Creating random numbers in Objective-C for iPhone SDK

Question

I used the arc4random () function to generate a random group and sequence of numbers, but I was told that this was redundant, and I should use the random () function instead. However, the random () function gives me the same group and sequence of numbers every time.

I call srand (time (0)) once when my application starts up first to seed the random () function. Do you ever need to move the random () function?

Did I miss something?

Thanks.
