I'm developing an app using Dropdowns the app works fine on my iOS version 11.4, but when i try on a device on version 10.3 the app gets lock i don't know why.

the scenery is this:
I have two options in my dropdown, when i check the second one (Ranking popularidad) the tableview reloads great and shows the information and you can scroll down and scroll up, then I do click on a cell and show the profile of the place, then when i get back clicking on the link Atrás the application get lock, any help

let titleView = TitleView ( navigationController: navigationController!, title: "", items: items, defaultIndex: 0)

`open class TitleView: UIView {

open var dropdown: DropdownController!
open var button: ArrowButton!
open var action: ((Int) -> Void)?

// MARK: - Initialization

public init?(navigationController: UINavigationController, title: String, items: [String], defaultIndex: Int) {
super.init(frame: CGRect.zero)

// Button
button = ArrowButton()
button.label.text = title
button.label.text = items[defaultIndex]
button.addTarget(self, action: #selector(buttonTouched(_:)), for: .touchUpInside)
addSubview(button)
self.layoutSubviews()

// Content
let contentController = TableController(items: items, initialIndex: defaultIndex )

// Dropdown
guard let dropdown = DropdownController(contentController: contentController, navigationController: navigationController)
  else { return nil }

self.dropdown = dropdown

contentController.action = { [weak self, weak dropdown] index in
  self?.button.label.text = items[index]
  self?.action?(index)
  self?.layoutSubviews()
  dropdown?.hide()
}

contentController.dismiss = { [weak dropdown] in
  dropdown?.hide()
}

dropdown.animationBlock = { [weak self] showing in
  self?.button.arrow.transform = showing
    ? CGAffineTransform(rotationAngle: CGFloat.pi) : CGAffineTransform.identity
}

}

public required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}

open override func layoutSubviews() {
super.layoutSubviews()
button.label.sizeToFit()
button.frame.size.height = 44
button.sizeToFit()
frame.size = button.frame.size
}

// MARK: - Action

@objc func buttonTouched(_ button: ArrowButton) {
dropdown.toggle()
}
}
`

let titleView = TitleView(navigationController: navigationController!, title: "Menu", items: ["World", "Sports", "Culture", "Business", "Travel","jawad"]) here why ?

Fatal error: Unexpectedly found nil while unwrapping an Optional value

Please change below in DropdownController

let offsetY = UIApplication.shared.statusBarFrame.size.height + navigationController.navigationBar.frame.height

This project isn't compatible with Swift 4 / XCode 9 Release.

I am setting up Dropdowns in my project using cocoapods. But I can't see the initial index parameter to 'TitleView'. I guess it was added recently.

Does the POD name change?

hi, i am trying to change the color of the view that is behind the tableview that is now set to some sort of green (the view that u see when u scroll down). is there a way to do that?

Hey, I would like to have the possibility to change the default arrow image in the title via Config. #

There is an invalid layout on iPhone 7 simulator with iOS 10.3 (Xcode 9.1)

The source you wrote is very useful to me
But, i have a question.
How can i set selected menu in programmatically?

Hi There,

When I enter in background mode my app crashes due memory leak. I Comment the following code:

let titleView = TitleView(navigationController: nav, title: company.company_name, items: companies)
            titleView?.button.label.textColor = .white
            titleView?.button.arrow.image = titleView?.button.arrow.image?.withRenderingMode(.alwaysTemplate)
            titleView?.button.arrow.tintColor = .white
            titleView?.action = { [weak self] index in
              print("select \(index)")
                let company_name = companies[index]
                let company = user.companies.filter({ $0.company_name == company_name }).first
                self?.selectedCompany = company
                titleView?.button.label.textColor = .white
                titleView?.button.arrow.image = titleView?.button.arrow.image?.withRenderingMode(.alwaysTemplate)
                titleView?.button.arrow.tintColor = .white
                AppSessionManager.shared.retrieveProducts = false
                AppSessionManager.shared.retrieveOrders = false
                NotificationCenter.default.post(name: NSNotification.Name(rawValue: "companyChange"), object: nil)
            }
            navigationItem.titleView = titleView

Now my app does not have memory leaks. What could be happening?

Best regards

So. I integrated Dropdowns into my project and it worked fine until I started to work on landscape orientations. Every time I try to change orientation of simulator or even real device - app freezes forever and takes 100% cpu. Was hard for me to detect what part of app does actually crash it, but after all I found that without Dropdowns app doesn't show that bug

Hi, is there a way to detect if the dropdown menu is currently showing? (after the arrow button is pressed and before the selection is made).

Thanks,

Can't seem to find the podfile

When I try to compile it and integrate it with Swift 4.1, I cannot import this module, since it was compiled with Swift 4.0.3.

Does this support swift 4.2?
