If this is the exact code you're using then it can't work: the webView added to topView that is never put on screen anywhere.
You probably want to add the webView to the controller view, but a better place to do that might be viewDidLoad, where self.view can be used safely.
This code works for me:
- (void)viewDidLoad {
[super viewDidLoad];
self.webView = [[[UIWebView alloc]
initWithFrame:CGRectMake(0, 0, 320, 480)] autorelease];
NSString *urlAddress = #"http://www.google.com";
NSURL *url = [[[NSURL alloc] initWithString:urlAddress] autorelease];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:requestObj];
[self.view addSubview:self.webView];
}

Using the Storyboard -
Step 1: Drag and drop a UIWebView in the View
Step 2: Then go to the .h file (for that particular view) and create an IBOutlet of a UIWebView. For example-
// MainViewController.h
#interface MainViewController : UIViewController
#property (nonatomic, strong) IBOutlet UIWebView *myWebView;
#end
Step 3: Go to the storyboard and create a connection from outlet, myWebView (This can be found in the inspector area of Xcode) to the UIWebView by doing a control drag.
Step 4: Now when we have the connection, we just need to go to the .m (for that particular view) and add the following code -
//MainViewController.m
#implementation MainViewController
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *urlNameInString = #"https://www.google.com";
NSURL *url = [NSURL URLWithString:urlNameInString];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
[self.myWebView loadRequest:urlRequest];
}
#end

Here is My Solution.
Create a ViewController with WebView in Interface Builder and connect webview as IBOutlet
This code is simple and works fine
- (void)viewDidLoad
{
[super viewDidLoad];
NSURLRequest *request = [NSURLRequest requestWithURL:#"http://www.google.com.ua"];
[webView loadRequest:request];
}
