Thanks for the tip!
Seems to me that the else enclosure is not needed since the if has a return in it.
Thanks.
You're certainly right, the
elseisn't required, but it does make the logic a little more explicit (to me). I'm not much of an objective-c developer, so I'm not sure what the expected convention would be.Sorry I have no Idea of Objective-C, but is it possible to verify if the url is in the whitelist? I would like to open all not whitelisted URLs in external Safari
You can add URL schemes "mailto" and "tel" as well. That way , if you have < a href=" mailto:a@b.com" > or < a href="tel:1234" >call me</ a>, they open email client and telephone app respectively.
One issue with this fix is that iframes will also open in external Safari. Here is a solution (works with 1.4.1):
/**
(BOOL)webView:(UIWebView *)theWebView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
NSURL *url = [request URL];
if(navigationType == UIWebViewNavigationTypeLinkClicked && ([[url scheme] isEqualToString:@"http"] || [[url scheme] isEqualToString:@"https"])){
[[UIApplication sharedApplication] openURL:url];
return NO;
}
else {
return [self.viewController webView:theWebView shouldStartLoadWithRequest:request navigationType:navigationType];
}
}
Nice, thanks @Ruddiger!
