Answer 1

iOS9.2.1

This fixes my 308 issues

Open as “source code”, the plist file, find LSApplicationQueriesSchemes, then add / modify as needed.

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

Answer 2

Try this code:

  FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init]; login.loginBehavior = FBSDKLoginBehaviorWeb; [login logInWithReadPermissions:@[@"email"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) { if (error) { // Process error } else if (result.isCancelled) { // Handle cancellations } else { if ([result.grantedPermissions containsObject:@"email"]) { NSLog(@"result is:%@",result); [self fetchUserInfo]; [login logOut]; } } }]; 

Answer 3

I think this is due to the new iOS 9 URL handling scheme

You need to add trusted URLs to plist under LSApplicationQueriesSchemes
