UITableView anchor rows to bottom

I've got a solution that works for me perfectly, but it causes a bunch of double thinking so it's not as simple in theory as it is in practice... kinda...

Step 1, apply a transform to the table view rotating it 180deg

tableView.transform = CGAffineTransformMakeRotation(-M_PI);

Step 2, rotate your raw cell 180deg in tableView:cellForRowAtIndexPath:

cell.transform = CGAffineTransformMakeRotation(M_PI);

Step 3, reverse your datasource. If you're using an NSMutableArray insert new objects at location 0 instead of using AddObject...

Now, the hard part is remembering that left is right and right is left only at the table level, so if you use

[tableView insertRowsAtIndexPaths:targetPath withRowAnimation:UITableViewRowAnimationLeft]

it now has to be

[tableView insertRowsAtIndexPaths:targetPath withRowAnimation:UITableViewRowAnimationRight]

and same for deletes, etc.

Depending on what your data store is you may have to handle that in reverse order as well...

Note: rotate the cells OPPOSITE the table, otherwise floating point innacuracy might cause the transform to get off perfect and you'll get crawlies on some graphics from time to time as you scroll... minor but annoying.

Similar approach to ima747, but rotating 180 degrees also makes the scrolling indicator go to the opposite side. Instead I flipped the table view and its cells vertically.

self.tableView.transform = CGAffineTransformMakeScale(1, -1); //in viewDidLoad

cell.transform = CGAffineTransformMakeScale(1, -1);//in tableView:cellForRowAtIndexPath:

The accepted method introduces issues for my app - the scroll bar is on wrong side, and it mangles cell separators for UITableViewStyleGrouped

To fix this use the following

tableView.transform = CGAffineTransformMakeScale (1,-1);

and

cell.contentView.transform = CGAffineTransformMakeScale (1,-1);
// if you have an accessory view
cell.accessoryView.transform = CGAffineTransformMakeScale (1,-1);
