facebook integration with objective c

Question

My App was work fine, before few days it become crash and give this error:

Terminating app due to uncaught exception 'InvalidOperationException', reason: 'fbauth2 is missing from your Info.plist under LSApplicationQueriesSchemes and is required for iOS 9.0'

When I check the plist file I found that the fbauth2 is there as it should be:

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fb-messenger-api</string>
    <string>fbauth2</string>
    <string>fbshareextension</string>
    <string>twitter</string>
    <string>twitterauth</string>
</array>

any one have any idea about that?

Regards.

Answer 1

You only need to add into your Info.plist. You have to add 
<string>fb-messenger-api</string> for iOS 9.0

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>fbapi</string>
  <string>fb-messenger-api</string>
  <string>fbauth2</string>
  <string>fbshareextension</string>
</array>

Answer 2

You can try this -

In your info.plist , add a row with the key LSApplicationQueriesSchemes . Make sure it is of array type. For it's only element, add the string fbauth2 .
