shouldStartLoadWithRequest appending link with applewebdata - iphone

Question

I am receiving a description text in HTML format, and I am loading it in a webview, if a link clicked in the description so I load it in separate view controller. But shouldStartLoadWithRequest giving a some appended link. here is my code
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if(navigationType == UIWebViewNavigationTypeLinkClicked) {
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
WebsiteViewController *vc = [storyboard instantiateViewControllerWithIdentifier:#"WebsiteViewController"];
vc.url = request.URL.absoluteString;
NSLog(#"link is : %#", [[request URL] absoluteString]);
[self.navigationController pushViewController:vc animated:YES];
return false;
}
return true;
}
it prints this
link is : applewebdata://038EEEBF-A4C9-4C7D-8FB5-32056714B855/www.yahoo.com
and I am loading it like this
[webViewDescription loadHTMLString:description baseURL:nil];

Answer 1

As you are using loadHTMLString and you are setting baseURL to nil therefore applewebdata URI scheme is used by iOS instead of the “http” in URIs used for accessing internal resources on the device. You could try setting the baseURL

Answer 2

I had a similar issue. In practice, setting the baseURL to 'http://' or something like that wasn't working for me either. I also only saw the applewebdata scheme about 50% of the time, the other 50% of the time I saw the correct scheme I was expecting.
To resolve this, I ended up intercepting -webView:shouldStartLoadWithRequest:navigationType: callbacks and using a regular expression to strip out Apple's applewebdata scheme. Here's what it ended up looking like
// Scheme used to intercept UIWebView callbacks
static NSString *bridgeScheme = #"myCoolScheme";
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
BOOL shouldStartLoad = YES;
NSURL *requestURL = request.URL;
// Strip out applewebdata://<UUID> prefix applied when HTML is loaded locally
if ([requestURL.scheme isEqualToString:#"applewebdata"]) {
NSString *requestURLString = requestURL.absoluteString;
NSString *trimmedRequestURLString = [requestURLString stringByReplacingOccurrencesOfString:#"^(?:applewebdata://[0-9A-Z-]*/?)" withString:#"" options:NSRegularExpressionSearch range:NSMakeRange(0, requestURLString.length)];
if (trimmedRequestURLString.length > 0) {
requestURL = [NSURL URLWithString:trimmedRequestURLString];
}
}
if ([requestURL.scheme isEqualToString:bridgeScheme]) {
// Do your thing
shouldStartLoad = NO;
}
return shouldStartLoad;
}
