Question

My problem is whenever the user taps a button, the UITableviewcell text colors needs to change. This is my code

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath                                                                               *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    CustomCell *cell=(CustomCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if(cell==nil){
        NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
        for(id currentObject in topLevelObjects){
            if([currentObject isKindOfClass:[UITableViewCell class]]){
                cell = (CustomCell *) currentObject;
                break;
            }
        }
    }
    if(one == YES)
    {
        cell.dayLabel.textColor = [UIColor blackColor];
        cell.imageLabel.textColor = [UIColor blackColor];
        cell.high.textColor = [UIColor blackColor];
        cell.low.textColor = [UIColor blackColor];
    }
    else if(two == YES)
    {
        cell.dayLabel.textColor = [UIColor whiteColor];
        cell.imageLabel.textColor = [UIColor whiteColor];
        cell.high.textColor = [UIColor whiteColor];
        cell.low.textColor = [UIColor whiteColor];
    }
}

I reloaded in the button action, but it’s crashing when you reload.
I tried [tableview setNeedsToDisplay]; still no use…

your tableView:cellForRowAtIndexPath: is not returning a UITableViewCell.
