Question

So I have the following header of a tableview:

UITableViewHeaderFooterView* header =[self.tableView headerViewForSection:0];

This header has an imageview which I added programatically as a subview. How can I modify and reload this image or anything in header, without having to do a [tableView reloadData]?

Answer 1

I Think u can enumerate on the subviews of header like this:

UITableViewHeaderFooterView* header =[self.tableView headerViewForSection:0];
for(UIView *v in header.subviews){
    if([v isKindOfClass:[UIImageView class]])
         {
           UIImageView *imgView = (UImageView*)v;
           //do ur stuff here for modification
            break;
         }   
    }

if u have multiple ImageViews u can differ between them with tag
