Ios – Resize/fit content ONLY HEIGHT of UIWebView

iosobjective cscrolluiwebview

I'm almost done with resizing my UIWebView. I used the delegate method :

In .h :

@interface myController : UIViewController <UIWebViewDelegate>

In .m :

#pragma mark UIWebView delegate methods

- (void) webViewDidFinishLoad : (UIWebView *) aWebView
{
    CGRect frame = aWebView.frame;
    frame.size.height = 1;
    aWebView.frame = frame;
    CGSize fittingSize = [aWebView sizeThatFits:CGSizeZero];
    frame.size = fittingSize;
    aWebView.frame = frame;
}

But what I need is a webview with fixed-width and variable-height depending on the content.
The previous code is almost fine but the webview is also extended and scrollable horizontally.
I also tried this :

[myWebView setUserInteractionEnabled:NO];

But it only disables the scroll, not adapts the content.

How to fix this please ?

Ios – UIWebView open links in Safari

Add this to the UIWebView delegate:

(edited to check for navigation type. you could also pass through file:// requests which would be relative links)

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    if (navigationType == UIWebViewNavigationTypeLinkClicked ) {
        [[UIApplication sharedApplication] openURL:[request URL]];
        return NO;
    }

    return YES;
}

Swift Version:

func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
        if navigationType == UIWebViewNavigationType.LinkClicked {
            UIApplication.sharedApplication().openURL(request.URL!)
            return false
        }
        return true
    }

Swift 3 version:

func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
    if navigationType == UIWebViewNavigationType.linkClicked {
        UIApplication.shared.openURL(request.url!)
        return false
    }
    return true
}

Swift 4 version:

func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebView.NavigationType) -> Bool {
    guard let url = request.url, navigationType == .linkClicked else { return true }
    UIApplication.shared.open(url, options: [:], completionHandler: nil)
    return false
}

Update

As openURL has been deprecated in iOS 10:

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
        if (navigationType == UIWebViewNavigationTypeLinkClicked ) {
            UIApplication *application = [UIApplication sharedApplication];
            [application openURL:[request URL] options:@{} completionHandler:nil];
            return NO;
        }

        return YES;
}

Iphone – UIWebView resize to fit Content

According to the docs, size to fit:

Resizes and moves the receiver view so it just encloses its subviews.

This does not give you any information about fitting the webView into it's containing view. Is it possible that your webView is trying to display something wider than the screenWidth, and since you have it scroll locked, it is showing the whole width?
