It is very simple. That is my implementation of it:
- (void)requestAccessToFacebookAccountWithCompletionHandler:(QCFacebookCommunicatorCompletionHandler)completionHandler {
[[self accountStore] requestAccessToAccountsWithType:[self accountType] options:[self facebookAccountAccessRequestOptionsForReadStreamPermission] completion:^(BOOL accessForReadingGranted, NSError *error) {
if (accessForReadingGranted) {
[[self accountStore] requestAccessToAccountsWithType:[self accountType] options:[self facebookAccountAccessRequestOptionsForPublishStreamPermission] completion:^(BOOL accessForWrittingGranted, NSError *error) {
if (accessForWrittingGranted) {
completionHandler(YES, nil);
} else {
completionHandler(NO, [error userInfo]);
}
}];
} else {
completionHandler(NO, [error userInfo]);
}
}];
}
I just use a helper methods to return dictionaries with options, other stuff is similar to yours.
Then, you can paste your code that is responsible for video uploading instead of the completionHandler calls, or you can use this implementation, and upload video only if the success == YES in completionHandler.
Hope it helps!
