It is showing "Unable to find a specification for YNDropDownMenu" while installing pod. My project's deployment target is 9.0. What is the issue?

I have installed the most recent version of YNDropDownMenu however i got this error "/Users/x/Documents/IOS development/Kallos/Pods/YNDropDownMenu/YNDropDownMenu/YNDropDownMenu.swift:583:43: 'init(colorLiteralRed:green:blue:alpha:)' is unavailable: This initializer is only meant to be used by color literals"

I need change the top menu backgroundColor to clear, you said use YNDropDownButton in issue15, but YNDropDownButton is not public, I can't use it by Carthage. I need this:

안녕하세요! 멋진 오픈소스 만들어주셔서 감사합니다 :) YNDropDownMenu를 사용하면서 입맛에 맞게 조금 변경한점을 풀리퀘 보냅니다ㅎㅎㅎ (풀리퀘가 처음이라 이런식으로 하는게 맞는지 모르겠네요 ㅎㅎ...)

변경사항은 아래와 같습니다!!

1. 스위프트 4.2로 업데이트
2. flatmap -> compactmap 으로 변경
3. 드롭다운 arrow 이미지 대신 각각의 이미지 적용 기능 추가(setImageWhens)

Is there a way to have multiple titles on the YNDropDownMenu that can be scrolled horizontally? For example, instead of having only Apple, Banana, Kiwi and Pear, I could add 5 more and have them displayed by scrolling horizontally.

Hi,

Very nice dropdown :-)

Im trying to change the YNDropDownMenu backgroundColor to UIColor.white.withAlphaComponent(0.0), I can't find where to do this, any suggestions?

Thanks Bennie

remove setImageWhen(normal: UIImage?, selectedTintColor: UIColor, disabledTintColor: UIColor), setImageWhen(normal: UIImage?, selectedTintColorRGB: String, disabledTintColorRGB: String) functions; replace setImageWhen(normal: UIImage?, selected: UIImage?, disabled: UIImage?) with setStatesImages(normalImages: [UIImage?], selectedImages: [UIImage?], disabledImages: [UIImage?]); update Demo, README.

I placed YNDropDownMenu inside a UIView, it seems to be hid when DropDownViews show up. Any way to solve this?

Structures:

• ViewController +- View +-- PageMenu:UIView +--- YNDropDownMenu

Code:

@IBOutlet weak var pageMenu: UIView!

let menuView = YNDropDownMenu(frame: CGRect(x: 0, y: 0, width: self.pageMenu.frame.width, height: self.pageMenu.frame.height), dropDownViews: _customerDropViews, dropDownViewTitles: ["Menu1", "Menu2", "Menu3"])
  
let FFA409 = UIColor.init(red: 255/255, green: 164/255, blue: 9/255, alpha: 1.0)
menuView.setImageWhen(normal: UIImage(named: "arrow_nor"), selected: UIImage(named: "arrow_sel"), disabled: UIImage(named: "arrow_dim"))
menuView.setImageWhen(normal: UIImage(named: "arrow_nor"), selectedTintColor: FFA409, disabledTintColor: FFA409)
menuView.setImageWhens(normal: [UIImage(named: "arrow_nor"),UIImage(named: "arrow_nor"),UIImage(named: "arrow_nor")], selectedTintColorRGB: "FFA409", disabledTintColorRGB: "D3D3D3")
menuView.setLabelColorWhen(normal: .gray, selected: menuFontColor, disabled: .black)
menuView.setLabelFontWhen(normal: .systemFont(ofSize: 14), selected: .systemFont(ofSize: 14), disabled: .systemFont(ofSize: 14))
menuView.bottomLine.isHidden = false
menuView.bottomLine.backgroundColor = UIColor.init(red: 224/255, green: 224/255, blue: 224/255, alpha: 1)

pageMenu.addSubview(menuView)

In Swift4, a declaration within an NSObject-derived class will no longer infer @objc. https://github.com/apple/swift-evolution/blob/master/proposals/0160-objc-inference.md

When I used your component with clear background color I have noticed stange effect. dropDownView to bland with menu, but for second show menu this problem doesn't reproduce. I think you have refused change position, but In initViews() you forget this remove.

I am making the pull request.

라이브러리를 사용하다가 제가 필요한 기능이 몇개 수정해본것을 풀리퀘 넣어봅니다~

수정된 사항은 1. 컬러마스킹 기능, 2. Hex 컬러 String값을 UIColor로 바꾸는 function 두가지를 setImageWhen 부분과 setLabelColorWhen 부분에 적용해보았습니다.

