Question

My problem is quite simple. I have some data associated to a Key. The key and data are both NSString. So the first thing which comes to my mind is to use NSDictionary.
I usually access to the value like this: [myDict objectForKey:@"myKey"];
However, sometimes I need to access to the value by index.

sample: [myDict objectAtIndex: indexPath.row]

But of course, there is no index in a Dictionary.

There are many solutions to solve this problem, but I would like to know which one is the best.

What is the best way to access to a value thanks to its key or its index ?

Answer 1

Create your custom class say DictionArray having properties of arrays and dictionaries.

Add properties NSInteger index, NSString *value etc and some methods to retrieve based on index and keys.
