I can't speak to your specific problem but if you've setup your webview to have a delegate then use this event and code to trap what a user has clicked on.. and a few more actions as well

//-uiwebview
- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {
	
	//CAPTURE USER LINK-CLICK.
	if (navigationType == UIWebViewNavigationTypeLinkClicked) {
		NSURL *URL = [request URL];	
		if ([[URL scheme] isEqualToString:@"http"]) {
			[[UIApplication sharedApplication] openURL: URL];
		}	 
		return NO;
	}	
	return YES;   
}

links attempting to open new window will not reach this delegate method. this works for "normal" links...

wow that code sample looks like one of my pastebins. Change the scheme to javascript instead of http. scheme is everything before the colon and javascript commands are run with javascript:window.whatever.etc.youget.the.idea

guys, if link has target=_blank, then the delegate method shouldStartLoadWithRequest: does not even reach!

Hi

I made it work using this code:

(void)webViewDidFinishLoad:(UIWebView *)webView
{
	
	[webView stringByEvaluatingJavaScriptFromString:@"{\
					 var a = document.getElementsByTagName(\"a\"); \
					 for (var i=0; i<a.length; i++) \
					 a[i].target = \"_self\";\
					 }"];
	
}

It's a UIWebViewDelegate method implementation. Maybe not a best place, but...

It seems that there's no way to change the reference's targets, except for applying javascript.

Hope that it will help someone.

Just added this to my project and it works like a charm. Hope it helps!

- (void)webViewDidFinishLoad:(UIWebView *)webView
{
	[webView stringByEvaluatingJavaScriptFromString:@"{ var a = document.getElementsByTagName(\"a\");  for (var i=0; i<a.length; i++)  { a[i].target = \"_self\"; }	 }"];
	[webView stringByEvaluatingJavaScriptFromString:@"window.open = function( inurl, blah, blah2 ) {  document.location = inurl; }"];
}

}

Hello;
I'm stuck on the same problem and am trying to get my code to work. I added these two lines of code to this delegate method, but no luck.
Forgive me, but what should I replace "inurl, blah, blah2" with? I don't understand.
Thanks!

Hi,

I am loading an External web page in the UIWebView. When the web page loads, there is an Alert Box ( with OK and Cancel buttons) with some Suggestion/ Info about the web page. I want to block this Alert Box when the web page loads in the UIWebView component in my iphone app. How can I implement in my code?

Thanks in advance.

Kind Regards,
Mahesh

Be careful with this code. It works well on most sites but this will make Gmail and probably other javascript complex websites stop working. I'm working on / looking for a safer solution. Will let you know if and when I find it.

I wrote a blog post on the approach I took when making Rikai Browser for iPad.

The blog post is here: Making target _blank links work in a UIWebView | Long Weekend - iPhone & iPad Apps You'll Love!

Basically similar to some suggestions earlier to use the uiwebview delegate methods.
