A dictionary is an unsorted collection.

You should really look at putting the dictionaries or just the keys into an array.

Then you can use the array for sorting and the keys to reference the dictionary.

use NSMutableArray for keys and add a key to that NSMutableArray each time you add photo to the dictionary. The array will keep order
