Question

I have the following code in a loop iterating over the different document objects:

NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init];
NSData* data = [document primitiveValueForKey:@"data"];
[document.managedObjectContext refreshObject:document mergeChanges:NO];
[pool release];

The “data” property is a large blob (a 1MB image).
And as I monitor the memory with the Allocation Instrument memory usage is increasing. I cannot find where the leak is coming from and how to remove it.

Thanks!

I managed to solve the problem by doing : [document.managedObjectContext processPendingChanges] right before draining the pool. However, I don’t understand what pending changes would be there? Could someone enlighten me on that?
