How I could to delete array of cells of my table - ios

Question

I have problem with deleting rows from table. I have a class for cell of table and a sql database. Then I loading table from database and do smth with it. Now when i try to delete rows by index paths, I have an exception.
- (void)viewDidLoad
{
[super viewDidLoad];
databasecontroller=((SexyGirlsWeatherAppDelegate *)[[UIApplication sharedApplication] delegate]).databasecontroller;
self.favorites=[databasecontroller select:#"SELECT Name, id FROM Favorites"];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
cell = (CustomCell *)[favoritesTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"CustomCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
[favoritesTableView setBackgroundColor:[UIColor clearColor]];
cell.name.text = [[favorites objectAtIndex:indexPath.row] objectForKey:#"Name"];
cell.currenttemp.text=#"+45 C";
cell.currentweather.image=[UIImage imageNamed:#"sunny"];
//[cell.selectcell setBackgroundImage:[UIImage imageNamed:#"selectfalse"] forState:UIControlStateNormal];
cell.razdelitel.image=[UIImage imageNamed:#"delenie"];
if(editModeOn==YES) [cell EditModeON];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if(editModeOn==YES)
{
int existcount=0;
for(int z=0; z<[selectrowsarray count];z++)
{
if([selectrowsarray objectAtIndex:z]==indexPath) // check for exist of item
{
[selectrowsarray removeObjectAtIndex:z];
existcount++;
}
}
if(existcount==0)
{
[selectrowsarray addObject:indexPath];
}
}
}
-(IBAction) deleteSelectedTownsFromFavorites:(id)sender // here i try to delete cells
{
// [favoritesTableView beginUpdates];
// [databasecontroller exec:[NSString stringWithFormat:#" DELETE FROM Favorites WHERE Id=%d", 3]];
// [favoritesTableView reloadData];
// [databasecontroller exec:#"UPDATE Favorites"];
// for(int t=0; t<[selectrowsarray count];t++)
// {
//
[favorites removeLastObject];
[favoritesTableView deleteRowsAtIndexPaths:selectrowsarray withRowAnimation:UITableViewRowAnimationMiddle];
// }
optionsview.hidden=true;
// [favoritesTableView endUpdates];
}
- (NSInteger)tableView:(UITableView *)favoritesTableView numberOfRowsInSection:(NSInteger)section
{
//return [favorites count];
return [favorites count];
}
How I could to synhronize 2 arrays (from database and from selectcelladdresses) for correcting deleting rows?

You also have to delete the cell from the datasource.
