Randomly shuffling a number sequence

Question

I need help in randomly arranging number sequence in Obj-C for example, 1-4, it'll be 3,1,2,4 or 1,4,3,2. I know it involves this function arc4random(). Any suggestions/tips?

you can use int iRandomNum = arc4random() % 4, and use the output accordingly in for loop
