Question

I am using two NSMutable Arrays for storing multiple checkmarks..repeatDaysToStore and data1.
This is the code in viewDidLoad method…

for (int i=1; i<=[repeatDaysToStore count]; i++) 


{

    BOOL isTheObjectThere = [repeatArray containsObject:[repeatDaysToStore objectAtIndex:(i-1)]];

    if (isTheObjectThere) 
    {

        NSString *into=[repeatArray objectAtIndex:[repeatArray indexOfObject:[repeatDaysToStore objectAtIndex:(i-1)]]];


              [data1 addObject:into];

        NSLog(@"check did load");

    }



}

and after this I am using data1 array for checking the cells…

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:                  (NSIndexPath *)indexPath
 {
    static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
 if (cell == nil) {

    cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault   reuseIdentifier:CellIdentifier];
 }
 cell.textLabel.text=[repeatArray objectAtIndex:indexPath.row];
tableView.allowsMultipleSelection=YES;
 for (int j=1; j<=[data1 count]; j++) {
     NSLog(@"%d",[[data1 objectAtIndex:(j-1)]intValue]);
       NSLog(@"%d",indexPath.row);
   if([data1 indexOfObject:[data1 objectAtIndex:(j-1)]]==indexPath.row)
     {
  cell.accessoryType = UITableViewCellAccessoryCheckmark;
 } 
 else
  {
       cell.accessoryType = UITableViewCellAccessoryNone;
  }

  }

and for handling row selections I am using this code in didSelectRowAtIndexPath
{
NSString *myobj=[repeatArray objectAtIndex:indexPath.row];

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];    
      if (cell.accessoryType == UITableViewCellAccessoryCheckmark) {
        cell.accessoryType = UITableViewCellAccessoryNone;
        [repeatDaysToStore removeObject:myobj];
        [data1 removeObject:myobj];


    } else {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
        [repeatDaysToStore addObject:myobj];
        [data1 addObject:myobj];

    }
[tableView reloadData];
 }

but its not working.Someone please tell me what is wrong?

I think the issue is with cellForRowAtIndexPath: method’s following code:

for (int j=1; j<=[data1 count]; j++)
{
     NSLog(@"%d",[[data1 objectAtIndex:(j-1)]intValue]);
     NSLog(@"%d",indexPath.row);
   if([data1 indexOfObject:[data1 objectAtIndex:(j-1)]]==indexPath.row)
   {
     cell.accessoryType = UITableViewCellAccessoryCheckmark;
   } 
   else
   {
       cell.accessoryType = UITableViewCellAccessoryNone;
   }
}

Remove the code and write the condition like:

if([data1 containsObject:[repeatArray objectAtIndex:indexPath.row])
{
   cell.accessoryType = UITableViewCellAccessoryCheckmark;
} 
else
{
   cell.accessoryType = UITableViewCellAccessoryNone;
}

Also remove the [tableView reloadData]; from didSelectRowAtIndexPath:
