Using SLRequest in iOS 6 with Facebook

问题

I'm currently trying to use an SLRequest to post a status on to facebook this is the code i have:

ACAccountStore *accountStore = [[ACAccountStore alloc] init];
    ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
    NSLog(@"0");
    [accountStore requestAccessToAccountsWithType:accountType options:@{ACFacebookAppIdKey : @"00000000000", ACFacebookPermissionsKey : @"publish_stream", ACFacebookAudienceKey : ACFacebookAudienceFriends} completion:^(BOOL granted, NSError *error) {
        if(granted) {
            NSLog(@"1");
            NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];
            NSLog(@"2");
            if ([accountsArray count] > 0) {
                NSLog(@"3");
                ACAccount *facebookAccount = [accountsArray objectAtIndex:0];
                NSLog(@"4");
                SLRequest *facebookRequest = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                                                requestMethod:SLRequestMethodPOST
                                                                          URL:[NSURL URLWithString:@"https://graph.facebook.com/me/feed"]
                                                                   parameters:[NSDictionary dictionaryWithObject:post forKey:@"message"]];
                NSLog(@"5");

                [facebookRequest setAccount:facebookAccount];
                NSLog(@"6");

                [facebookRequest performRequestWithHandler:^(NSData* responseData, NSHTTPURLResponse* urlResponse, NSError* error) {
                    NSLog(@"%@", [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]);
                }];


            }
        }
    }];

however the code i have doesn't want to get past if(granted){ but i can't tell why what I've done isn't working. Any help would be appreciated!

回答1:

In my case, to resolve this, I register the Bundle ID in the properties of my APP on facebook.

Edit your APP on facebook and look for "Select how your app integrates with Facebook" and register the Bundle ID of your project on "iOS Bundle ID" in "Native iOS App".

If not your case, try to read the error message:

if(granted) {
    ...
}
else {
    NSLog([NSString stringWithFormat:@"%@", error.localizedDescription]);
}

if error.code == 6, then this is the error message that will appear if the user has not signed into Facebook from Settings app.
