Let's say that I'm doing something similar in design, to a file
browser, with an outline view. Basically, there may be a large number
of hierarchical data, which may be more than I want to store in the RAM.
The outlineview, being datasource driven, is a great design for this.
However, I don't really get a great feedback on when to release my
nodes. Let's say that I create on demand, some nodes to return from
outlineView:child:ofItem: . Now, the RAM required by my app, has
risen. However, the RAM required to display what is on screen might
not have risen, as the size of an outlineview is finite (and won't
display too many rows at once).
So, then I must need some kind of way to release nodes that are not
in use by the outlineview.
So how do I make sure my RAM doesn't bloat?
Is the only solution to periodically call [outlineView reloadData];
(and previously release all my node data)?
