title: Test if any app can handle a url scheme in mobile safari on iOS
body: <p>Is there any way to test if an iOS can handle a custom URL scheme? I have an app that registered a custom url scheme to be able to open the app from a hyperlink in mobile safari. How ever, I'd like to tell the user they need to go to the appstore to download the app if they dont have it installed.</p>
  
  <p>Is there a clever way to test a URL and catch when it fails and the reason for it to fail?</p>
