Thanks for the tips. That thread you linked is full of great information. I'll try it this evening. I've already tried wrapping my code in a NSAutoreleasePool and that didn't do it, so I'll try using the non-convenience constructor and hope that takes care of it.

So don't do that. Do this:

NSString* results = [[NSString alloc] initWithContentsOfURL:nsURL];
[results release];

In other words, to avoid the messy unknowns of convenience constructors,
avoid convenience constructors.

Nonetheless, NSTimers when the app is in the background need autorelease
pools - in more places than you might suspect - if you are to avoid
accumulating objects until the app comes to the front. (That, as I've said
before, is the secret meaning of my .sig.) See, for example, this thread:
