In my app i integrated facebook login , and put all the settings required. But when i was trying to login , i get this error
-canOpenURL: failed for URL: "fbauth2:/" - error: "(null)"
But i have put the
<key>LSApplicationQueriesSchemes</key>
<array>
<string>fbapi</string>
<string>fb-messenger-api</string>
<string>fbauth2</string>
<string>fbshareextension</string>
in the .plist file , is there anyway that i can find the issue ??
