Hello @J-Arji, Thanks for using this library! :)

Can you show the code where you are using the DropDown?
How have you imported this library, manually, via Cocoapods or Carthage?
Are you using DropDown in Objective-C ?

[J-Arji]

i import with cocoapods an using in swift

code:

      dropDown.dataSource = [
            "Car",
            "Motorcycle",
            "Van",
            "Truck",
            "Bus",
            "Bicycle",
            "Feet"
        ]

            dropDown.selectionAction = { [unowned self] (index, item) in
            self.actionButton.setTitle(item, forState: .Normal)
                let lit = item
                print(lit)
        }

        dropDown.direction = .Bottom
        dropDown.anchorView = actionButton
        dropDown.bottomOffset = CGPoint(x: 0, y:actionButton.bounds.height)
        // returns a String?




    }


    @IBAction func ActionTypeAir(sender: AnyObject) {

        if dropDown.hidden {
            dropDown.show()
        } else {
            dropDown.hide()
        }

Thanks for the follow-up! 👍

So the only line that's causing problem seems to be

dropDown.anchorView = actionButton

Did you try compiling with this line in comment?

Hey @kevin-hirsch I just updated to v1.0 (congrats on the full release) and using your pod from an Objective-C view controller I experience this issue also. It appears that the anchorView property is not visible to Objective-C. I suspect because it is an Optional of a non-Objective-C type: http://stackoverflow.com/questions/26366082/cannot-access-property-of-swift-type-from-objective-c

[markedwardmurray]

Adding @objc before the protocol definition in line 18 allows it to build:

@objc public protocol AnchorView: class {

    var plainView: UIView { get }

}

[kevin-hirsch]

Hello @markedwardmurray, thanks! :)
anchorView has the type:

public protocol AnchorView: class {
    var plainView: UIView { get }
}

Did you try adding an @objc above the protocol?

[kevin-hirsch]

Ok, perfect! I'll add this now 👍

[markedwardmurray]

Yup, that's literally all it needs! I did have to avoid using the .bounds property on the anchorView from my view controller since it's now a type id, but that's no big deal.

[kevin-hirsch]

You can access the view through anchorView.plainView property, so for bounds, just do anchorView.plainView.bounds 😉

[markedwardmurray]

oh nice! thanks for the tip on that :)

[kevin-hirsch]

Done in 9d734e5. I will create a new version 1.0.1 for CocoaPods and Carthage.

[kevin-hirsch]

Actually, the reason I now use an AnchorView and not a UIView anymore is that I wanted to support UIBarButtonItems that are not UIView subclassed. So I implemented:

 extension UIView: AnchorView {
    public var plainView: UIView {
        return self
    }
 }

 extension UIBarButtonItem: AnchorView { 
    public var plainView: UIView {
        return valueForKey("view") as! UIView
    }
 }

So anchorView.plainView is the same as using anchorView before 1.0 🙃

[kevin-hirsch]

Version 1.0.1 available on CocoaPods and Carthage! 🎉

@J-Arji Can you confirm that you don't have the issue anymore?
I leave this issue open until your confirmation.

[J-Arji]

thanks @kevin-hirsch :) #

[GZaccaroni]

 extension UIBarButtonItem: AnchorView { 
    public var plainView: UIView {
        return valueForKey("view") as! UIView
    }
 }

doesn't work anymore in iOS 11.
Access to a private API can lead to a app being refused during the apple app store review process.
My suggestion is to delete the extension @kevin-hirsch
