• Get Stemit Trending posts

The new section for the Steemit Users has been added to the app to allow the News Lovers read all Trending, Hot and Promoted News posts in the App itself. The users now gonna love this new section with the UI part has been in the focus with interesting things around.

• Implementation Code

 func getSteemNewsWith(category : String) {
        self.startAnimator()
        APIMaster.getSteemitNewsWith(category: category, completion: { (anyObject, httpResponse) in
            DispatchQueue.main.async(execute: {
                self.stopAnimator()
            })
            DispatchQueue.global(qos: .background).async(execute: {
                self.currentNewsArray.removeAll()
                if let jsonArray = anyObject as? [[String : Any]] {
                    jsonArray.forEach({ (object) in
                        let steemNewsModel = SteemNews.init(info: object)
                        self.currentNewsArray.append(steemNewsModel)
                    })
                } else {
                    var errorMsg = Messages.InternalServerError
                    if let infoArr = (anyObject as? [Any]), let errorInfo = infoArr[1] as? [String : Any], let message =  errorInfo["message"] as? String {
                        errorMsg =  message
                    }
                    DispatchQueue.main.async(execute: {
                        self.showAlertWith(title: "Error", message: errorMsg)
                    })
                }
                DispatchQueue.main.asyncAfter(deadline: .now() + 0.1, execute: {
                    self.tableview.reloadData()
                })
            })
        }) { (error) in
            DispatchQueue.main.async(execute: {
                self.stopAnimator()
                self.showAlertWith(title: "Error", message: error.localizedDescription)
            })
        }
    }

On the first time app loads, it will fetch trending news, On clicking the discussion button the user has three options to choose from trending, hot and promoted ones. On selecting one from the three this method is called

  func getSteemitNewsWith(category : String, completion : APICompletionHandler, failure : APIFailureHandler) {
        let urlStr = "https://api.steemjs.com/\(category)?query=%7B%22tag%22%3A%22news%22%2C%20%22limit%22%3A%20%2210%22%7D"
        let url = URL.init(string: urlStr)
        let request = URLRequest.init(url: url!)
        self.forwardRequest(request: request, httpMethod: HttpMethods.HttpMethod_GET, completion: completion, failure: failure)
    }

In this method we have a request which takes the Url with the category param inside and send the request to make the app load the specific data with response.

• Upvote post
  User has the liability to upvote the post from the app itself which the user likes and wanna support the community by rewarding them. Users now gonna love the feature and like to add this to their favourite one from all of the ones.

• Implementation Code

 func didClickUpvoteBtn(_ sender: UIButton) {
        self.startAnimator()
        let steemNews = self.currentNewsArray[sender.tag]
        let author = steemNews.author
        let permlink = steemNews.permlink
        STClient.vote(voter: DataManager.sharedInstance.getUserName(), author: author, permlink: permlink, weight: 10000, to:nil) { (response, error) in
            DispatchQueue.main.async(execute: {
                self.stopAnimator()
            })
            if error == nil {
                self.currentNewsArray[sender.tag].have_i_voted = true
                DispatchQueue.main.async(execute: {
                    self.tableview.reloadData()
                    self.tableview.scrollToRow(at: IndexPath.init(row: 0, section: sender.tag), at: UITableViewScrollPosition.middle, animated: true)
                })
            }
        }
    }

To upvote a post we need the username of the user posting the upvote, author the post the user posting, permlink of the post. This function call another function 'vote' function which is defined in Client.swift

    class func vote(
        voter:String,
        author:String,
        permlink:String,
        weight:NSInteger,
        to:UIView?,
        finished:@escaping STClientCallBack){
        let param = ["voter": voter,
                     "author": author,
                     "permlink":permlink,
                     "weight":weight,
                     ] as [String : Any]
        self.broadcast(body: ["operations":[["vote",param]]],to:to,finished: finished)
    }

 class func broadcast(body:Dictionary<String, Any>,
                         to:UIView?,
                         finished:@escaping STClientCallBack) {
        self.post(url: post_broadcast, body: body, to:to,finished: finished)
    }
  
   class func post(url:String,body:Dictionary<String, Any>,to:UIView?,finished:@escaping STClientCallBack) -> Void {
        let client = NetworkTools.sharedTools;
         client.requestSerializer.setValue(DataManager.sharedInstance.getToken(), forHTTPHeaderField: "Authorization")
        client.request(method: .POST, urlString: url, parameters: body as AnyObject) { (response, error) in
            finished(response,error)
        }
    }

The vote function takes some parameters for the post to be upvoed. The main param which is 'operations' which is a key and against which an json to post which contains 'vote' as key and posting paramaters. The broadcast function call another function called postwhich gets the actual data for the upvote post.

func request(method: AFRequestMethod = .GET, urlString: String, parameters: AnyObject?, finished:@escaping AFNRequestCallBack){
        
        print("urlString ============  " + urlString)
        print("parameters ============  " + String(describing: parameters))
        
        //success closure
        let success = { (dataTask: URLSessionDataTask, responseObject: Any?) -> Void in
            print("responseObject =========" + "\(String(describing: responseObject))")
            finished(responseObject, nil)
        }
        
        //failure closure
        let failure = { (dataTask: URLSessionDataTask?, error: Error) -> Void in
            print("request Error =========" + error.localizedDescription)
            finished(nil, error)
        }
        
        if method == .GET {
            get(urlString,parameters:parameters,progress:nil,success:success,failure:failure)
        }else{
            post(urlString, parameters: parameters, progress: nil, success:success, failure: failure)
        }
    }

This request method takes the HTTP Method GET, url string of the resource, parameters to post, and a param as closure called finished which runs asynchronous and make a call back on recieving the data back.

Roadmap for future releases

• To add a downvote feature if the user has already upvoted the post.
• to add a comment feature on the post.
• To allow the user to add a post from the app.
• To allow users to see authors profile into the app.
• To allow users to transfer steem powers to other users.
• Allow Non-Steemit users to bypass the login process and show them the pathway to create Steemit account, so that they can now login via Steemit account into the app.

How to run the app

The app is currently not available on app store but still you can install it on your iPhone. For this you need to have following things :-
