UITableViewCell not showing until scrolling

Question

I'm having an issue where my UITableViewCell's image (I customized it into a cell with just the image) is not showing up after being downloaded unless you have scrolled down to make it invisible and scroll up to see again.

I am using HJCache for asynchronous image downloading as well as caching. What I am not sure is if this was the issue with HJCache or my UITableViewCell and how to fix it.

If you are using blocks, this solution will work- http://stackoverflow.com/a/17166033/2082569 — atulkhatri, Nov 26 '13 at 06:56

When the image has finished downloading (assuming the cell itself is the delegate for the asynchronous call), call [self setNeedsDisplay] which will redraw the cell. This is what happens when the cell is reloaded because of scrolling.

Well, I'm just going to answer my own question since I had found the most ridiculous solution.

After trying out various methods and headaches, I deleted the app ( + cache) from the simulator and everything seems to be working properly again.

My best guess is that the locally stored unfinished images by HJCache were messing up.

As soon as your data is finished loading, call [tableView reloadData]; This will make the tableView reload all of it's cells that are currently visible.

The data is already downloaded because I can already see some cells with just the background. – Ye Myat Min Feb 02 '11 at 10:17
Just see if calling the method I suggested fixes your problem. – Aurum Aquila Feb 02 '11 at 10:27

Nope. It doesn't. All the views that are not visible are loaded properly. – Ye Myat Min Feb 02 '11 at 10:41
Thanks, calling ReloadData() after binding tableView helped me. – Rusted Mar 01 '13 at 13:22

When you set up the cell set the image to nil. If that doesn't work set the image to a default locally stored image of the same size web if it's just completely white.
