Fetching Tweets with Swift IOS - ios

Question

I'm practicing on a sample application that has a social feed page. I'm trying to display each tweet with the corresponding media. I was able to get the text and media but not as one tweet and the further I could get is displaying the media link. Any help on how to get the tweet with the media displayed would be appreciated. To make it clearer the user should be able to view the text and any picture/video from the application without the need to open any links.

#SYou can use TwitterKit SDK in iOS for your App. Twitter SDK is is fully capable to fulfil your needs. Whatever feed functionality you want you just need to configure it in twitter kit.
When showing Tweets you can implement these features for your feed :
The style (dark or light)
Colors (text, links, background)
Action Buttons
The delegate (TWTRTweetViewDelegate) to be notified of user interaction with the Tweet
To Show tweets you can do this :
For showing tweets you have two options :
You can load any public tweets (Attention : For Showing Public Tweets You need Public Tweet IDs)

import UIKit
import TwitterKit
class PublicTweets : UITableViewController {
// setup a 'container' for Tweets
var tweets: [TWTRTweet] = [] {
didSet {
tableView.reloadData()
}
}
var prototypeCell: TWTRTweetTableViewCell?
let tweetTableCellReuseIdentifier = "TweetCell"
var isLoadingTweets = false
override func viewDidLoad() {
super.viewDidLoad()
if let user = Twitter.sharedInstance().sessionStore.session()?.userID {
Twitter.sharedInstance().sessionStore.logOutUserID(user)
}
self.tableView.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 0, right: 0)
// Create a single prototype cell for height calculations.
self.prototypeCell = TWTRTweetTableViewCell(style: .default, reuseIdentifier: tweetTableCellReuseIdentifier)
// Register the identifier for TWTRTweetTableViewCell.
self.tableView.register(TWTRTweetTableViewCell.self, forCellReuseIdentifier: tweetTableCellReuseIdentifier)
// Setup table data
loadTweets()
}
func loadTweets() {
// Do not trigger another request if one is already in progress.
if self.isLoadingTweets {
return
}
self.isLoadingTweets = true
// set tweetIds to find
let tweetIDs = ["944116014828138496","943585637881352192","943840936135741440"];
// Find the tweets with the tweetIDs
let client = TWTRAPIClient()
client.loadTweets(withIDs: tweetIDs) { (twttrs, error) -> Void in
// If there are tweets do something magical
if ((twttrs) != nil) {
// Loop through tweets and do something
for i in twttrs! {
// Append the Tweet to the Tweets to display in the table view.
self.tweets.append(i as TWTRTweet)
}
} else {
print(error as Any)
}
}
}
}
// MARK
// MARK: UITableViewDataSource UITableViewDelegate
extension PublicTweets {
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// Return the number of Tweets.
return tweets.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// Retrieve the Tweet cell.

// Assign the delegate to control events on Tweets.

// Retrieve the Tweet model from loaded Tweets.

func tweetView(_ tweetView: TWTRTweetView, didTap url: URL) {
}
func tweetView(_ tweetView: TWTRTweetView, didTapVideoWith videoURL: URL) {
}
func tweetView(_ tweetView: TWTRTweetView, didTap image: UIImage, with imageURL: URL) {
}

}
func tweetView(_ tweetView: TWTRTweetView, didTapProfileImageFor user: TWTRUser) {
}
func tweetView(_ tweetView: TWTRTweetView, didChange newState: TWTRVideoPlaybackState) {
}
}
You can also show other users tweets by just having their ScreenName or Twitter UserID
For e.g.
//
// SelfTweets.swift
// TwitterFeedDemo
//
// Created by User on 21/12/17.

import Foundation
import UIKit
import TwitterKit
class SelfTweets: TWTRTimelineViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
if let user = Twitter.sharedInstance().sessionStore.session()?.userID {
let client = TWTRAPIClient()
self.dataSource = TWTRUserTimelineDataSource.init(screenName:"li_ios", userID: user, apiClient: client, maxTweetsPerRequest: 10, includeReplies: true, includeRetweets: false)
}
}
}
