Hi,
I am working on a small Cocoa application, which uses a TableView
to display information that is collected from an internet site. A
timer reloads the TableView every second.
The problem is that everytime the timer reloads the TableView,
about 5 - 20 MB of memory is used (depending on how many rows there
are in the tableview).
After running a while, all free memory is used on the computer, and
it begins to swap.
I have figured out that this happens due to the following conditions:
- The garbage collector is on
- A timer is used for reload
- A column contains a Check Box Cell
Ergo, the problem vanish, if I:
- turn the garbage collector off
- or reload manually
- or remove the Check Box Cell
I am a bit surprised about this, since I guess that other may have
ran into to the same problem.
Note that the program is very simple. The main window only contains
a TableView with one column, which has 10 rows. Each cell contains
a Check Box Cell.
The code is:
@implementation Controller
-(void)awakeFromNib
{
timer = [[NSTimer scheduledTimerWithTimeInterval:1 target:self
selector:@selector(timer:)
userInfo:nil repeats:YES]
retain];
}
- (int)numberOfRowsInTableView:(NSTableView *)aTableView
{
return 10;
}
-(void)timer:(NSTimer*)timer
{
[tableView reloadData];
}
@end
Thanks
Anders Lassen
