我应该写什么ACFacebookAppIdKey

转到。为iOS创建新应用程序或选择您的应用程序。在仪表板菜单上，您可以看到您的应用程序ID。您应该将此应用程序ID放入AcFaceBookAppID键。

请以良好的格式提问

if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
    ACAccountStore *accountStore = [[ACAccountStore alloc] init];
    ACAccountType *facebookAcc = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
    NSDictionary *options = @{ (NSString *)ACFacebookAppIdKey: @"##########",
                               (NSString *)ACFacebookPermissionsKey: [NSArray arrayWithObject:@"email"],
                               (NSString *)ACFacebookAudienceKey: ACFacebookAudienceEveryone,
                             };
    [accountStore requestAccessToAccountsWithType:facebookAcc options:options completion:^(BOOL granted, NSError *error){
        if (granted) {
            ACAccount *facebookAccount = [[accountStore accountsWithAccountType:facebookAcc] firstObject];
            NSLog(@"facebook usre name: %@, Full name: %@", facebookAccount.username, facebookAccount);

        }
        else if (error)
            NSLog(@"Error occured:%@", [error localizedDescription]);
    }];
