how to play random sound without repeat ?after playing all file then again start new cycle of sound

Question

I want to play sound in randomly without repeating at once time.All sound played after again start new cycle of random sound.

For Example:we have 5 file.

start random playing:3,1,5,2,4(this is right)--- 3,1,3,5,2,4(this is wrong)

Answer 1

Conceptually this is how I would approach this problem

• Store all your sounds into an array
• randomize your array
• Store that array into a nsuserdefaults. So that in case user closes and relaunches app then you still have that randomized array
• count how many sounds have been played. Store the count into a nsuserdefaults as well. (for same reason as above)
• Now once the count reaches array count then randomize the array again and start all over.

Kinda makes sense?
