원.밥.영 어플 프로젝트 2차
- Realm Database를 사용하였다.
Realm은 모바일 플랫폼이며 SQLite 및 Core Data를 대신한다.
- DOFavoriteButton 라이브러리를 즐겨찾기 기능에 사용하였다.
- 즐겨찾기 창까지 구현하는 것을 목표로 하였다.
storyboard 수정
이전에 설계한 어플의 뷰에서 TisprCardStack 라이브러리 사용으로 변경된 뷰를 storyboard에 반영하였다.
Model 구현
Sentence.swift
import Foundation
import ObjectMapper
import RealmSwift
import Realm
class Sentence: Object, Mappable {
// primaryKey로 사용할 id
@objc dynamic var id: Int = 0
@objc dynamic var english: String = ""
@objc dynamic var korean: String = ""
// 즐겨찾기 기능을 위한 변수
@objc dynamic var favorite: Bool = false
required convenience init?(map: Map) {
self.init()
}
override static func primaryKey() -> String? {
return "id"
}
func mapping(map: Map) {
english <- map["english"]
korean <- map["korean"]
}
func incrementID() -> Int {
let realm = try! Realm()
return (realm.objects(Sentence.self).max(ofProperty: "id") as Int? ?? 0) + 1
}
// 랜덤 문장 테스트를 위한 랜덤 함수
static func random() -> Sentence? {
let realm = try! Realm()
let sentences = realm.objects(Sentence.self)
if sentences.count == 0 {
return nil
}
let index = Int(arc4random_uniform(UInt32(sentences.count)))
return sentences[index]
}
}
Cell 구현
SentenceCell.swift
class SentenceCell: UITableViewCell {
@IBOutlet var englishLabel: UILabel!
@IBOutlet var koreanLabel: UILabel!
@IBOutlet var favoriteButton: DOFavoriteButton!
var id: Int = 0
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
@IBAction func doFavorite(sender: DOFavoriteButton) {
let realm = try! Realm()
let sentence = realm.objects(Sentence.self).filter("id == \(id)").first
if sender.isSelected {
sender.deselect()
try! realm.write {
sentence?.favorite = false
}
} else {
sender.select()
try! realm.write {
sentence?.favorite = true
}
}
}
}
Controller 구현
SentenceListViewController.swift
class SentenceListViewController: UIViewController {
@IBOutlet var sentenceTableView: UITableView!
@IBOutlet var testButton: UIButton!
var sentences: [Sentence] = []
override func viewDidLoad() {
super.viewDidLoad()
// navigation bar title 지우기
self.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: .plain, target :nil, action: nil)
// realm에 sentences 추가
let realm = try! Realm()
self.sentences = Array(realm.objects(Sentence.self))
}
}
extension SentenceListViewController: UITableViewDelegate, UITableViewDataSource {
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.sentences.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "SentenceCell") as! SentenceCell
cell.id = self.sentences[indexPath.row].id
cell.englishLabel.text = self.sentences[indexPath.row].english
cell.koreanLabel.text = self.sentences[indexPath.row].korean
// 즐겨찾기 버튼 활성화
if self.sentences[indexPath.row].favorite == true {
cell.favoriteButton.select()
} else {
cell.favoriteButton.deselect()
}
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
return
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 60.0
}
func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
return UIView()
}
}
FavoritesViewController.swift
class FavoritesViewController: UIViewController {
@IBOutlet var favoritesSentenceTableView: UITableView!
var sentences: [Sentence] = []
override func viewDidLoad() {
super.viewDidLoad()
let realm = try! Realm()
// favorite 버튼이 누른 것만을 sentences 항목에 추가
self.sentences = Array(realm.objects(Sentence.self).filter("favorite = true"))
}
}
extension FavoritesViewController: UITableViewDelegate, UITableViewDataSource {
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.sentences.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "SentenceCell") as! SentenceCell
cell.englishLabel.text = self.sentences[indexPath.row].english
cell.koreanLabel.text = self.sentences[indexPath.row].korean
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 60.0
}
}
