Hm actually that's still off-center by a few points.

I had to change the margin constants slightly to make things center properly.

If you want to use margins that are different from the default iOS ones, you can't reuse self.textLabel.frame.origin.x.

I had a version where I used the kCellMargin constant to determine the x offset for the textLabel, but that messed up the layout once the cell is assigned an image (QuickDialog reuses part of the iOS layoutSubviews method).
