Unable to request permission to upload video to facebook from iOS app

Unable to request permission to upload video to facebook from iOS app

I'm using the social framework in iOS 6 to integrate facebook video
uploading into my app. However, nothing happens when I run the program,
and I instead receive this error:
"An active access token must be used to query information about the
current user.","type":"OAuthException","code":2500}}"
I've looked at similar SO questions, but I've only been able to deduce
that I'm not properly requesting permission to use facebook.
Below is my code, which I implemented from this tutorial. Through NSLogs,
I determined that BOOL granted is set to false.
- (void)uploadToFb {
ACAccountStore *accountStore = [[ACAccountStore alloc] init];
ACAccountType *facebookAccountType = [accountStore
accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
// Specify App ID and permissions
NSDictionary *options = @{
ACFacebookAppIdKey: @"2************",
ACFacebookPermissionsKey:
@[@"publish_stream", @"publish_actions"],
ACFacebookAudienceKey:
ACFacebookAudienceFriends
};
[accountStore requestAccessToAccountsWithType:facebookAccountType
options:options
completion:^(BOOL granted,
NSError *e) {
if (granted)
{
NSArray *accounts = [accountStore
accountsWithAccountType:facebookAccountType];
facebookAccount = [accounts lastObject];
}
else
{
// Handle Failure
}
}];
NSURL *videourl = [NSURL
URLWithString:@"https://graph.facebook.com/me/videos"];
NSString *filePath = [outputURL path];
NSURL *pathURL = outputURL;
NSData *videoData = [NSData dataWithContentsOfFile:filePath];
NSDictionary *params = @{
@"title": @"Face Puppets Video",
@"description": @"A funny video I made with the #FacePuppets iOS app."
};
SLRequest *uploadRequest = [SLRequest
requestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodPOST
URL:videourl
parameters:params];
[uploadRequest addMultipartData:videoData
withName:@"source"
type:@"video/quicktime"
filename:[pathURL absoluteString]];
uploadRequest.account = facebookAccount;
[uploadRequest performRequestWithHandler:^(NSData *responseData,
NSHTTPURLResponse *urlResponse, NSError *error) {
NSString *responseString = [[NSString alloc]
initWithData:responseData encoding:NSUTF8StringEncoding];
if(error){
NSLog(@"Error %@", error.localizedDescription);
}else
NSLog(@"%@", responseString);
}];
}
Also, I doubt that I properly added the app id in the plist, could this
also be a problem?
