title: Should I -drain or -release an autorelease pool in iPhone OS?
body: <p>The doc says:</p>
  
  <blockquote>
    <p>In a garbage-collected environment,
    sending a drain message to a pool
    triggers garbage collection if
    necessary; release, however, is a
    no-op. In a reference-counted
    environment, drain has the same effect
    as release. Typically, therefore, you
    should use drain instead of release.</p>
  </blockquote>
  
  <p>If I get that right, they say that I should always use -drain, doesn't matter if there's Garbage Collection around or Reference Counting. On iPhone is no GC, so anyways I send -drain?</p>
  
  <p>Unfortunately, the doc only talked about Cocoa, not Cocoa Touch or iPhone. So I am not sure if the same applies there.</p>
