LongPressureGesture不会抓取第一个单元格

Question

因此，我正在尝试为用户创建一种阻止其他用户或报告其他用户的方法。 我将LongPressGesture添加到了tableView单元格中，但是由于某些原因，它仅适用于indexPath 1及更高版本。它不会获取索引，甚至不会识别第一个单元格。有什么建议吗？

这是我的cellForRowAt

 override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "postCell", for: indexPath) as! PostTableViewCell
    let userID = posts[indexPath.row].userid
    let userDBRef = Database.database().reference().child("users/\(userID)")
    userDBRef.observe(DataEventType.value) { (snapshot) in
        let user = Users(snapshot: snapshot)
        cell.usernameLabel.setTitle(user.username, for: .normal)
        cell.userProfilePic.sd_setImage(with: URL(string: user.photoURL!), placeholderImage: UIImage(named: "1"))
    }




    let lpgr = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress(gestureReconizer:)))
    lpgr.minimumPressDuration = 0.5
    lpgr.delaysTouchesBegan = true
    lpgr.delegate = self
    cell.addGestureRecognizer(lpgr)
    if self.blockedUsersArray.contains("\(posts[indexPath.row].userid)") {
        print("blocked user found")
        self.posts.remove(at: indexPath.row)
        self.tableView.reloadData()
    } else {
        print("no blocked users")
    }

    cell.postDescriptionLabel.text = posts[indexPath.row].description
    cell.postTitleLabel.text = posts[indexPath.row].title
    cell.postTitleLabel.amx_autoScaleFont(forReferenceScreenSize: .size3p5Inch)
    cell.postTitleLabel.amx_autoScaleFont(forReferenceScreenSize: .size4Inch)
    cell.postTitleLabel.amx_autoScaleFont(forReferenceScreenSize: .size4p7Inch)
    cell.postTitleLabel.amx_autoScaleFont(forReferenceScreenSize: .size5p5Inch)
    let image = posts[indexPath.row]
    cell.postImageView.sd_setImage(with: URL(string: image.postImageStringUrl), placeholderImage: UIImage(named: "1"))

    cell.delegate = self


    return cell


}

这是我的handleLongPress（）

@objc func handleLongPress(gestureReconizer: UILongPressGestureRecognizer) {
    if gestureReconizer.state != UIGestureRecognizerState.began { }
    let p = gestureReconizer.location(in: tableView)
    let indexPath = tableView.indexPathForRow(at: p)
    if Auth.auth().currentUser != nil {
        if let index = indexPath {
            var cell = tableView.cellForRow(at: index)
            let userID = posts[(indexPath?.row)!].userid
            let blockedUser = posts[(indexPath?.row)!].username
            self.userToBlock = userID
            print(userID)
            self.userNameToBlock = blockedUser
            let myUserID = Auth.auth().currentUser!.uid

            let alercontroller = UIAlertController(title: "", message: "Please choose one of the following", preferredStyle: .alert)
            let blockAction = UIAlertAction(title: "Block User", style: .destructive) { (action) in
                print("Block" + self.userToBlock!)
                self.profileDBRef?.child("users/" + self.userToBlock! ).child("BlockedUsers").child(myUserID).child(myUserID).setValue(Auth.auth().currentUser?.displayName!)
                self.profileDBRef?.child("users/" + myUserID).child("BlockedUsers").child(userID).child(userID).setValue(self.userNameToBlock)
                self.loadBlockedUser()
                self.tableView.reloadData()

            }
            print(blockedUsersArray)
            let cancel = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
            alercontroller.addAction(blockAction)
            alercontroller.addAction(cancel)
            self.present(alercontroller, animated: true, completion: nil)
            // do stuff with your cell, for example print the indexPath
            print(index.row)
        } else {
            print("Could not find index path")
        }
    } else {
        let alertcontroller = UIAlertController(title: "Please log in", message: "Must Be a user to report or block a user", preferredStyle: .alert)
        let cancel = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
        alertcontroller.addAction(cancel)
        self.present(alertcontroller, animated: true, completion: nil)
    }
