-- `Navigation Controller`가 두개가 구현이 되어있었던 의문을 풀었다. `Navigation Bar`를 이용하기 위함이였다. 쥬스메이커 메인화면에서 재고수정하기 버튼을 터치하게 되면 화면 이동방식은 `modal`이 되어야 한다고 생각했다. 이유는 네비게이션을 따라서 화면을 이동하는 방식이 적절하지 못하다고 생각했기 때문이다. `임시적`으로 화면에 들어가서 재고를 수정하는 용도의 View라는 생각이 들었다. 따라서 메인 화면을 재고수정이 구현되어있는 `ViewController`가 아니라 재고수정 화면에 연결되어있는 `Navigation Controller`에 `Segue`를 연결해서 `modal`을 구현하고, `bar button`을 활용하여 Cancel 버튼을 구현해주었다.

+
+- 재고 수정 화면으로 전환시 재고 관련 Label들이 업데이트 되는 부분을 고민했다. 따로 재고수정 화면에서 재고를 조회하고 Label에 반영해주는 방법도 있겠지만 같은 일을 두번 반복하는 것이 좋지않아 보였고, JuiceMakerViewController의 Label의 값들을 다음 화면에다가 넘겨주면 좋겠다고 생각하여 `prepare`메소드를 이용하여 넘겨주는 방식을 선택했다.
+- Controller 내부 가독성을 어떻게 하면 향상 시킬 수 있는지 고민했다. `extension`을 이용하여 Controller를 분리해보았다. 실제로 가독성도 좋아지는 것 같은 효과[?]를 보았다.
+- 초기에는 Stepper가 터치될 때 (Event가 `Touch Up Inside`일 때) FruitStore의 과일 갯수 저장 프로퍼티 값이 바뀌도록 `IBAction Method` 메소드를 작성해 구현해보았다. 해당 방식으로 구현하면 Stepper의 값이 변화하지 않았을 때에도 `IBAction Method`를 사용하게 되어 메소드 내부에서 수동으로 값의 변화를 체크해야 했다. 자동으로 값의 변화를 체크해주는 방법을 애플에서 제공해주지 않을까 생각이 들었고 Event를 `Touch Up Inside`에서 `Value Changed`로 바꾸어주어 해당 방식을 선택했다.
+- `Label`과 `Button`이 **Dynamic Type** 크기에 따라 커지고 작아질 때마다 실시간으로 반영될 수 있도록 **`adjustsFontForContentSizeCategory`** 옵션을 true로 주었다.
+- `Label`과 `Button`이 **Dynamic Type** 크기에 따라 폰트 크기가 변화할 때마다 글씨가 잘리는 현상을 발견했다. 그래서 버튼 크기 너비에 맞게 크고 작아질 수 있도록 `AdjustsFontSizeToFitWidth` 옵션을 true로 주었다.
+
+## 3-2. 의문점
+
+- 화면 전환 시 Label을 넘겨줄 때 prepare 메소드 내부에서 loadViewIfNeeded 메소드를 이용하여 다음 View를 미리 load 해주고 있다. 이게 적절한 타이밍에 사용했다고 생각하긴 하는데, 정말 적절한건지 모르겠다.
+    - 해당 의문점은 리뷰어인 흰에게 조언을 구했고, View를 불러오기 전에 한번 더 load 하는 것이기 때문에 메모리적인 문제가 발생하여 적절하지 못하다는 리뷰를 받았다.
+- present 메소드를 통해 특정 ViewController를 띄어준 뒤 ViewController의 view 프로퍼티에 접근하여 값을 수정하였을 때 UI가 반영되었다. present 메소드 사용 이전에 ViewController의 UI 관련 값을 설정하고 present를 해주어야하는 줄 알았는데 그렇지 않아 의외였다.
+
+## 3-3. Trouble Shooting
+
+### 1. ViewController 내부 코드 가독성 향상에 대하여
+
+- `상황` Controller의 내부가 길어지고 많아져서 가독성을 향상 시킬 수 있는 방법이 없을까 하다가 extension을 알게되었다.
+
+    ![](https://i.imgur.com/uvbjm9X.png)
+
+
+- `해결` 코드 배치 순서를 활용하여 가독성을 높혀주는 방법도 있겠지만 extension을 이용하여 메서드들을 분리해주었더니 위와 같이 조금은 읽기 수월해진 코드가 되었다.
+
+### 2. prepare() 메소드로 데이터가 제대로 전달이 안되는 경우
+
+- `상황` prepare 메소드를 이용하여 Label의 값들을 넘겨주는 기능을 추가하다가 다음 화면에서 정상적으로 값이 전달되지않아 Label.text 값이 nil인 것을 확인했다. View가 load가 되어있지 않아서 값을 전달하는게 불가능 했다.
