I didn't even wait that long, it was running ridiculously slow in my
comp already after 25000 runs. You realize none of these objects get
deallocated while you are in this loop? This amounts to 100.000 NSDate
objects sitting around in memory....

Hey Folks,
I am working on a project where I have to load up a bunch of
information categorized by dates. The dates are in a natural language
format "mm/dd/yyyy" and need to be turned into NSDate objects so I can
work with them.
The number of items that are being loaded is rather large. Easily Half
a million plus.
When I run the program after about 100,000
NSDate * thisDate = [NSDate dateWithNaturalLanguageString:theDate];
the app goes boom and I get an EXC_BAD_ACCESS error.
I thought this might have been from bad memory management (it still
might be, as I am *very* new to cocoa development) so I created a
simple test app with a button that run this function.
@implementation test
- (IBAction)run:(id)sender
{
int i;
for (i=0; i<500000; i++)
{
NSDate * thisDate = [NSDate
dateWithNaturalLanguageString:@"12/14/2004"];
NSLog(@"%d", i);
}
}
@end
After running through about 100,000 of these (give or take) I get the
exact same error.
My questions are:
Given the error is an EXC_BAD_ACCESS error am I doing something wrong
memory management wise?
If not, any idea what is causing this?
And more to the point... any ideas on how I can fix this? Or how I can
work around it?
Thanks Much,
Kane
