How to scroll to the bottom of a UITableView on the iPhone before the view appears

I have a

UITableView
that is populated with cells of a variable height. I would like the table to scroll to the bottom when the view is pushed into view.

I currently have the following function

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[log count]-1 inSection:0];
[self.table scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionBottom animated:NO];


log is a mutable array containing the objects that make up the content of each cell.

The above code works fine in
viewDidAppear
however this has the unfortunate side effect of displaying the top of the table when the view first appears and then jumping to the bottom. I would prefer it if the
table view
could be scrolled to the bottom before it appears.

I tried the scroll in
viewWillAppear
and
viewDidLoad
but in both cases the data has not been loaded into the table yet and both throw an exception.

Any guidance would be much appreciated, even if it's just a case of telling me what I have is all that is possible.

Answer

I believe that calling [table setContentOffset:CGPointMake(0, CGFLOAT_MAX)] will do what you want.