+- `시도` 첫번째 방법으로 임시로 값을 담아둘 프로퍼티를 전환할 Controller에 구현해주고 넘겨주려고 했다. 하지만 해당 방법은 프로퍼티를 여러개 생성해야되서 코드 가독성 측면에서 떨어진다고 생각이 들었다.
+- `시도` 두번째 방법으로는 View를 미리 load할 수는 없을까 찾아보다가 `loadViewIfNeeded()` 메소드를 찾게되어 해당 메소드를 호출 후에 Label 값을 전달해주니 정상적으로 다음 화면에서 Label의 값이 적용되었다.
+- `해결` 그러나 위의 방법은 View를 넘어가기전에 한번 더 `load`를 한다는 문제점과 두번째 ViewController의 속성값을 첫번째 ViewController에서 관리한다는 것이 문제가 되었다. 두번째 ViewController의 값들은 **해당 ViewController에서 관리**를 할 수 있도록 전반적으로 코드를 수정해주었고, 화면이 넘어가는 과정에서는 `JuiceMaker`의 **인스턴스**만 넘겨줄 수 있도록 로직을 수정하여 해결하였다.
+
+### 3. button에 Dynamic Type 적용이 안되는 경우
+
+- `상황` 보통 Label은 우측 Inspector에서 간단한 체크로 Automatically Adjusts Font를 설정해줄 수가 있는데 버튼의 titleLabel은 우측 Inspector에서 설정해줄 수가 없었다.
+- `이유와 해결` 찾아보니 코드로 적용하는 방법 뿐이였고, 버튼들 모두 실시간으로 Dynamic Type이 적용될 수 있도록 코드로 옵션을 활성화 해주었다.
+    
+    ```swift
+    // MARK: - Setup Label and Button
+    extension JuiceMakerViewController {
+        func buttonLabelFontSizeFix() {
+            orderStrawberryBananaJuiceButton.titleLabel?.adjustsFontForContentSizeCategory = true
+            orderMangoKiwiJuiceButton.titleLabel?.adjustsFontForContentSizeCategory = true
+            orderStrawberryJuiceButton.titleLabel?.adjustsFontForContentSizeCategory = true
+            orderBananaJuiceButton.titleLabel?.adjustsFontForContentSizeCategory = true
+            orderPineappleJuiceButton.titleLabel?.adjustsFontForContentSizeCategory = true
+            orderKiwiJuiceButton.titleLabel?.adjustsFontForContentSizeCategory = true
+            orderMangoJuiceButton.titleLabel?.adjustsFontForContentSizeCategory = true
+    ```
+    
+- `또 다른 해결 방법` 위와 같이 직접 설정해주어도 되지만 코드 간결화를 주고싶어서 extension을 활용하여 코드를 수정해보았다.
+    ```swift
+    // 개선 후 코드
+    extension UIButton {
+        func setUpTitleLabelFontAttributes() {
+            titleLabel?.adjustsFontForContentSizeCategory = true
+            titleLabel?.adjustsFontSizeToFitWidth = true
+        }
+    }
+    
+    func setUpbuttonLabelFontAttributes() {
+        orderStrawberryBananaJuiceButton.setUpTitleLabelFontAttributes()
+        orderMangoKiwiJuiceButton.setUpTitleLabelFontAttributes()
+        orderStrawberryJuiceButton.setUpTitleLabelFontAttributes()
+        orderBananaJuiceButton.setUpTitleLabelFontAttributes()
+        orderPineappleJuiceButton.setUpTitleLabelFontAttributes()
+        orderKiwiJuiceButton.setUpTitleLabelFontAttributes()
+        orderMangoJuiceButton.setUpTitleLabelFontAttributes()
+    }
+    ```
+    
+### 4. NavigationViewController에 연결되어있는 ViewController를 가져오기
+
+- `상황` NavigationViewController를 생성해서 Label에 접근해서 값을 전달해주려고 했으나 접근할 수가 없었다.
+- `이유` NavigationViewController는 실제로는 뷰가 존재하지 않기 때문에 연결되어있는 ViewController를 가져와야 했다.
+- `해결` topViewController라는 프로퍼티를 이용하여 ViewController를 생성해주고, 타입캐스팅으로 FruitStoreViewController를 가져와서 Label에 접근하는데에 성공했다.
+    ```swift
+    private func presentFruitStoreViewController(_ action: UIAlertAction) {
+            guard let viewController = self.storyboard?.instantiateViewController(withIdentifier: "FruitStoreViewController") as? UINavigationController else { return }
+            self.present(viewController, animated: true, completion: nil)
+            guard let nextViewController = viewController.topViewController as? FruitStoreViewController else { return }
+            setupNextViewLabel(of: nextViewController)
+        }
+    ```
