Obtenga Facebook uid de ACAccountStore en iOS?

Question

Hola, quiero obtener el UID del usuario de Facebook de ACAccountStore en 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.facebookLa cuenta tiene UID, pero no puedo obtenerla ...

Debe llamar a la API Graph de Facebook ; use SLRequest de la siguiente manera:

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
}
});

¡Deberias hacer eso!

Quería obtener el UID sin usar la API de Facebook. Se puede hacer utilizando el siguiente método

 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);
}
}];
