iphone dev - how to catch exception 'NSRangeException'
- by Brian
In my app I try to scroll a UITableView to the top once after I updated the content of the table. However, under some circumstance, my table is EMPTY. So I got the following exception:
Terminating app due to uncaught exception 'NSRangeException', reason: '-[UITableView scrollToRowAtIndexPath:atScrollPosition:animated:]: row (0) beyond bounds (0) for section (0).'
how can I catch this exception? I tried
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
if (indexPath != nil) {
[EventTable scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];
}
but it doesn't catch the exception because indexPath is not nil.
