Firebase数据库在批准后保存数据 [英] Firebase Database saving data after approvement

问题描述

我正在iOS应用上使用firebase数据库！我写得很快.我正在使用发送"按钮在firebaseDatabase上写入数据(例如textField和label值).有什么方法可以接受或拒绝数据库中的数据?我的意思是，如果用户将某些内容添加到文本字段并按send(将其添加到我的数据库中)，那么我想接受或拒绝它，然后再添加到我的数据库中！

I'm using firebase database on an iOS app! I'm writing in swift. I'm using a 'Send' button to write data (ex. textField and label values) on my firebaseDatabase. Is there any way to accept or decline data on my database? What I mean is if a user add something to textfield and press send (which means adding it to my database), I want to accept or decline it to my database, before adding it there!

我的按钮操作:

@IBAction func saveBtn(_ sender: Any) {

        //Saving item to database
        if commentTextField.text !=  "" && placeLabel.text != "Location"
        {

            let place = placeLabel.text

            let key = dbRef!.child("placeLabel").childByAutoId().key


            dbRef!.child(place!+"/placeLabel").child(key).setValue(place)
            dbRef!.child(place!+"/comment").child(key).setValue(commentTextField.text)
            dbRef!.child(place!+"/rating").child(key).setValue(ratingControl.rating)

            commentTextField.text = ""
            //alert
            createAlert(title: "Thank you!", message: "Review submitted.")
            self.navigationController?.popViewController(animated: true)
        }else{
            //alert
            createAlert(title: "Why don't write a review?", message: "Please write a review.")
        }

    }

启用firebase数据库的脱机功能的另一种方法.它会增强处理能力，而您不需要处理它.这仅需一行代码即可实现.

Another way to enable offline capability of firebase database. It will enhance the processing and you don't need to handle this.This will achieve with one line of code only.
