我想在facebook页面中发布一篇作为管理员的帖子，其中用户是页面的管理员。我有来自
的页面访问令牌[FBRequestConnection startWithGraphPath:@"/me/accounts"
parameters:nil
HTTPMethod:@"GET"
completionHandler:^(
FBRequestConnection *connection,
id result,
NSError *error
) {
NSString *token = [[[result objectForKey:@"data"] objectAtIndex:0] objectForKey:@"access_token"];//accessToken of the page
}];
现在我如何用这个令牌改变FBSession在页面上发布一个帖子作为一个管理员使用graphhapi ?FBDocumentation引用了openFromAccessTokenData。请帮助我，因为我被困在这个很长一段时间。我使用facebook sdk 3.2。提前感谢
