);
}
