Use a local autorelease pool, like this:
- (IBAction)Generate:(id)sender
{
// some code
for (i = 0; i < count; i++) {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSImage *tempSource = [NSImage imageWithContentsOfFile:sPath[i]];
// some code
[pool release];
}
}

Hi everybody,
I am writing an application where, at some point in time, the user
clicks a button and for a great amount of images the average pixel
values are calculated and stored in an array.
Basically this looks like this:
-(IBAction)Generate:(id)sender
{
// some code
for (i = 0; i < count; i++)
{
NSImage* tempSource = [[NSImage alloc] initWithContentsOfFile:sPath
[i]];
// some code
[tempSource release];
}
}
When debugging with ObjectAlloc i found that the memory release
does not happen when the release message is sent but only after the
Generate function is done. So instead of allocating, deallocating,
allocating, deallocating... the application keeps allocating memory
and only releases it afterwards. This becomes a big problem when
the amount of loaded pictures rises. Is there a way to force the
memory manager to free the memory when the release message is sent
instead of after the call? Or can i solve this problem in another way?
Thank you very much,
Yannick, Belgium
