DBChooser in Swift3 app - DirectLink = "nil" problem

[mohergryzie]

Hi,

I'm using DBChooser framework for pdf preview and download from dropbox and then to upload to another server. I stuck on this part of code.

ViewController

DBChooser.default().open(for: DBChooserLinkTypeDirect, from: self, completion: { reasults in print(reasults as Any) })

DBChooser is working because dropbox is opening and then returning to the app. Hovever it is not holding direct link in directory.

let downloadURL = DBChooserResult()
            print(downloadURL.link)
#nil

AppDelegate

 func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool {
        
        if (DBChooser.default().handleOpen(url as URL!)) {
            return true
        }
        return false
    }

Any ideas what is wrong?

You appear to be constructing your own DBChooserResult object instead of using the one(s) in the results array returned by Dropbox. You should instead do something like this:

DBChooser.default().open(for: DBChooserLinkTypeDirect, from: self, completion: { results in

    if ((results?.count) != 0) {
        for case let result as DBChooserResult in results! {
            print(result.link)
        }
    } else {
        print("no results")
    }

})

Greg, Thank you, but it is still not working. There are no errors but still result of print(result.link) is "". 

for case let result as DBChooserResult in results! {
                    print(result.link)
                    MyVariables.fullpdfURL = String(describing: result.link)

I put some code to set my global variable and it is still "nil".

Thanks for following up. The code I shared worked properly for me, so we'll have to look into this further. Can you let me know:
- the version number of the Chooser SDK you have
- the version number of the official Dropbox iOS app you have installed

Greg thanks for response! My app is simply not handling value. I have the newest DBChooser SDK - installed via Cocoa Pods. Dropbox version is 44.2.2.

Thanks! I actually tested on 44.2.4 though, so can you try upgrading and letting me know if that helps?

Also, I'm not sure I understand what you mean when you say your "app is simply not handling value". Can you elaborate? Thanks in advance!
