I have a UITableViewCell. I can add and subtract 1
from the cell's textLabel
and I can also delete the cells. Here is my problem, Lets say i add 5 to the value of the textLabel
. And this cell is at the 0 indexPath (The First cell in the table). When I delete this cell and there are now no longer any cells on the table, I add a new cell and this new cell automatically gets the same value as the cell that was just deleted. SO this new cell will have a value of 5
and i want the cell to have a value of 1 just like every cell should when it is added. This only happens when a cell is deleted and a new cell is added at that exact same indexPath. So my question is: do i have to delete this cells "memory" or "data" for this to be fixed? Thanks a bunch for the help!
CellForRowAtIndexPath :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
addBtn = [[UIButton alloc]init];
addBtn =[UIButton buttonWithType:UIButtonTypeRoundedRect];
[addBtn setFrame:CGRectMake(220,10,25,55)];
[addBtn addTarget:self action:@selector(addLabelText:) forControlEvents:UIControlEventTouchUpInside];
[addBtn setTitle:@"+" forState:UIControlStateNormal];
[addBtn setEnabled:YES];
[cell addSubview:addBtn];
subBtn = [[UIButton alloc]init];
subBtn=[UIButton buttonWithType:UIButtonTypeRoundedRect];
[subBtn setFrame:CGRectMake(260,10,25,55)];
[subBtn addTarget:self action:@selector(subtractLabelText:) forControlEvents:UIControlEventTouchUpInside];
[subBtn setTitle:@"-" forState:UIControlStateNormal];
[subBtn setEnabled:YES];
[cell addSubview:subBtn];
//cell.textLabel.text = @"1";
}
//cellText.hidden=!self.editing;
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
cell.imageView.image = [imageArray objectAtIndex:indexPath.row];
cell.textLabel.text = [number objectAtIndex:indexPath.row];
return cell;
}
When cells are deleted or go off screen, the table view saves them and reuses them later. So you need to reset textLabel's value in tableView:cellForRowAtIndexPath:. The UITableViewCell class reference says this:
ReplyDeleteThe table view's delegate in tableView:cellForRowAtIndexPath: should always reset all content when reusing a cell.
