UITableView scrolls too high

[SteveMobs]

I have a UITableView with around 50 entries. There is a edit/done button that toggles the edit mode. Now, whenever edit or done is pressed I would like to scroll the list to the top.

I tried several commands dirently in the setEditing method. This works for all entries except when the focued entries were the last 2-3 in the list. In this case, the list is scroll far to high (about 5 entries) so that blank space above the table view is in view.

Actually, I was using this to scroll

[self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:YES];

but I also tried this

[self.tableView scrollRectToVisible:CGRectMake(0.0, 0.0, 1.0, 1.0) animated:YES];

(same effect)

Also, I expermented with the content offset

[self.tableView setContentOffset:CGPointMake(0.0, 0.0) animated:YES];

Nothing seems to help. If the user toggles the edit mode while table view is all the way at the bottom, the view scrolls far too high.

Does anybody have an idea what the problem is?

Thanks

Maybe the problem is that you are running on a Mapple MyPod instead of an iPod?

The first approach is what you should use. (the table view scrollToRowAtIndexPath method.) That should do exactly what you are asking for. If you manipulate the table view as a scroll view you will likely get into trouble. I've used the scrollToRowAtIndexPath call before without problems, although not in exactly the situation you describe.

It sounds to me like your table view has gotten into a bad state somehow.

Are you manipulating the table view as a scroll view elsewhere? Or mucking around with the frame/bounds of either the table view or it's container view?

Thanks for your answer.

Meanwhile, I found out that problem had something to do with the table view's footer view. In edit mode I assign a footer view and in the non-edit-mode I set the footer view to nil. So the problem was, that I was scrolling BEFORE the footer view was set to nil. I changed it and now I scroll AFTER the footer view is set to nil and everything works fine :-)
