UITableView reload section

Question

I want to reload only one section not the full table. Is there any method in UITableView.

[tableView reloadData] is used to load full table

Answer 1

The reloadSections method bugs me -- as I have to construct a few objects. This is great if you need the flexibility, but sometimes I also just want the simplicity too. It goes like this:

NSRange range = NSMakeRange(0, 1);
NSIndexSet *section = [NSIndexSet indexSetWithIndexesInRange:range];                                     
[self.tableView reloadSections:section withRowAnimation:UITableViewRowAnimationNone];

This will reload the first section. I prefer to have a category on UITableView and just call this method:

[self.tableView reloadSectionDU:0 withRowAnimation:UITableViewRowAnimationNone];

My category method looks like this:

@implementation UITableView (DUExtensions)

- (void) reloadSectionDU:(NSInteger)section withRowAnimation:(UITableViewRowAnimation)rowAnimation {
    NSRange range = NSMakeRange(section, 1);
    NSIndexSet *sectionToReload = [NSIndexSet indexSetWithIndexesInRange:range];                                     
    [self reloadSections:sectionToReload withRowAnimation:rowAnimation];
}
