That did the job. It is simple:
{ // loop
  NSAutoreleasePool * loopPool = [[NSAutoreleasePool alloc] init];
  <do various things>
  [loopPool release];
}
Indeed, there were autoreleased objects created in the loop that I didn't consider.


In theory, a better way to do this would be:

NSAutoreleasePool * loopPool = [[NSAutoreleasePool alloc] init];
{  // loop
  <do various things>
  [loopPool drain];
}

But I have to admit, I recall having an issue where drain: didn't seem to work very well, so I ended up doing exactly what you did. It didn't seem to be a performance issue for me, so I didn't take the time to investigate why drain: didn't work; it bugged the crap out of me to be creating an object like that every time through the loop, but I had more pressing things to deal with.

Anyone else noticed this behavior with drain: or otherwise have an explanation? _______________________________________________
