FBSDKShareDialog in iOS pre-specify certain page

In Facebook SDK v4 for iOS, I use FBSDKShareDialog to share contents to my Facebook page (which I'm one of the Page Admins).

- (IBAction)shareLink:(id)sender {
    FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
    content.contentURL = [NSURL URLWithString:@"http://www.example.com"];
    [FBSDKShareDialog showFromViewController:self
                                  withContent:content
                                     delegate:nil];
}

It will launch Facebook App and a sharing dialog, which I'm allowed to change where I post the share contents.

Can I change the default sharing target to specific page? The default is "Your Timeline".
