ios - Facebook 用户没有权限

Question

已授权该应用但拒绝“自动发布”的用户。我如何帮助他们重新添加权限？我什至从他们的列表中删除了该应用程序并删除了他们的用户。当他们辞职时，它不会重新征求他们的许可吗？

NSString *message = NSLocalizedString(@"FACEBOOK_INVITE_MESSAGE", nil);
NSString *link = ITUNES_URL;
NSString *description = NSLocalizedString(@"FACEBOOK_INVITE_DESCRIPTION", nil);
NSString *picture = @"http://trivi.al/Content/images/icon72.png";
NSMutableDictionary *tParams = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                message,     @"message",
                                link,        @"link",
                                description, @"description",
                                picture,     @"picture", nil];
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:sender.tag inSection:[[sender superview] superview].tag];

NSDictionary *playerDict = [((NSArray*)[self.sortedUsersWithoutApp valueForKey:((NSString*)[self.sortedKeysForUsersWithoutApp objectAtIndex:indexPath.section])]) objectAtIndex:indexPath.row];

[[PFFacebookUtils facebook] requestWithGraphPath:[NSString stringWithFormat:@"%@/feed", [playerDict objectForKey:@"id"]] 
                      andParams:tParams
                    andHttpMethod:@"POST"
                    andDelegate:self];
