How to enable swipe to delete cell in a TableView?

Question

I have a UIViewController that implements TableViews delegate and datasource protocols. Now I want to add \"swipe to delete\" gesture to cells.

Answer 1

NSMutableArray *post= [NSMutableArray alloc]initWithObject:@"1",@"2",@"3",nil]; 


- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView 
           editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {

    NSUInteger row = [indexPath row];
    NSUInteger count = [posts count];

    if (row < count) {
        return UITableViewCellEditingStyleDelete;
    } else {
        return UITableViewCellEditingStyleNone;
    }
}

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

    NSUInteger row = [indexPath row];
    NSUInteger count = [posts count];

    if (row < count) {

        [posts removeObjectAtIndex:row];
    }
}
