在iOS Obj-C中何处添加Firebase数据库引用 [英] Where to add Firebase Database Reference in iOS Obj-C

问题描述

我正在通过Firebase设置一个实时数据库，并且混淆了将以下代码行放在哪里：

  self .ref = [[FIRDatabase database] reference]; 
  

以下是我的说明： https://firebase.google.com/docs/database/ios/start

在我的应用程序委托下的（at）接口：

  @property FIRDatabaseReference * ref; 
  

然后，我可以在didFinishLaunchingWithOptions下添加以下内容：

  self.ref = [[FIRDatabase database] reference]; 
  

I'm setting up a realtime database through Firebase and am confused where to put the following line of code:

self.ref = [[FIRDatabase database] reference];

These are the instructions I'm following: https://firebase.google.com/docs/database/ios/start

解决方案

To address this, I added the following line under (at)interface in my App Delegate:

@property FIRDatabaseReference *ref;

Then I could add the following under didFinishLaunchingWithOptions:

self.ref = [[FIRDatabase database] reference];
