Question

In my table view I have 4 UIButtons, 2 in each row of table view. Initially all the buttons have an image on them (they’re hardcoded). Now there is a button in my app which when tapped replaces the images on the buttons with new ones using the setImage method and then reloads the table view. But unfortunately I am getting the old table view only i mean with old images. How can I get the new images on the buttons?

My cellForRowAtIndexPath implementation:-// Customize the appearance of table view cells.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    // if (cell == nil) {
    // cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    // }
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }

    if(indexPath.row == 0)
    {
        button1=[[UIButton alloc] initWithFrame:CGRectMake(15,5,100,87)];
        [button1 setImage:[UIImage imageNamed:@"BUTTON.png"] forState:UIControlStateNormal];
        [button1 addTarget:self action:@selector(ClickTo:) forControlEvents:UIControlEventTouchUpInside];
        [cell.contentView addSubview:self.button1];

        button2=[[UIButton alloc] initWithFrame:CGRectMake(135,5,100,87)];
        [button2 setImage:[UIImage imageNamed:@"TURN OFF.png"] forState:UIControlStateNormal];
        [button2 addTarget:self action:@selector(ClickTo:) forControlEvents:UIControlEventTouchUpInside];
        [cell.contentView addSubview:button2];
    }
    else if(indexPath.row == 1)
    {
        button3=[[UIButton alloc] initWithFrame:CGRectMake(15,5,100,87)];
        [button3 setImage:[UIImage imageNamed:@"JUMP.png"] forState:UIControlStateNormal];
        [button3 addTarget:self action:@selector(ClickTo:) forControlEvents:UIControlEventTouchUpInside];
        [cell.contentView addSubview:button3];


        button4=[[UIButton alloc] initWithFrame:CGRectMake(135,5,100,87)];
        [button4 setImage:[UIImage imageNamed:@"CLOSE.png"] forState:UIControlStateNormal];
        [button4 addTarget:self action:@selector(ClickTo:) forControlEvents:UIControlEventTouchUpInside];
        [cell.contentView addSubview:button4];
    }
    else
    {
        // Do something here
    }
    return cell;
}

You are probably setting the image for the wrong state:

[myButton setImage:[UIImage imageNamed:@"myImage.png"] forState:UIControlStateNormal];

You need to set the correct value for UIControlStateNormal – where correct means the one that matches your buttons’ current state(s).
