Hi, i have a large loop that looks like this:


        for ( i = 0;  i < count; i++)
        {
                NSAutoreleasePool*      pool = [[NSAutoreleasePool alloc] init];

                NSImage*        img = [[NSImage alloc] initWithContentsOfFile:self];
                if (!img) {
                        [pool release];
                        continue;
                }

                if (img) [img release];
                img = nil;

                [pool release];
                pool = nil;
        }

Every time around the loop, memry is going up drastically and never
comes down. Am i missing something? Seems to me like the memory
should stay pretty much the same. ANy ideas?


What "memory" goes up? How are determining that memory usage is increasing?

Also the logic in you loop is rather over kill IMHO...

for ( i = 0;  i < count; i++)
{
   NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

   NSImage *img = [[[NSImage alloc] initWithContentsOfFile:self] autorelease];
   if ([img isValid]) { // or just check for not nil ... note a
message to nil is a no-op)
       ... do your stuff here ...
   }

   [pool release];
}
