BlogReader unrecognized selector sent to instance

Hi there,

I just finished the BlogReader project, but when I run it in the Simulator and click a table cell to load the web view, it crashes with the error "-[SBTableViewController setBlogPostURL:]: unrecognized selector sent to instance"

Depending on which code I'm using, the breakpoint goes to:

[segue.destinationViewController setBlogPostURL:blogPost.url];

or

wbc.blogPostURL = blogPost.url;

I downloaded the Treehouse project files and it runs fine. I tried looking through it to find whatever bad code I had but everything looked okay, so then I just copied all the code (everything but the Storyboard) from Treehouse's files to my files, changed the class names to match what I was using, and still got the same error.

Any ideas?

From the error it looks like you are trying to set the blogPostURL on the wrong view controller. It says SBTableViewController when it should be the view controller that contains your web view.

Thanks Amit, that helped.

Finally figured out I'd entered the wrong custom class in the IB on the view controller. Wasn't seeing that field because I kept clicking in the IB which selected children rather than the parent view controller.
