篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了使用Swift IOS获取推文相关的知识,希望对你有一定的参考价值。
我正在练习具有社交Feed页面的示例应用程序。我正在尝试用相应的媒体显示每条推文。我能够得到文本和媒体,但不是一条推文,我可以得到的更多是显示媒体链接。任何有关如何使用显示的媒体获得推文的帮助将不胜感激。为了更清楚,用户应该能够从应用程序查看文本和任何图片/视频,而无需打开任何链接。
import UIKit
class ViewController: UIViewController,
UITableViewDelegate,UITableViewDataSource {
//importing objects
@IBOutlet weak var mytextfield: UITextField!
@IBOutlet weak var myLabel: UILabel!

var tweets:[String] = []
//Activity Indicator

答案
@SYou可以在ios中使用TwitterKit SDK作为您的应用程序。 Twitter SDK完全能够满足您的需求。无论你想要什么饲料功能,你只需要在twitter工具包中配置它。
显示推文时,您可以为Feed实施以下功能:
样式(深色或浅色)颜色(文本,链接,背景)操作按钮要通知用户与Tweet交互的委托(TWTRTweetViewDelegate)
要显示推文,您可以执行以下操作:
要显示推文,您有两种选择:
- 您可以加载任何公共推文(注意:显示公开推文您需要公共推文ID)

例如
//
// PublicTweets.swift
// TwitterFeedDemo
//
// Created by User on 21/12/17.
// Copyright © 2017 Test Pvt. Ltd. All rights reserved.
//
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.
let cell = tableView.dequeueReusableCell(withIdentifier: tweetTableCellReuseIdentifier, for: indexPath) as! TWTRTweetTableViewCell
// Assign the delegate to control events on Tweets.
cell.tweetView.delegate = self
cell.tweetView.showActionButtons = true
// Retrieve the Tweet model from loaded Tweets.
let tweet = tweets[indexPath.row]
// Configure the cell with the Tweet.
cell.configure(with: tweet)
// Return the Tweet cell.
return cell
}
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
let tweet = self.tweets[indexPath.row]
self.prototypeCell?.configure(with: tweet)
return TWTRTweetTableViewCell.height(for: tweet, style: TWTRTweetViewStyle.compact, width: self.view.bounds.width , showingActions:true)
}
}
extension PublicTweets : TWTRTweetViewDelegate {
//Handle Following Events As Per Your Needs
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, didTap tweet: TWTRTweet) {
}
func tweetView(_ tweetView: TWTRTweetView, didTapProfileImageFor user: TWTRUser) {
}
func tweetView(_ tweetView: TWTRTweetView, didChange newState: TWTRVideoPlaybackState) {
}
}
- 您还可以通过拥有ScreenName或Twitter UserID来显示其他用户的推文
对于例如
//
// SelfTweets.swift
// TwitterFeedDemo
//
// Created by User on 21/12/17.
// Copyright © 2017 Test Pvt. Ltd. All rights reserved.
//
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)
}
}
}
