Question

Hi i want to get the Facebook user's UID from ACAccountStore in iOS 6
self.accountStore = [[ACAccountStore alloc]init];
ACAccountType *FBaccountType= [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
NSString *key = #"01234567890123";
NSDictionary *dictFB = [NSDictionary dictionaryWithObjectsAndKeys:key,ACFacebookAppIdKey,#[#"email"],ACFacebookPermissionsKey, nil];
[self.accountStore requestAccessToAccountsWithType:FBaccountType options:dictFB completion:
^(BOOL granted, NSError *e) {
if (granted) {
NSArray *accounts = [self.accountStore accountsWithAccountType:FBaccountType];
//it will always be the last object with single sign on
self.facebookAccount = [accounts lastObject];
//i Want to get the Facebook UID and log it here
NSLog(#"facebook account =%#",self.facebookAccount);
} else {
//Fail gracefully...
NSLog(#"error getting permission %#",e);
}
}];
self.facebookAccount has UID, but i am unable to get it...

I wanted to get the UID without using the Facebook API. It can done by using the following method
self.accountStore = [[ACAccountStore alloc]init];
ACAccountType *FBaccountType= [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
NSString *key = #"01234567890123";
NSDictionary *dictFB = [NSDictionary dictionaryWithObjectsAndKeys:key,ACFacebookAppIdKey,#[#"email"],ACFacebookPermissionsKey, nil];
[self.accountStore requestAccessToAccountsWithType:FBaccountType options:dictFB completion:
^(BOOL granted, NSError *e) {
if (granted) {
NSArray *accounts = [self.accountStore accountsWithAccountType:FBaccountType];
//it will always be the last object with single sign on
self.facebookAccount = [accounts lastObject];
//i got the Facebook UID and logged it here (ANSWER)
NSLog(#"facebook account =%#",[self.facebookAccount valueForKeyPath:#"properties.uid"]);
} else {
//Fail gracefully...
NSLog(#"error getting permission %#",e);
}
}];

You need to call the Facebook Graph API; use the SLRequest as follows:
NSUrl requestURL = NSUrl.FromString("https://graph.facebook.com/me");
SLRequest sl = SLRequest.Create(SLServiceKind.Facebook, SLRequestMethod.Get, requestURL, null);
sl.Account = // your ACAccount object here
sl.PerformRequest((data, response, error) => {
if (error == null) {
// success! parse response
}
else {
// handle failure
}
});
That should do it!
