Quick hack to enable delete menu item in UITableView menuController
- (BOOL)tableView:(UITableView *)tableView shouldShowMenuForRowAtIndexPath:(NSIndexPath *)indexPath { return YES; } - (BOOL)tableView:(UITableView *)tableView canPerformAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender { NSLog(@"%@", NSStringFromSelector(action)); return YES; } - (void)tableView:(UITableView *)tableView performAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender { }
Watch carefully, there is a problem. So you found yourself returning YES for all of the actions including the delete: selector, and the delete item just doesn't show up.
To properly fix it, you should really subclass your UITableViewCell and implement your own delete: method.
But if you would like a really quick hack for all of your default tableViewCell, you can do it with category and implements the delete: method.
After the import of snippets:
// By only returning YES for delete menu item, we can get the results like the screenshot down below. - (BOOL)tableView:(UITableView *)tableView canPerformAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender { return action == @selector(delete:); }
The category also helps you to route the delete: selector to your tableViewDelegate's tableView:performAction:forRowAtIndexPath:withSender: method, so you can handle it like all other actions.

The version you see above, I considered as a more elegant version for it's clever use of responder chain. Worth a look to the old naive version if you're digging down to the ground.
This is revised version from the old blog post.
