我正在尝试为我的应用设置关注/关注者系统。我已经设置了装饰并显示。我的问题是,即使我知道它应该是假的,它也总是显示为真。我尝试了各种 if 语句,但似乎无法使用正确的变量或常量来运行检查,以便数组返回 true 或 false。数组 isFollowing[false] 以这种方式初始化。

self.backendless.persistenceService.of(BackendlessUser.ofClass()).find( query, response: { ( objectId : BackendlessCollection!) -> () in
    let currentPage = objectId.getCurrentPage()

    for objects in currentPage as! [BackendlessUser] {

        if (objects.objectId != self.backendless.userService.currentUser.objectId) {

            self.userids.append(objects.objectId)
            self.backendless.persistenceService.of(objects.ofClass()).find( query, response: { objects -> () in

                    if let objects = objects {
                        self.isFollowing.append(true)
                    } else {
                        self.isFollowing.append(false)
                    }

                    if self.isFollowing.count == self.usernames.count{
                        dispatch_async(dispatch_get_main_queue(), { () -> Void in
                            self.tableView.reloadData()
                        })
                    }
                }, error: { ( fault : Fault!) -> () in
                    print("Server reported an error: \(fault)")
                }
            )
        }
    }
})
