Change FBSession with page access token to publish post on fb page as admin - facebook-graph-api

Question

I want to publish a post as admin in a facebook page where the user is admin of the page.
I have the page access token from
[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
}];
Now how can i change the FBSession with this token to publish a post on the page as an admin using GraphAPI? FBDocumentation refers to this for openFromAccessTokenData . Please help as i m stuck with this for long time. I m using facebook sdk 3.2. Thanks in advance