혹시 문제되는 사항이 있으시다면 수정해주시거나 리뷰부탁드립니다. :) 감사합니다.

Looking for setting the menu background color as clear Color. It is showing white color only. Tried with the demo project as well.

view.setBackgroundColor(color: UIColor.clear)

As an objective looking to be have one dropdown button on text field. On opening it will show search filter form within dropdown view.

I am wanting to implement a table view, which is populated by an API, in the drop down. I added a table to the XIB file and created another XIB file for the table cell.

Primary View Controller:

class EcardSingleCategoryViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate, UICollectionViewDelegateFlowLayout {

var ecards = Content
let imageCache = NSCache<NSString,AnyObject>()

@IBOutlet weak var ecardCollection: UICollectionView!

var name = ""
var id = ""

override func viewDidLoad() {
    super.viewDidLoad()
    
    let ZBdropDownViews = Bundle.main.loadNibNamed("EcardCategories", owner: nil, options: nil) as? [UIView]
    let view = YNDropDownMenu(frame:CGRect(x: 0, y: 64, width: UIScreen.main.bounds.size.width, height: 64), dropDownViews: ZBdropDownViews!, dropDownViewTitles: ["Choose Category"])

   self.view.addSubview(view)
}

In the initViews() function, I get the following error ... for the "categoryTable.register( ... " code

Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value

I'm not sure how I would go about calling the cell's XIB file and populate the data.

Drop Down code:

class EcardCategoriesMenu: YNDropDownView {

@IBOutlet var categoryTable: UITableView!

var categories = [CategoryItem]()

override init(frame: CGRect) {
    super.init(frame: frame)
    self.initViews()
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    
    self.initViews()
}

func initViews() {
    
  //  categoryTable.register(UINib(nibName: "EcardCategoriesCell", bundle: nil), forCellReuseIdentifier: "EcardCategoriesCell")
    
    categoryTable.delegate = self
    categoryTable.dataSource = self
    
    DispatchQueue.main.async {
        let jsonUrlString = "https://*****/category"
        guard let url = URL(string: jsonUrlString) else { return }

        URLSession.shared.dataTask(with: url) { (data, response, err) in
            guard let data = data else { return }
            
            if err == nil {
                do {
                    let decoder = JSONDecoder()
                    let ecardcategory = try decoder.decode(Category.self, from: data)
                    self.categories = ecardcategory.category
                    self.categories.sort(by: {$0.title < $1.title})
                } catch let err {
                    print("Err", err)
                }
                
                DispatchQueue.main.async {
                    print(self.categories.count)
                    self.categoryTable.reloadData()
                }
            }
        }.resume()
    }
}
}
extension EcardCategoriesMenu: UITableViewDelegate, UITableViewDataSource {

func numberOfSections(in tableView: UITableView) -> Int {
    return 1
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return categories.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    guard let cell = tableView.dequeueReusableCell(withIdentifier: "EcardCategoriesCell", for: indexPath) as? EcardCategoriesCell else { return UITableViewCell() }
    cell.categoryName.text = ("\(categories[indexPath.row].title)")
    return cell
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let mainStoryboard:UIStoryboard = UIStoryboard(name: "Ecard", bundle: nil)
    let desVC = mainStoryboard.instantiateViewController(withIdentifier: "EcardSingleCategoryViewController") as! EcardSingleCategoryViewController
    desVC.id = String(categories[indexPath.row].id)
    let navigationController = UIApplication.shared.keyWindow?.rootViewController as! UINavigationController
    navigationController.pushViewController(desVC, animated: true)
}
}

Cell Code:

class EcardCategoriesCell: UITableViewCell {
    @IBOutlet weak var categoryName: UILabel!
}

Any help sorting through this would be great.

// filterView.snp.makeConstraints { (make) in // make.top.equalTo(64) // make.left.right.equalTo(view) // make.height.equalTo(38) // } I'm using SnapKit, the label of menu displays on top offset about half of height. pls check it.

From what I can tell, by adding a YNDropDownMenu to my view, it creates three subviews for the items, the view to be toggled, and a background faded view.

Everything works great if the user does not change their screen orientation, but if they do, the menu and it's three created views do not update their dimensions.

I've tried manually adding constraints myself, but they only target one of the three views, and I have no way to access the other two views created to add constraints to them as well. Help?
