回答1:

in view will appear prepare your array which having record and in commitEditing add one line.

[self viewWillApear:YES];

and in viewWillAppear add this line

[yourTable reloadData];

after fetching data from db.

回答2:

There is little mistake (or I think the relevant code is not shown). You have deleted the entry from the database, but I think you have missed to delete the same from your array which acts as your tableview datasource.

-(void) tableView:(UITableView *)tableView
commitEditingStyle:(UITableViewCellEditingStyle)editingStyle 
forRowAtIndexPath:(NSIndexPath *)indexPath 
{
    [self.table beginUpdates];

    if (editingStyle == UITableViewCellEditingStyleDelete) 
    {   
    //  [self.table deleteRowsAtIndexPaths:[NSArray arrayWithObject: indexPath] withRowAnimation:UITableViewRowAnimationFade];
        Hadits *delHadit = [self.allBookMarks objectAtIndex:indexPath.row];
        dbAccess *dbmethods = [[dbAccess alloc] init]; 
        NSInteger delHaditid = delHadit.haditid;
        [dbmethods deleteBookMark:delHaditid];
        [dbmethods release];
        [self.allBookMarks removeObject:delHadit];/// change of code 
    }
    //[self.table reloadData];
    [table endUpdates];
}
