Why?

I wanted an app that allows you to:

• Make choice between random food.
• Find near by restaurants of selected menu.
• Find a recipe for selected menu and make it by yourself.

So that by using this app people will save time from browsing these information separately.

Usage

The primary purpose of this project is to help people choose what to eat for a meal. Many people today have diffuculty choosing what to eat everyday. If you are in this case, open FoodChoose App. This app will show random food images one by one on the screen. If you dont like the food on the screen, simply swipe the finger to left. Then new menu will appear. Keep doing this until you find the menu you want to eat. After you decide the menu, you can either find nearby restranut or find recipes for the menu.

If you choose to make food by your self, click the see the recipe button and it will lead you to variety of recipes for the menu. Next select the recipe you want to make, and recipe site will be show.

• Kakao Map API - When user selects a menu, Kakao Map Api will search the menu in Kakao Map near where you are. Providing restruant information.

3. UI

Fixes

• Recipe TableView loading problem.

Original image fetching code.

  
   let url = URL(string: imageBaseUrl + decodedData!.results[indexPath.row].image)
        let data = try! Data(contentsOf: url!)
        cell.foodThumNail.image = UIImage(data: data)
   
   

Fixed image fetching code.

 
  private func fetchImage() {
        if let url = thumnailUrl {
            DispatchQueue.global(qos: .userInitiated).async { [weak self] in
                let urlContents = try? Data(contentsOf: url)
                DispatchQueue.main.async {
                    if let imageData = urlContents {
                        if let imag = UIImage(data: imageData){
                            self?.foodThumNail.image = imag
                        }else{
                            print("no image available")
                        }
                    }
                }
            }
        }
    }
    
    var thumnailUrl : URL?{
        didSet {
            if thumnailUrl != nil && (oldValue != thumnailUrl) {
                fetchImage()
            }
        }
    }
    
    cell.thumnailUrl = URL(string: imageBaseUrl + decodedData!.results[indexPath.row].image)
