Question

I’m getting a little confused about when I should use a NIB file and when I should use code.
Here’s my problem :

I have a navigation based application with a RootController and its NIB file.
The RootController’s NIB file contains a TableView.
When I click on a cell I initialize a new connection with a request to load content.
When the connection has finished loading I create a new postViewController (custom) from a NIB file and I push it on the navigationController viewController stack like that :

PostViewController *postViewController = [[PostViewController alloc] initWithNibName:@"PostViewController" bundle:[NSBundle mainBundle]]; 

[postViewController.webView setDelegate:self];

postViewController.postContent = [[postsData objectForKey:@"post"] objectForKey:@"content"];

[self.navigationController pushViewController:postViewController animated:YES];

[PostViewController release];

Then, as you can see I try to set the rootViewController as the delegate for the webView in order to be able to intercept a click on a link and push a new ViewController on the stack. I need that new view to have the navigation bar with the back button.

Problem : looks like the setDelegate isn’t working because the webView:shouldStartLoadWithRequest:navigationType never gets called !

I guess I should set the delegate in the NIB file but I have no idea how. The NIB file from PostViewController doesn’t know about the RootViewController…

Here are screenshots of the NIB files :

If you need more detail just ask me.

Thanks a lot…for helping me not banging my head for another day 🙂

Answer 1

[postViewController.webView setDelegate:self]; sets the delegate for the current Controller not postViewController. Try:

[postViewController.webView setDelegate:postViewController];

And you can put this line below pushViewController:animated: then the webView should already exist.
