Hello,

When I added UIDropDown inside my UICollectionViewCell. It can not be selected. It doesn't response to user tap or click.

class MyCell: UICollectionViewCell {
    override init(frame: CGRect) {
        super.init(frame: frame)
        setupViews()
    }
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    setupViews(){
        drop = UIDropDown(frame: CGRect(x: 0, y: 0, width: 80, height: 30))
        drop.center = CGPoint(x: 0, y: 0)
        drop.placeholder = "select your country"
        drop.options = ["Mexico", "USA", "England", "France", 
        drop.didSelect { (option, index) in
            print("You just select: \(option) at index: \(index)")
        }
        drop.tableHeight = 200
        drop.hideOptionsWhenSelect = true
        drop.animationType = UIDropDownAnimationType(rawValue: 0)!
        addSubview(drop)
    }
}

I've used UIDropDown in my other project. It works really great. Thanks you! But I don't know what I'm doing wrong in this case.

I used these two functions a lot (hundreds of times throughout my projects) but it seems that the functions are no longer available? I can't find a reasonable solution or workaround meaning that my project no longer work.

Why were these functions pulled?

Were they replaced with something?

Thanks

I believe that there is an issue which makes the text alignment dependent on the "View As" selection made it xCode. This means that it will not be possible to make the drop down appear correctly on both an iPhone and iPad at the same time.

To clarify, this is only an issue when you specify leading and trailing widths to say superview. If instead, you were to center the UIDropdown on the x axis and explicitly specify the width then you would have no issue, but you would have a small dropdown on an iPad

The below change appears to have fixed the issue, I have used screenSize.width rather than self.frame.width

    fileprivate func setup() {
    let screenSize: CGRect = UIScreen.main.bounds
    let screenWidth = screenSize.width
    let screenHeight = screenSize.height
    title = UILabel(frame: CGRect(x: 0,
                                  y: 0,
                                  width: (screenWidth-self.frame.height),
                                  height: self.frame.height))

    title.textAlignment = .center
     print("\(self.frame.width)")
    print("\(screenWidth)")
    self.addSubview(title)

There may be a way to specify the object width when the dropdown is set up. I tried but it didnt affect the actual size of self.frame.width inside the UIDropDown class

dropDown1.frame = CGRect(x: 0, y:0, width: self.view.frame.width, height: self.view.frame.height)
    dropDown1.center = CGPoint(x: self.view.frame.midX, y: self.view.frame.midY)

If there is a way to use your original code but specify the width so that self.frame.width is not dependent on the Storyboard "view as" device type then could you please tell me how to do that?
