Why do "_blank" links open inside my app, and the others open inside the webview?

I have an basic test application. It contains a UIWebView.

The website contains links with target="_blank" and some without it. The problem is that what happens is the opposite, the "_blank" open inside the app, and the others open in Safari.

My View controller contains this:

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    if (navigationType == UIWebViewNavigationTypeLinkClicked) {
        [[UIApplication sharedApplication] openURL:request.URL];
        return false;
    }
    return true;
}

How could it be? thanks

You've implemented this behavior yourself. When you receive UIWebViewNavigationTypeLinkClicked, it means that ANY link is clicked, not only links with target="_blank". For this case you invoke -[UIApplication openURL:], so, you open any links in Safari.

When target is "_blank", you will receive the same delegate method with UIWebViewNavigationTypeOther. For this case, you return true, so link is opened in web view. Problem here, that there is no easy way to differ this case from many "other" cases. UIWebView API is far from perfect. I suggest to switch to WKWebView.

See this question Open target="_blank" links outside of UIWebView in Safari for details about UIWebView-based implementation of this functionality.

UPD: Checked again. For case with target="_blank", I receive 2 subsequent shouldStartLoadWithRequest: calls, first with UIWebViewNavigationTypeLinkClicked, second with UIWebViewNavigationTypeOther. So, in my case all links opened in Safari with code from question. Checked on iOS 9.1 and iOS 8.4.
