How to animate the height change of an section header in UITableView?

Question

I\'ve implemented this method to return the section header height. However, when the height for the section changes, it happens immediately without animation.

Answer 1

I haven't tested this, but sometimes I get unwanted animations when my UITableViewCells change height. The cause of this is that I draw my own cells, and I use CALayers to do so. In the cell's (void)layoutSubviews I would change the size of my CALayer to be the size of the frame for the cell

myLayer.frame = self.bounds;

When the frame/bounds property of a CALayer changes, it is animated. So in theory, I would say that you could use the method tableView:viewForHeaderInSection: which would allow you to draw your own section header. You could just return a UIView that implements (void)layoutSubviews and then in that method do

self.layer.frame = self.bounds;

Just an idea.
