Description
When using
Ti.UI.SIZE for the height of a custom ListView item template, drawing the list takes up to 15x longer than using a fixed height. Obviously, calculating on the fly is expensive, but iOS offers an .automatic height attribute for the UITableViewCell which should be reused instead of calculating the height manually.
