Prevent header from being updated after calling reloadData?

问题

I have a UITableView with a custom header that maintains some state. When I call reloadData to change/update the data in the UITableView, the header gets reloaded too. Is there any way to prevent this behavior in order to maintain state in the table's header?

回答1:

Don't put those states in the header. You've mixing the "view" with "model" in the MVC design.

Anyway, you could reload specific rows with -reloadRowsAtIndexPaths:withRowAnimation:.
