在iPhone而非iMac模拟器上运行时，是什么导致连续不断的Firebase命中？

如何解决在iPhone而非iMac模拟器上运行时，是什么导致连续不断的Firebase命中？

在iPhone的Mac模拟器上，它可以正常工作。在实际的iPhone上，即使您将该页面留在应用程序上，页面中的一个页面也会持续访问数据库。然后，这使应用程序不堪重负。如果您在控制台中查看它，则它是来自Firebase请求的连续运行数据流。其根本原因是，在iPhone上运行时会发生这种情况，而在Mac上的iPhone模拟器中运行时不会发生这种情况。 我知道很难理解零碎的代码，但是粘贴所有内容太长了。以下是导致问题的相关快照代码。是的，我知道有嵌套的快照，但是就像我在模拟器上提到的那样，它运行完美。

**let thisUsersUid = Auth.auth().currentUser?.uid //Mr. Dunn's uid

refArtists = Database.database().reference().child("people");

refArtists.observe(DataEventType.value,{snapshot in

…………
    
    self.refArtists.observeSingleEvent(of:.value,with: {snapshot in
        
        let myDomain = snapshot.value as? String
        self.bSnap = myDomain
        print("haaal",self.bSnap)

 ……….

        thisPersonRef.observeSingleEvent(of:.value,with: {snapshot in
        
        if snapshot.exists() {

        query.observeSingleEvent(of: .value,with: { snapshot in
        var allUsers = snapshot.children.allObjects as! [DataSnapshot]
        ///////end (1) of comment
        if let index = allUsers.firstIndex(where: { $0.key == myUid } ) {
        allUsers.remove(at: index) //remove the current user

        for userSnap in allUsers {
        let name = userSnap.childSnapshot(forPath: "postID").value as? String
        print(name,"NNN")

        self.people.removeAll()
        
        for people in snapshot.children.allObjects as! [DataSnapshot] {
        
        
        if people.key != thisUsersUid {
        …….
        
        
        return Calendar.current.isDateInToday(date1)
        }
        
        print(filteredResults,"ppp")
        let countb = filteredResults.compactMap({$0}).count
        print(countb,"bbb")

        self.people.append(peopl)
        

        } else {

        }

        }
        }

        })
        
        } else {
