how to get selected cells data into an array?

[vksmaini]

Hello I have a tableView which is populating from an array(tableData). there are buttons on each cell. I wanted to know how to get particular data of cell into an array when i select that cell's button and similarly how i remove it when i again select that button on cell from array? this is what iam doing till now.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
	
	static NSString *CellIdentifier = @"Cell";
	
	CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
	if (cell == nil) {
		cell = [[[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
		
	}

		// Set up the cell...
		// Configure the cell.
	if (tableView.tag == 1) {
		cell.textLabel.text = [unitArry objectAtIndex:indexPath.row];
	}
	else {
	
		
		UIImageView* img = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"g1.png"]];
		[cell setBackgroundView:img];
		[img release];
	
		cell.productLbl.text= [NSString stringWithFormat:@"%@",[[tableData objectAtIndex:indexPath.row]objectForKey:@"nameOfVegetables"] ];		
		cell.bPriceLbl.text = [NSString stringWithFormat:@"Rs %d/Kg",
											[[[tableData objectAtIndex:indexPath.row] objectForKey:@"priceOfVegetables"] intValue]]; 
	
		cell.qtyLbl.text = [NSString stringWithFormat:@"QTY: %@ %@",[[tableData objectAtIndex:indexPath.row] 
																   objectForKey:@"quantityOfVegetables"],[[tableData objectAtIndex:indexPath.row] objectForKey:@"unitOfVegetables"]] ;
		
		cell.tPriceLbl.text = [NSString stringWithFormat:@"TOTAL: %@",[[tableData objectAtIndex:indexPath.row]
																		objectForKey:@"totalPriceOfVegetables"]];
		

		BOOL selected;
		if(selected){
			
			cell.unchecked.tag=indexPath.row;
			[cell.unchecked addTarget:self action:@selector(buttonMethod:) forControlEvents:UIControlEventTouchUpInside];

		}
		//else {
//			
//			cell.unchecked.tag=indexPath.row;
//			[cell.unchecked addTarget:self action:@selector(buttonRemoveMethod:) forControlEvents:UIControlEventTouchUpInside];
//		}


		
	}
	return cell;

		
}
-(void)buttonMethod:(id)sender{

	UIButton *button =  (UIButton *)sender;
	row = button.tag;
	NSNumber *yWrapped = [NSNumber numberWithInt:row];
	
	[btnArry addObject:yWrapped];
	NSLog(@"addObjectInbtnArry:%@",btnArry);

}
-(void)buttonRemoveMethod:(id)sender{
    //????
}
//here i wanted to add all cells index to an array and fetch the data from my tableData
- (void)buy:(id)sender
{
	

	[tmpArry addObjectsFromArray:btnArry];
	

	for (id obj in btnArry) {
	
		[tableData objectAtIndex:[obj intValue]];
	}
}

plz suggest me also how to remove the particular cell index from the same array when i click on the same button again of cell.

It doesnt look like you need a buttonRemovedMethod. Instead, in your buttonMethod, add a check before you do the addObject:. Check if the array contains another NSNumber just like the one you are about to add. If it does, then remove it. Otherwise, add it.

One big assumption here is that all of your button tags are unique.
