Hi.
So I’m at crunch time and I can’t get to get this thing working. Any help would be appreciated. I have similar code that works for iOS and it works fine on the simulator, but It won’t work when I build for device.
I think the problem is that it’s not saving what is downloaded to a file like it is suppose to. Anyone know why it wouldn’t do that on the device?
Here’s my code. Basically what’s happening is I’m downloading text from an RSS feed and spitting it out into a tableView.
Thanks in advance for any help. Sorry for any extra code that doesn’t belong to this issue.
