I want to create an array of numbers from 0-9 and want them to be randomized
Meaning, when a user clicks on a UIButton it creates an NSMutableArray of objects 4,5,8,3,6,
As per this SO answer whats-the-best-way-to-shuffle-an-nsmutablearray, just create your list of numbers 0..9, (or 0..1000, whatever) in a mutable array and then randomly shuffle them.
