Facebook iOS SDK: How to handle SKIP button when requesting publish
I have a code to login to Facebook with 'publish_actions' permission. Here's the snippet:
NSArray *facebookPermissions = [NSArray arrayWithObjects:@"publish_actions", nil];
[FBSession openActiveSessionWithPublishPermissions:[self facebookPermissions]
defaultAudience:FBSessionDefaultAudienceFriends
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
NSLog(@">>> Permissions available: %@", FBSession.activeSession.permissions);
}];
When that method is executed, user will be redirected to Mobile Safari Facebook page and asked whether facebook is allowed to access his/her account.
Screen1:
APPNAME would like to access your public profile and friend list.
[CANCEL] [OK]
After pressing OK, since we use the openActiveSessionWithPublishPermissions method, a second page will appear asking if facebook is allowed to publish stuff on your behalf.
Screen 2:
APPNAME would like to post to your friends on your behalf.
[AUDIENCE] [SKIP] [OK]
The tricky part is, when user clicks SKIP button, the log in the callback still list 'publish_actions' as one of the available permissions. Which is incorrect. The error is also nil. How do I detect this properly?
This is the log:
2013-07-06 16:35:59.037 FbSandbox[56213:c07] >>> Permissions available: ("publish_actions")
Thanks in advance!
You can validate the accepted permissions by calling me/permissions . This will list the permissions the user has allowed. Cross-reference this list with the permissions you ask for and you'll be able to find out which were accepted and which were skipped.
