Question

I’m just starting to learn Xcode, and have run in to some problems…

I’ve made a tabbed application in Xcode 4.3 which works as deired. But I previously made a simple UIWebView application, that I would now like to implement into one of the tabs on the new application.

This is what I’ve done in the classes for FirstViewController:

//  FirstViewController.h
//  SafeLine
//
//  Created by Camilla Fröberg on 2012-03-27.
//  Copyright (c) 2012 SafeLine Sweden AB. All rights reserved.
//

#import <UIKit/UIKit.h>

@interface FirstViewController : UIViewController {

    IBOutlet UIWebView *webDisplay;
}

@property(nonatomic,retain) UIWebView *webDisplay;


@end

And the FirstViewController.m:

//  FirstViewController.m
//  SafeLine
//
//  Created by Camilla Fröberg on 2012-03-27.
//  Copyright (c) 2012 SafeLine Sweden AB. All rights reserved.
//

#import "FirstViewController.h"

@interface FirstViewController ()


@end

@implementation FirstViewController
@synthesize webDisplay;

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {

    NSString *urlAddress = @"http://www.google.com";

    //Create a URL object.
    NSURL *url = [NSURL URLWithString:urlAddress];

    //URL Requst Object
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

    //Load the request in the UIWebView.
    [webDisplay loadRequest:requestObj];



    [super viewDidLoad];
}



// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return YES;
}

- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}


@end

When running the application I won’t get any error message, and it will not show the website, instead it will only show an empty view…

Any help is appreciated!

I think, you should check if you connected the UIWebView in the Interface Builder with IBOutlet.
