UITableView insertRowsAtIndexPaths out of order
- by bschlenk
I currently have a UISegmentedControl set to add/remove table view cells when its value changes. Removing cells works perfectly, however when I insert cells they're in reverse order every other time.
NSArray *addindexes = [NSArray arrayWithObjects:[NSIndexPath indexPathForRow:2 inSection:0], [NSIndexPath indexPathForRow:3 inSection:0], [NSIndexPath indexPathForRow:4 inSection:0], nil];
NSArray *removeindexes = [NSArray arrayWithObjects:[NSIndexPath indexPathForRow:2 inSection:0], [NSIndexPath indexPathForRow:3 inSection:0], [NSIndexPath indexPathForRow:4 inSection:0], nil];
[self.tableView beginUpdates];
switch (switchType.selectedSegmentIndex) {
case 0:
[self.tableView insertRowsAtIndexPaths:addindexes withRowAnimation:UITableViewRowAnimationTop];
break;
case 1:
[self.tableView deleteRowsAtIndexPaths:removeindexes withRowAnimation:UITableViewRowAnimationTop];
break;
default:
break;
}
[self.tableView endUpdates];}
For example, every other time I add/remove cells they're in reverse order. (4, 3, 2 instead of 2, 3, 4)
1) Remove cells- add cells- correct order
2) Remove cells- add cells- incorrect order
3) Remove cells- add cells- correct order
