You need some permissions from facebook, most important permission is "publish_actions".

You need page_ID of that facebook page to which you want to post.

Then try this:

NSMutableDictionary *params = [NSMutableDictionary dictionary];
[params setObject:@"Your own message" forKey:@"message"];
[params setObject:@"facebook_page_id_path_string" forKey:@"place"];

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"/me/feed" parameters:params HTTPMethod:@"POST"] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
NSLog(@"result %@",result);
NSLog(@"error %@",error);
if (!error) {
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"Posted!" delegate:self cancelButtonTitle:nil otherButtonTitles:nil];
    [alert show];
     double delayInSeconds = 1.0;
     dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
     dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
        [alert dismissWithClickedButtonIndex:0 animated:YES];
     });
  } else {
      NSString *message = @"There was a problem sharing. Please try again!";
      [[[UIAlertView alloc] initWithTitle:nil message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
  }
}];

Hope this helps.
