Faster / Easier / Together

2020.06 ~ ing

• INFP
• iAmSomething
• implement : SplashView, SignInView, HomeView, SearchView, OrderView

• ENTP
• hansolnoh95
• Implement : LoginView, SearchView, OrderView, OrderStatusView, MyPageView

• Faster : You don't have to be late on class for long, boring printing process. Go faster and take a look your lecture notes once more!

• Easier : You don't have to consume your energy in front of printing computers and printers anymore! Just upload your files with your mobile phone on the way you go to your school:)

• Together : We know your difficulties of your college life,,, cuz we are students as well. So, why don't we go forward together?!

based on API Design Guidelines. Some key rules are below.

• use 2 spaces for indentation.

• use a whitespace( ) not in front of but only after colon(:).

  • example

    let name: String

• if max length of a line exceeded, line breaking should be after last word is finished.

• if max length of a line exceeded during function calling, line breaking should be based on parameters. cf, if parameters have more than double closures, line must be breaked.

• nothing except last closure can be on same position with first letter of block.

  • example

    guard let pvc = self.storyboard?.instantiateViewController(
    	identifier="secondVC") as? SecondViewController
    	else {return}

• a line should not be over 99 letters.

• there should not be whitespaces in blank lines.
• every last line of files should be a blank line.

• module import should be sorted internal to external(third party), and alphabet.

• do not include needless words.
• use camelCase not snake_case.
• abbreviation should be UPPERCASE except being first letter of a word.
• use name based on roles.

• use UpperCamelCase in a class name.
• no prefix in class name.

• use lowerCamelCase in a function name.

• do not use get, set in function name if possible.

• prefix

  • will : supposed to do an action.
  • did : after a certain action.
  • should : returns a bool value.

• use protocolName in delegate functions.

  • preferred example

  protocol MyCellDelegate {
    func myCellWillPresent(_ cell: MyCell)
    func myCell(_ cell: MyCell, didTapFollowButtonWith user: User)
  }

  • not preferred example

  protocol MyCellDelegate {
    func willPresent(_ cell: MyCell)
    func myCell(_ cell: MyCell, didTapFollowButtonWith user: User)
  }

• use lowerCamelCase in a variable name.

• use lowerCamelCase in a constant name.

• use triple slash(///) for comment

• do not use comment type like C (/* ... */) .

  • preferred example

  /// MARK - IBOutlets
  @IBOutlet weak var tableView: UITableView!
  @IBOutlet weak var nameLabel: UILabel!

  • not preferred example

  /* these are IBOutlets
      that are connected with objects on storyboard */
  @IBOutlet weak var tableView: UITableView!
  @IBOutlet weak var nameLabel: UILabel!

• avoid block comments inline with code.

• use then to initialize properties of variables during declaration.

  • example

  let nameLabel = UILabel().then{
    $0.backgroundColor = .white
    $0.textColor = .blue
    $0.text = "world"
  }

• feat : add new features
• fix : modify some errors or bugs
• docs : modify documents
• style : format code style or nothing is changed

• content should not be over 50 letters and starts with Capital letter.
• do not use past tense but use present tense.
  • preferred example : Fix HomeView
  • not preferred example : Fixed HomeView

Commonly used API and Font related files are managed in this folder

• API: ServerAPI, NaverMapAPI(NMapsMap)
• Fonts: Apple SD Gothic Neo

Commonly used Model and Extension related files are managed in this folder

There are 5 major functions in this project

1. Home
2. Search
3. Order
4. Status
5. MyPage
6. Login and Signin

Groups are devided by function and each groups has sources and resources folders.

These files can included in sources folder

• Viewcontrollers
• Views
• Cells
• APIServices
• Models

These files can included in resources folder

• Storyboards

• Swift 5
• Xcode 11.5
• CocoaPod 1.9.3

• Alamofire 4.8.2 : to communicate with server
• Kingfisher 5.0 : to communicate with server
• NMapsMap : to implement a map view
• SwiftGifOrigin 1.7.0 : to implement a splash

• Launchscreen.storyboard can't use thirdparty classes like Lottie of Airbnb. In order to make custom splash, SplashViewController is implemented using Lottie. Lottie is library of managing animations using .json files of images like you can see above.

• The application start with Splash view controller and present Log-in view after splash animation is ended.

