Facebook Integration Error ( Accounts.framework) in iOS6 - ios

Question

I am using the following code (showed on WWDC 2012 videos):
self.accountStore = [[ACAccountStore alloc] init];
ACAccountType *facebookAccountType = [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
[self.accountStore requestAccessToAccountsWithType:facebookAccountType
withCompletionHandler:^(BOOL granted, NSError *e) {
if (granted)
{
NSArray *accounts = [self.accountStore
accountsWithAccountType:facebookAccountType];
self.facebookAccount = [accounts lastObject];
} else {
// Fail gracefully...
}
}];
I have also added the NSDictionary to my .plist file:
So, my problem is that I am receiving the following exception:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Access options are required for this account type.'
I have tried with this ACAccountTypeIdentifierTwitter and ACAccountTypeIdentifierSinaWeibo. I am not receiving any exception although they are always returning granted == NO

Answer 1

Well, the WWDC 2012 shows one thing, but the documentation shows another... The method they are using is now deprecated:
– requestAccessToAccountsWithType:withCompletionHandler: Deprecated in iOS 6.0
What you should do:
ACAccountType *facebookAccountType = [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
NSDictionary *options = #{
#"ACFacebookAppIdKey" : #"123456789",
#"ACFacebookPermissionsKey" : #[#"publish_stream"],
#"ACFacebookAudienceKey" : ACFacebookAudienceEveryone}; // Needed only when write permissions are requested
[self.accountStore requestAccessToAccountsWithType:facebookAccountType options:options
completion:^(BOOL granted, NSError *error) {
if (granted)
{
NSArray *accounts = [self.accountStore
accountsWithAccountType:facebookAccountType];
self.facebookAccount = [accounts lastObject];
} else {
NSLog(#"%#",error);
// Fail gracefully...
}
}];

Swift 3
let account = ACAccountStore()
let accountType = account.accountType(withAccountTypeIdentifier: ACAccountTypeIdentifierFacebook)
let options: [AnyHashable : Any] = [ACFacebookAppIdKey: "Your App ID on FB", ACFacebookPermissionsKey: ["publish_stream", "publish_actions"], ACFacebookAudienceKey: ACFacebookAudienceEveryone]
account.requestAccessToAccounts(with: accountType, options: options) { (success, error) in
if success {
if let accounts = account.accounts(with: accountType) {
if accounts.isEmpty {
print("No facebook account found, please add your facebook account in phone settings")
} else {
let facebookAccount = accounts.first as! ACAccount
let message = ["status": "My first Facebook posting "]
let requestURL = URL(string: "https://graph.facebook.com/me/feed")
let postRequest = SLRequest(forServiceType: SLServiceTypeFacebook,
requestMethod: SLRequestMethod.POST,
url: requestURL,
parameters: message)
postRequest?.account = facebookAccount
postRequest?.perform(handler: {(_, urlResponse,
error) in
if let err = error {
print("Error : \(err.localizedDescription)")
}
print("Facebook HTTP response \(String(describing: urlResponse?.statusCode))")
})
}
}
} else {
print("Facebook account error: \(String(describing: error))")
}
}
