Where to add Firebase Database Reference in iOS Obj-C

Question

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];
         


        

Answer 1

Its simple, Just Add following line in your AppDelegate.h

@property (nonatomic, readonly, strong) FIRDatabaseReference * ref;// Property 

After adding,In your AppDelegate.m didFinishLaunchingWithOption Replace

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

With

_ref = [[FIRDatabase database] reference];  

Problem Solved.. :)
