Hi, I have a UITableView and a script that download the images from url and display them after through a NsOperation, it works but I have a doubt.
When images have already been downloaded and I do scroll up or down, my app repeat the same operations again, i.e., it downloads images from url again... and display them
Once images have already been downloaded, Must I save them to disk? so when I do scroll to get images from disk instead from url?? I have not much images in the table.
How does people make this? Any idea? Thanks
