SwiftyDropBox SwiftyDropbox.MobileSafariViewController not in the window hierarchy
Hi, I have developed an application in Xcode (macOS) for iOS and I have integrated the SwiftyDropBox API. I have followed all the instructions in the README, but when I make a call to open a link to DropBox I get the following error.
Warning: Attempt to present <SwiftyDropbox.MobileSafariViewController: 0x7fb17981d800> on <Scipple_V2_0.ViewController: 0x7fb177c29d00> whose view is not in the window hierarchy!
I have Googled this to death but can't find an answer.
The initial DropboxClientsManager.setupWithAppKey seems to work (I am using the App Key I get from the App Console in DropBox.
Can anyone give me any suggestions how to fix this?
Thanks
Neil
Hi,
I think you're right but not sure what I was doing wrong, the call is in my viewcontroller, however I tried
DropboxClientsManager.authorizeFromController(UIApplication.shared, controller: UIApplication.shared.keyWindow!.rootViewController!, openURL: { (url: URL) -> Void in UIApplication.shared.open(url, options: [:], completionHandler: nil) })
i.e. using rootViewController instead of self and it worked.
Thanks for your response

This error message generally indicates that the authorization window can't be displayed because it relies on yourViewController, but theViewController wasn't in the window hierarchy (yet?) at time of the call. Perhaps your ViewController wasn't presented (or was already dimissed) at the time?
