FaceBook共享图像集用户编辑禁用

Question

我在Facebook上分享图片的应用。工作正常，但我想禁用用户interface与post。所以用户不能修改我的initialText这可能吗？

if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
                SLComposeViewController *fbComposer = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

                [fbComposer setInitialText:@"Yes U Are?"];

                if ([fbComposer addImage:[UIImage imageWithData:[Array objectAtIndex:i]]]) {
                }
                [self presentViewController:fbComposer animated:YES completion:nil];

            }else {
                UIAlertView *alertView = [[UIAlertView alloc]
                                          initWithTitle:@"Facebook Error"
                                          message:@"You may not have set up facebook service on your device or\n                                  You may not connected to internent.\nPlease check ..."
                                          delegate:self
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles: nil];
                [alertView show];
            }
        }

听到的是Facebook分享的形象我想只点击帖子btn和Cancle btn。所以用户只能发帖。
