iOS 6 - Facebook sharing procedure fails with error “The proxied app is not already installed”

Question

Though, there is such a question Facebook Error (7) iOS 6 it\'s already closed without any answer! While obtaining an access to user\'s facebook account I\'ve got an error:

Answer 1

I've solved this problem! It was because I do not pass permissions array! Though the ACAccountStore class states that this parameter is optional, it is not!

More over the application could launch and ask for basic permissions(as it is implied)!

So, you must always pass a permissions array.

Here's also a description of error codes returned by account store:

typedef enum ACErrorCode {
   ACErrorUnknown = 1,
   ACErrorAccountMissingRequiredProperty,
   ACErrorAccountAuthenticationFailed,
   ACErrorAccountTypeInvalid,
   ACErrorAccountAlreadyExists,
   ACErrorAccountNotFound,
   ACErrorPermissionDenied,
   ACErrorAccessInfoInvalid
} ACErrorCode;

(I've got ACErrorPermissionDenied here)
