map - Scan url scheme ios -


correct me if question duplicate. tried couldn't find answer.

basically, want implement same feature applications aroundme , nearme have: when users found location, can click "navigate here" , app can tell show them navigation applications have on phone , can pick favourite 1 go forward.

i know have api check if url scheme available:

- (bool)canopenurl:(nsurl *)url

but how scan list navigation apps can call , format of each?

do need information available in app database beforehand?

if yes, should url format of each app?

thanks much

this information export/sharing/document controller. not presented list yourself, api show menu in popover or action sheet. means can't manipulate list, tell go open in something.
