如何从firebase中的数组中删除字符串值-Howtoremovestringvaluefromarrayinfirebase

I am having a problem removing a kid string from an array of other aid strings in firebase. When a user creates a group chat, they include sharers. Those sharers are added to an array of strings and then added to firebase when made. Now when a user clicks the leave group chat button, I can't figure out a way to remove the current user's user id from that array, in which I have already checked if their uid is in the array. I have tried everything I can guys, first I tried ref.child("Group Chats").child(groupKey).child("sharers").child(myriad).removeValue, and that did not work, I also tried creating a new array without the current users id, removing the old array and adding the new one to firebase, all did not work, now I turn to some fellow coders. How can I remove the current users did from an array of uids in firebase.

我在从firebase中的其他辅助字符串数组中删除一个kid字符串时遇到问题。当用户创建群聊时，他们包括共享者。这些共享者被添加到一个字符串数组中，然后在制作时添加到firebase。现在，当用户单击离开组聊天按钮时，我无法找到从该阵列中删除当前用户的用户ID的方法，其中我已经检查过他们的uid是否在数组中。我已经尝试了所有我能做的事情，首先我尝试了ref.child（“Group Chats”）。child（groupKey）.child（“sharers”）。child（myriad）.removeValue，并且没有用，我也试过创建一个没有当前用户ID的新数组，删除旧数组并将新数组添加到firebase，一切都不起作用，现在我转向一些同伴编写。如何从firebase中的一系列uid中删除当前用户所做的操作。

        let action = UIAlertAction(title: "Leave Group Chat", style: .default, handler: {( alert : UIAlertAction) -> Void in
                let ref = FIRDatabase.database().reference()
                    if let keyp = self.groupChats[indexPath.row].key {

                        ref.child("Group Chats").child(keyp).child("sharers").child(uip).removeValue()



                                              }
                    self.groupChat.removeAll()
                    self.pull()
                    self.pullFromSharers()
                    self.tableViewManage.reloadData()

                })

Thank you!

谢谢！

 ref.child("Group Chats").child(keyp).child("sharers").observe(.value, with: { snapshot in 
    if let sharers = snapshot.value as? [String] { 
    for i in 0..

var url = "your db path is here"
var dataObj = {'sharers':''};
   ref(url).set(dataObj).then(function(res) {
      console.log("response:- ",res);
   });
