URL Scheme is Installed in iOS

Question

I am Integrating Google Maps URL Scheme in my Application:

[[UIApplication sharedApplication] canOpenURL:
[NSURL URLWithString:@"comgooglemaps://"]];

I am curios if there is some code to detect if Google Map isn't installed and redirect to App Store URL. Thanks for your Help.

If it return true, that means the Google Map app has been installed.

if (![[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"comgooglemaps://"]])
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://itunes.apple.com/en/app/google-maps/id585027354?mt=8"]];
else
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"comgooglemaps://"]];
