home.ts
import { Component, ViewChild } from “@angular/core”;
import { NavController, App, AlertController } from “ionic-angular”;
import { AuthService } from “…/…/providers/auth-service”;
import { Common } from “…/…/providers/common”;
import { Camera, CameraOptions } from “@ionic-native/camera”;
@Component({ selector: “page-home”, templateUrl: “home.html” })
export class HomePage {
@ViewChild(“updatebox”) updatebox;

public photos: any;
public base64Image: string;
public fileImage: string;
public userDetails: any;
public resposeData: any;
public dataSet: any;
public noRecords: boolean;
userPostData = {
    uid: "",
    token: "",
    created: "",
    message: ""
};

constructor(
    public common: Common,
    private alertCtrl: AlertController,
    private camera: Camera,
    public navCtrl: NavController,
    public app: App,
    public authService: AuthService
) {
    const data = JSON.parse(localStorage.getItem("userData"));
    this.userDetails = data.userData;
    this.userPostData.uid = this.userDetails.uid;
    this.userPostData.token = this.userDetails.token;
    this.userPostData.created = "";
    this.noRecords = false
    this.getFeed();
}

ngOnInit() {
    this.dataSet = [];
}

getFeed() {
    this.common.presentLoading();
    this.authService.postData(this.userPostData, "userNewsFeed").then(
        result => {
            this.resposeData = result;
            if (this.resposeData.friendsNewsFeed) {
                this.common.closeLoading();
                this.dataSet = this.resposeData.friendsNewsFeed;
                console.log(this.dataSet);
               
            } else {
                console.log("No access");
            }
        },
        err => {
            //Connection failed message
            console.log("Nac");
        }
    );
}



converTime(time) {
    let a = new Date(time * 1000);
    return a;
}

backToWelcome() {
    const root = this.app.getRootNav();
    root.popToRoot();
}



logout() {
    //Api Token Logout

    localStorage.clear();
    setTimeout(() => this.backToWelcome(), 1000);
}
