When you show web content in a UIWebView, links that open a popup do nothing.

This makes sense. Since UIWebView is an embedded control in your app, there is no logical default for popups.

So how will users view those pages? The solution is to convert all popups to normal links before displaying the web page:

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