Question

I am using AQGridView for a grid of images.I need to overlay a progress bar over a particular image which is being downloaded. The problem is, if I scroll that Image cell out of view, the progress bar appears on another cell as well. I think this is because cell is being reused.

Is there a way i can mark certain cells from being reused?

Please don’t do that. You should update your cell in - gridView:cellForItemAtIndex:, which gets called for every cell that becomes visible.

Something like:

- (AQGridViewCell *)gridView:(AQGridView *)aGridView cellForItemAtIndex:(NSUInteger)index
{
     AQGridViewCell *cell;

     // dequeue cell or create if nil
     // ...

     MyItem *item = [items objectAtIndex:index];
     cell.progressView.hidden = !item.downloading;

     return cell;
}
