title: Generating Random Numbers in Objective C for iPhone SDK
body: <p>I was using the arc4random() function in order to generate a random group and sequence of numbers, but I was told that this was overkill and that I should use the random() function instead. However, the random() function gives me the same group and sequence of numbers every time.</p>
  
  <p>I call srand(time(0)) once when my app first starts in order to seed the random() function. Do you ever need to reseed the random() function? </p>
  
  <p>Am I missing something?</p>
  
  <p>Thanks.</p>
