问题
I have a Storyboard which contains a UITableViewController. The table view is static and contains two sections. The table view was setup entirely in IB (including the header and footer text of the table view sections) - I have not implemented any table view delegate methods in my view controller.
If I attempt to get a reference to the UITableViewHeaderFooterView for a given section it always returns nil.
UITableViewHeaderFooterView* header =[self.tableView headerViewForSection:0];
When I run the app I can see the header and footer text that I set in IB so I know those views are there. I just can't figure out how to access them programmatically.
Any help would be much appreciated, CS

Actually you'll need to specify the table footer view, and pass it to the table view using its delegate.
For example, suppose you have defined a IBOutlet UIView named tableFooterView. Then in the following delegate method, you can pass your tableFooterView to your table view:
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section; // custom view for footer. will be adjusted to default or specified footer height
{
return self.tableFooterView;
}
Also you'll need to implement the following method to set the height of the table footer view:
-(CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
{
return self.tableFooterView.frame.size.height;
}
