Access random items from an array in the iPhone SDK

Question

I want to know how to access random items from array in the iPhone SDK?

I have made a music player in which the next song comes from array on button-click, but I want to get the songs randomly.

Answer 1

You can use the rand() function:

NSInteger randomIndex = rand () % [list count];
Thing * randomThing = [list objectAtIndex:randomIndex];

Don't forget to call srand(unsigned int seed) on startup:

srand(time(0));
