What is Mobile Safari's custom URL Scheme?
ios, mobile-safari, url-scheme
Solution
There is no Safari URL scheme. If you make one up and use it in your html you can check for it though.
Implement the `UIWebViewDelegate` method `webView:shouldStartLoadWithRequest:navigationType:`. Return 'NO' for the requests that you want to shunt to mobile safari. Call `UIApplication` `openURL` with the request's URL.
Something like this:
- (BOOL) webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
// all clicked links!
if ( navigationType == UIWebViewNavigationTypeLinkClicked )
{
[[UIApplication sharedApplication] openURL: request.URL];
return NO;
}
// or, custom URL scheme!
if ( [request.URL.scheme isEqualToString: @"my-open-in-safari"] )
{
// remap back to http. untested!
NSURL* url = [NSURL URLWithString: [request.URL.absoluteString stringByReplacingOccurrencesOfString: @"my-open-in-safari" withString: @"http" ]];
[[UIApplication sharedApplication] openURL: url];
return NO;
}
return YES;
}
Problem
iOS URL Schemes allow web sites to launch apps like so: - `twitter://timeline` launches Twitter - `googlechrome://google.com` launches Chrome - `fb://root` launches Facebook - `______________` launches Safari? (not `http://`, since Safari won't launch from `UIWebView`) What custom url scheme triggers Safari to launch (even from within another app's `UIWebView`)? To clarify, I'm not looking for `[[UIApplication sharedApplication] openURL: request.URL];` Instead I'm looking for how a website can allow a user to launch Mobile Safari from within the `UIWebView` of another app (Google Chrome, Twitter, etc.). Example HTML links that pop open other apps: ``` <a href="twitter://timeline">Open Twitter</a> <a href="googlechrome://google.com">Open site in Chrome</a> <a href="fb://root">Open Facebook</a> ``` I'm looking for something similar to these non-working examples: ``` <a href="safari://google.com">Open Safari [Doesn't work]</a> <a href="webkit://google.com">Open Webkit [Doesn't work]</a> ``` Here's a jsFiddle of the same: http://jsfiddle.net/gXLjF/9/embedded/result/ Try opening this URL in iOS Google Chrome and opening Safari with the links.
