Check if NSURLRequest target is "_blank"?

Question

I'm listening for url loads from my UIWebView. Is there a way to check if the request has a target of "_blank"?:

- (BOOL) webView:(UIWebView *)webView
         shouldStartLoadWithRequest:(NSURLRequest *)request
         navigationType:(UIWebViewNavigationType)navigationType
{
    if ([request targetIs:@"_blank"]) {
        // do something.
    }
}

I don't think its possible to check if an `NSURLRequest` was from an `` link as they are created in response to many things such as Ajax requests, `iframe` loads, etc. However, the effect you are wanting is similar to [this question](http://stackoverflow.com/q/8490038/931452). — Russ, May 22 '15 at 00:34

Don't know about iOS, but as for OS X, it works perfectly, if you use policy delegate. I've placed my answer in this thread, mentioned by Russ above.

Maybe you can use [UIWebView -request] to get the NSURLRequest, and use [NSURLRequest URL] to check if the url contains anything you want.

Yes but a better approach for me would be to catch all urls with target="_blank" instead of having to define my own protocol to do the same. – user1219278 Dec 31 '12 at 04:36
I'm sorry but what do you mean by "defining my own protocol"? – CarmeloS Dec 31 '12 at 04:40
For example, prefixing all my urls with something like "__pattern", or some other token so I know to act on these urls (instead of just relying on target="_blank"). – user1219278 Dec 31 '12 at 04:42
So you mean the request is post by yourself, and you want UIWebView to do something special if the URL conforms to some specific pattern? – CarmeloS Dec 31 '12 at 04:50
Yes I want to launch an instance of mobile safari with the given url if target="_blank". This does not seem to work as it is. – user1219278 Dec 31 '12 at 04:51
Simply put, urls don't have a `target="_blank"` property or aspect about them, its an attribute of an anchor `` HTML element. I honestly wish it was easy to see if the link tapped had this attribute as well – Russ May 22 '15 at 00:42
