iphone - tableView viewForHeaderInSection is called N times... is this normal?

I have a tableViewController based class. I noticed that the

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
开发者_高级运维

method is called N times, where N is the number of rows the table has.

It this normal?

Wasn't the header for a section being supposed just to be drawn once for that secion? thanks

viewForHeaderInSection will be called depending on how many sections you have for your table. Try to post some more of your code, maybe from cellForIndexPathAtRow cause there's no way of really telling why you are experiencing this issue from what you have provided.
