  1. POiphone development: changing the button image on tableviewcell
    text
    copied!<p>In my app I am facing with a really weird problem. I am trying to solve it for hours but could not find what is the problem so far. </p> <p>Well, I have a tableview with custom cells. and each cell I have a button. It is is like an empty box. When the button pressed, I want to change the related cell image of that button. Actually I successfully do that but somehow, some other cell's button images are also changing and I could not figure out why. Here is my code:</p> <pre><code> - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"cell"; CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { //create new cell cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } [cell.tickButton setTag:indexPath.row]; [cell.tickButton addTarget:self action:@selector(buttonWasPressed:)forControlEvents:UIControlEventTouchUpInside]; //cell has 2 label so I filled them with the contents of my object array that part is working with no problem cell.leftLabel.text = [NSString stringWithFormat:@"%@", [[contacts objectAtIndex:indexPath.row]name]]; cell.rightLabel.text = [NSString stringWithFormat:@"%@", [[contacts objectAtIndex:indexPath.row]email]]; return cell; } </code></pre> <p>in my buttonWasPressed method I simply do:</p> <pre><code>-(IBAction)buttonWasPressed:(id)sender { UIButton *button = (UIButton *)sender; [button setImage:[UIImage imageNamed:@"ticck.jpeg"] forState:UIControlStateNormal]; } </code></pre> <p>As I said before it works but also changes some other buttons images and also when I scroll down and get back to the initial position I see that some button images are changed.</p>
