How can I delete a UITableView row on swipe? I know the question has been asked, but I get only errors. Here's the code:
-(void)tableView:(UITableView*)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath {
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath {
// If row is deleted, remove it from the list.
if (editingStyle == UITableViewCellEditingStyleDelete) {
NSInteger row = [indexPath row];
[tableDataSource removeObjectAtIndex:row];
}
}
But nothing happens. I would appreciate if you write code.

So, to remove a cell from a table view you first remove it from your data source, then you call deleteRows(at:) on your table view, providing it with an array of index paths that should be zapped. You can create index paths yourself, you just need a section and row number.
As of iOS 8.0 there's an easy way to customize the list of buttons that appear when the user swipes from right to left: editActionsForRowAt . Return an array of UITableViewRowAction objects that have titles and styles (and also background colors if you want to customize their appearance), and iOS does the rest.
When a user slides horizontally across a row the editing style of the Tabel View Cell is set to delete. When the delete button is pressed, the item is deleted in the array and also the row is deleted in the Table View. Build and run the project and swipe-to-delete a row from the Table View.
Better is just to delete the selected row, not reload all the table:
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
