Instance Property


The estimated height of section headers in the table view.


var estimatedSectionHeaderHeight: CGFloat { get set }


Providing a nonnegative estimate of the height of section headers can improve the performance of loading the table view. If the table contains variable height section headers, it might be expensive to calculate all their heights when the table loads. Using estimation allows you to defer some of the cost of geometry calculation from load time to scrolling time.

The default value is automaticDimension, which means that the table view selects an estimated height to use on your behalf. Set the value to 0 to disable estimated heights.
