Cannot scroll in UIWebView in iOS

Question

I created a webview programmatically and I am unable to enable scrolling in this view.

How do I enable scrolling?

    UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0,40, 325, 1000)];
    webView.contentMode = UIViewContentModeScaleAspectFit;     
    [webView setBackgroundColor:[UIColor clearColor]];
    [webView loadHTMLString:html baseURL:nil];
    [self.view insertSubview:webView atIndex:0];

Thanks In Advance !

Answer 1

To enable scrolling,

webview.scrollView.scrollEnabled = TRUE;

and instead of writing this,

webView.contentMode = UIViewContentModeScaleAspectFit;

write this,

webview.scalesPageToFit = TRUE;

Answer 2

Removing from Interface Builder and adding via code did for me. For some reason in IB it wasn't scrolling.

UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 64, 320, 50)];
[self.view addSubview: webView];

Answer 3

These are the possible solutions.

i) You webview may be large in size than you expected or your content is lesser than the webview size.

2) Implement following method.

func webViewDidFinishLoad(webView: UIWebView)
{
    appDelegate.hideLoadingView()

    let res: NSString = webView.stringByEvaluatingJavaScriptFromString("document.body.offsetHeight;")!
    let h: CGFloat = CGFloat(res.integerValue)
    agreementContentView.scrollView.contentSize = CGSizeMake(webView.frame.size.width, h + 50); // Offset if required
}
