The following URL scheme was working on previous version but doesn't work anymore on iOS 9:
comgooglemaps://?q=Google+Japan,+Minato,+Tokyo,+Japan¢er=35.660888,139.73073&zoom=15&views=transit
Did something change on iOS 9 that prevent apps from opening other apps using URL schemes?
In iOS 9, Apple has made a change to the handling of URL schemes. Now you need to add "LSApplicationQueriesSchemes" key in plist and then add URLScheme you want to call.
<key>LSApplicationQueriesSchemes</key>
<array>
<string>comgooglemaps</string>
</array>