• splash json file can't handle every devices because they have their own screen size. so, It have to be loaded by different file for different UIScreen size. it was important to figure out boundary of view size by swift programmally.

    func getLayoutofUserDevice(){
      if(UIScreen.main.bounds.size.width == 375 && UIScreen.main.bounds.size.height == 667){ // i8
        self.splashJsonName = "splash_i8"
      }
      else if(UIScreen.main.bounds.size.width == 414 && UIScreen.main.bounds.size.height == 896){// 11
        self.splashJsonName = "splash_i11"
        
      }
      else if(UIScreen.main.bounds.size.width == 375 && UIScreen.main.bounds.size.height == 812) { // xs
        self.splashJsonName = "splash_xs"
      }
    }

• After splash animation ended, login view is loaded. in login view, there are two textfield for id / password. Log in button initiate networking with server py POST. With empty textfield, Log in button shows alert and message.
• In sing up view, Name, Id, password and university information is needed to activate Sign up button. Every textfield are checked if it is empty when any textfield ended typing or any buttons are clicked.
• After insert ID textfield, ID check button must be clicked. ID Check button communicate with server by POST action and check if there is a same ID in server. if there is no same ID in server field, small label below textfield will shows that saying it is okay to continue sign up. if there is same ID in server, small label below textfield will notice that there is same ID in server, and textfiled will be cleared.
• After that, In pw field, two textfiled must be filled in same text. Texts are checked when one of two textfiled ended typing. If two text are not same, small label below second textfield will show that pw is incorrect.
• University must selected to locate position of users.
• After all buttons are clicked, and Every textfield are filled properly, Sign up button will activate. with Sign up button, client send user information to server and recieve results.

• After log in, the First view of Tabbar is Home view.

• When Home view is loaded, communication with server is initiate in same time. and get informations that will be showed in Home view.

• There are two values are get from server, user name and current status.

• By status information, Lottie Animation is changed and Label is also changed by status information like below code .

          switch (self.statusIdx ?? 0){
          case 2:
            self.progressLabel?.text = "인쇄 진행 중이에요!"
            self.jsonName = self.deviceInfo + "_2"
          case 3:
            self.progressLabel?.text = "인쇄가 완료되었어요 :)"
            self.jsonName = self.deviceInfo + "_3"
            
          default:
            self.progressLabel?.text = "인쇄를 시작해볼까요?"
            self.jsonName = self.deviceInfo + "_1"
          }

• Alert button in top-right corner persent current alert informations.

• in alert view, every cells have toggle image assets. if user check alert, alert image go inactive.

• display a store list for user in StoreView using UICollectionView. Back button in navigation bar is linked HomeView whitch is first item of tabbar. and map button in right side of the navigation bar presents mapview the cell is disabled when the store is closed. University selection view present university table view and can be changed by selection of tableview. Every cells are touchable and push navigationcontroller of section 3 below. when the favorate button of collectionviewcell is cliked, client send a boolean value to server and refresh the collectionview.
• select college option to change current college information and a store list along to it using UITableView
• display the store details when a store is clicked on the 1st view. favBtn is activated with blue color and post to server that the store is added to a favorite list when the button is clicked. push to the waiting list view of a order function using by UINavigationController when the orderBtn is clicked.
• display the map view when a map button on the 1st view is clicked using Naver Map API with CocoaPod 'NMapsMap'. This view shows stores nearby the selected college using by NMGLatLng on NMapsMap and a marker. markers become bigger and a information window appear over the marker when marker is clicked. dismiss to presenting view by presenting modally and push to storeDetailView using by UINavigationContoroller when the information window is clicked.

• third item of tabbar presents Order view. which find stores to order printing service using UITableView.

• When view loaded, user send token to server and get store list nearby university. 3 sections are divided by favorite store, recently visited store, and all stores nearby. server give users store list and informations and 3 different sections are implemented by different arrays.

• Every cells can be selected. when selection occurs, button appears from bottom and disappear when selection canceled.

• Selection cannot be duplicated. Using _selectedIndexPath, duplicated selection problems are solved.

        if indexPath.compare(_selectedIndexPath!) == ComparisonResult.orderedSame{ /*이미 클릭되어 있는 cell을 클릭*/
          _selectedIndexPath = nil
          clearAllSelections()
          selectionBtnHide()
        }
        else { /*클릭되어 있지 않은 셀을 클릭할 때*/
          selectionBtnAppear()
          switch indexPath.section {
          case 0:
            cell.itemSelected(isSelected: true)
            storeNameInSelection.text = recentStorelist[indexPath.row].store_name
            
          case 1:
            cell.itemSelected(isSelected: true)
            storeNameInSelection.text = favorageStorelist[indexPath.row].store_name
            
          case 2:
            cell.itemSelected(isSelected: true)
            storeNameInSelection.text = defaultStorelist[indexPath.row].store_name
          default:
            cell.itemSelected(isSelected: true)
          }
                  
          switch _selectedIndexPath!.section {
          case 0:
            oldcell.itemSelected(isSelected: false)
          case 1:
            oldcell.itemSelected(isSelected: false)
          case 2:
            oldcell.itemSelected(isSelected: false)
          default:
            oldcell.itemSelected(isSelected: false)
          }
          _selectedIndexPath = indexPath
        }
