Scroll a UIWebView

The example below, is placed in your viewDidLoad function.� In the case below, I have created the objects without the use of the Interface Builder.

The first thing we need to do is create a CGRect the size of our view:

CGRect bounds = [ [ UIScreen mainScreen ] applicationFrame ];

The next thing to do is to create our UIScrollView:

UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:bounds];

We've initialized our scrollview the size of our entire view.� Now, we need to create our webview:

UIWebView *webView = [ [ UIWebView alloc ] initWithFrame:[scrollView bounds]];

Our webView has now been initialized with the bounds of our scrollView.� The next thing we do is load our content from our webpage:

NSURLRequest *request = [ NSURLRequest requestWithURL:url ];

�[ webView loadRequest: request ];

The following code assumes we've created an NSUrl called url with the website we want to load.� Once we've loaded our webpage, we need to tell our scrollview the size of our content.� In this case, we set it to the size of our webview that we've loaded:

scrollView.contentSize = [webView bounds].size;

Next, we need to add our webview to our scrollview:

[scrollView addSubview:webView];

Finally, we need to set our view as the scrollview:

self.view = scrollView;

That's it, now your webview is scrollable!
