What is Travel-it iOS App

Travel-It is an open source iOS made for Steemit travel bloggers. It shows trending posts from travel category. This app is created to help minnows who used travel niche on Steemit. Using this app users can learn writing tactics from trending travel posts and hot travel posts. Users can also use all useful Steem tools to check various details of their Steemit account. Now users can login on app via steemconnect and also upvote posts. App UI is totally changed and created according to user comfort.

New features added in app

The new feature added in the app are following with commit history :

• changed ui of trending travel posts

in this commit i updated UI of trending posts section because previous UI of this section is not so comfortable to use, post with no image or low quality images was looking so ugly. So i reduced size of posts image box and totally redesign the UI of trending posts section. Some pics of new UI are below :-

• hot posts section ui changed

in this commit i updated UI of hots posts section. Here i keep image box same as last UI but change position of user name, post title, upvotes count, post upvotes value and comment on post image. Some images of hot posts section new UI are below :-

• steemconnect implemented in app
  This commit is a big update to app. In this commit i added login via Steemconnect feature to app. As the app is for steemit users so login via steemconnect is a necessary features for users because without this feature the app is bounding users to just read posts but now users can perform other action like upvote the posts they like, they can see their user profile and other things. Now users don't need to go to desktop to upvote the posts. Some images of the feature are below :-

• How i implemented login via steemconnect in app
  To add login via steemconnect in app, first i created app account on steemconnect. The get login url from there. After getting login url, i add a web view in app to redirect user to steemconnect login page. The code below loads steemconnect login page on webview :-

 func setUpWebView() {
        let configuration = WKWebViewConfiguration()
        let userContentController = WKUserContentController()
        configuration.userContentController = userContentController
        self.showLoadingIndicator()
        webview?.load(URLRequest.init(url: URL.init(string: get_login_url)!))
        webview?.uiDelegate = self;
        webview?.navigationDelegate = self
    }

After this when enter his/her username in steemconnect and proceed to login, i used the following delegate methods of webview and save user info like his/her name and auth token in app. After saving required things from steemconnect callback, i redirect user on app main page where they can see trending posts :-

 func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
        print("RequestUrl ========"+(navigationAction.request.url?.absoluteString)!)
        
        decisionHandler(WKNavigationActionPolicy.allow)
        //        decisionHandler(WKNavigationActionPolicy.cancel)
    }
    
    func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Void) {
        print("ResponseUrl ========"+(navigationResponse.response.url?.absoluteString)!)
        
        
        if (navigationResponse.response.url?.absoluteString.contains("access_token"))! {
            DataManager.sharedInstance.saveUserInfo(fromStr: (navigationResponse.response.url?.absoluteString)!)
            decisionHandler(WKNavigationResponsePolicy.cancel);
            self.navigateUserInsideApp()
        }else{
            
            decisionHandler(WKNavigationResponsePolicy.allow);
        }
    }

• added upvote feature to trending posts
  In this commit i added upvote feature to app for logged in users. Because implementing login via steemconnect is not enough for users because after login they can only read posts, so i added upvote feature to app. Now users don't need to to web to upvote the posts they like on app, they can directly upvote posts from app now. Video of upvote feature is below :-

• How the upvote feature works :-
  To add upvote feature in app, i used steem.js broadcast function. When users click on upvote i get all the necessary data from post data and process it to steem.js broadcast feature like this :-

@objc func upvoteButtonClicked(sender: UIButton) {
        let data = self.allPosts[sender.tag]
        let idx = sender.tag
        let author = data["author"]!
        let permlink = data["permlink"]!
        STClient.vote(voter: DataManager.sharedInstance.getUserName(), author: author as! String, permlink: permlink as! String, weight: 10000, to:nil) { (response, error) in
            if error == nil && idx == sender.tag{
                self.getTredingTravelPosts()
            }
        }
        
    }

this function calls the vote functions which i implemented in a swift class :-

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) {
        //        print("jsonData ==============="+"\(NSDictionary_STExtension.getJSONStringFromDictionary(dictionary: body))")
        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)
        }
    }

• added user name and image with login, logout button in user profile
  In this commit i created user profile page in app, so that users can logout from the app and also see their profile image and username on that page. Users can also log in from the user profile too. I had user name saved locally in app but i need to get user image too to show on user profile, so i used the below steem.js api call to get user image and show on user profile :-

func getUserData(userName: String) {
        self.showLoadingIndicator()
        let url = URL(string: "https://steemit.com/@" + userName + ".json")!
        URLSession.shared.dataTask(with: url, completionHandler: {
            (data, response, error) in
            if(error != nil){
                print("error")
            }else{
                do{
                    var json = try JSONSerialization.jsonObject(with: data!, options: []) as! [String: AnyObject]
                        if let userDetailData = json["user"]!["json_metadata"] as? [String: AnyObject] {
                            DispatchQueue.main.async {
                                self.finalUserData = userDetailData["profile"] as? [String: AnyObject]
                                if let userImageUrl = self.finalUserData!["profile_image"] as? String {
                                    self.userImage.sd_setImage(with: URL(string: userImageUrl), completed: nil)
                                    self.userImage.sd_setImage(with: URL(string: userImageUrl), placeholderImage: UIImage(named: "defaultImage.png"))
                                }
                                else {
                                    self.userImage.image = #imageLiteral(resourceName: "defaultImage")
                                }
                            self.stopLoadingIndicator()
                            }
                        }
                }catch let error as NSError{
                    print(error)
                }
            }
        }).resume()
    }

the logout function delete all user saved data from app and redirect user to login page. The logout function is below :-

@IBAction func logoutLoginButtonClicked(_ sender: Any) {
        if self.logoutButton.title == "Login" {
           self.performSegue(withIdentifier: "loginUser", sender: self)
        }
        else {
            UserDefaults.standard.removeObject(forKey: UserDataSaveConstants.st_access_token_save)
            UserDefaults.standard.removeObject(forKey: UserDataSaveConstants.st_userName_save)
            UserDefaults.standard.removeObject(forKey: UserDataSaveConstants.st_expires_in_save)
            UserDefaults.standard.synchronize()
            let mainVc : MainVC = MainVC.instantiateWithStoryboard(appStoryboard: .SB_Main) as! MainVC
            let tAppdelegate = application.delegate as! AppDelegate
            tAppdelegate.window?.rootViewController = mainVc
        }
    }
