The view of your WebViewController is not initialized yet. You need to tell it to initialize. Do it after the line
WebViewController *desView = (WebViewController*) [segue destinationViewController]; }
by adding the line
[desView view];
This is the same problem as in Use destinationViewController button in a custom segue . Although this must be a very common problem, I found it hard to locate information about this.
