No code in debugging area for Blog reader app

I have no code in my debugging area when I run the application and I have a problem that when I click on a blog post in the table view it just takes to me to a blank screen but in my code it should take me to the treehouse blog.

I have a feeling that these might both be connected? The reason I say this is because when Amit creates an NSLog for the segue between tableViewController and webViewController it creates the output in the debug area and I can't see anything!

If someone could help it would be much appreciated.

Can you post some of your code for people to look at?

webViewController.m [super viewDidLoad]; NSURL *url = [NSURL URLWithString:@"http://blog.teamtreehouse.com"]; NSURLRequest *urlRequest = [NSURLRequest requestWithURL: url]; [self.webView loadRequest: urlRequest];


  • (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { NSLog(@"preparing for segue: %@", segue.identifier);

It will build successfully with no errors but in the simulator when I click to go through to the blog page it just comes up with a blank screen with a back button on the top left

can you post all your code for your tableView controller?

#import "BlogPost.h"

@interface TableViewController ()


@implementation TableViewController

    self = [super initWithStyle:style];

    NSURL *blogURL = [NSURL URLWithString: @"http://blog.teamtreehouse.com/api/get_recent_summary/"];

If the segue succeed I think the problem could be the webViewController.m Could you put all the code for that class as well? it seems some variable is nil as you are not getting errors
