Question

This question is bit related to my earlier question

I am newbie for iPhone application and trying to learn UITableView with JSON. I followed this video for learning.

I created same example using Stoaryboard and also added new screen where I can add data. Now I was trying to delete the data. So what I did is thought is instead of below method, I will add button on each row and on clicking of that I will delete the data.

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath

But I am not getting how I will get the row details and how to delete.

Any help/ suggestion would be grateful.

Below is how my screen looks like.

Note:

The UITableViewCell is of CUSTOM type.

Answer 1

Update the data model according to edit actions delete using bellow code.

This bellow code is just an example for hot to delete or remove the object from array and also from table .. for more info check the tutorial which i post the link bellow..

- (void)tableView:(UITableView *)aTableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

     if (editingStyle == UITableViewCellEditingStyleDelete) {

         [arryData removeObjectAtIndex:indexPath.row];

        [tblSimpleTable reloadData];

     } 
}

or also using this bellow logic with custom button of cell…

- (IBAction)deleteCustomCellWithUIButton:(id)sender
{
  NSIndexPath *indexPath = [yourTableView indexPathForCell:(UITableViewCell *)[[[sender superview] superview] superview]];
  NSUInteger row = [indexPath row];
  [yourTableView removeObjectAtIndex:row];
  [yourTableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]  withRowAnimation:UITableViewRowAnimationFade];
}
