Try this : (You need to implement UIDocumentInteractionControllerDelegate)

func documentInteractionControllerViewControllerForPreview(_ controller: UIDocumentInteractionController) -> UIViewController {
    return self.navigationController ?? self
}

It's a little hacky as its relying on the fact that QLPreviewController is the class implementing the UIDocumentInteractionController but something like this is the least intrusive solution. Do it before you display the UIDocumentInteractionController

import QuickLook

UIBarButtonItem.appearance(whenContainedInInstancesOf [QLPreviewController.self]).tintColor = UIColor.black

     let QLNavAppearance = UINavigationBar.appearance(whenContainedInInstancesOf: [QLPreviewController.self])
    QLNavAppearance.tintColor = UIColor.red // some
    QLNavAppearance.barTintColor =  UIColor.red // some
    QLNavAppearance.backgroundColor =  UIColor.red // some

I solved it. Here is the code working for me perfectly:

func documentInteractionControllerViewControllerForPreview(_ controller: UIDocumentInteractionController) -> UIViewController {
    UINavigationBar.appearance().barTintColor = Colors.redColor()
    UINavigationBar.appearance().tintColor = UIColor.white
    UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.white, NSFontAttributeName: UIFont.systemFont(ofSize: 14, weight: UIFontWeightBold)]
    return self
}

@Dee. I guess you have asked this part in one of your other question. In that case you were not able to show that preview controller. In that question suggested answer is to return "self" from that delegate method. If you implement that correctly then your preview will use same navigation bar colour as its parent controller is using. I mean if you have opened UIDocumentInteractionController directly from some ViewController then UIDocumentInteractionController will use its parent viewController's navigation bar colour. This may help you to change Done button colour

You can change the tint color of the window temporally.

func presentDocument() {
    //present the controller here
    self.appDelegate.window.tintColor = UIColor.red
}

Then change it back later:

func documentInteractionControllerDidEndPreview(documentInteractionController) { //replace parameter with your uidocumentviewinteractioncontroller
    self.appDelegate.window.tintColor = UIColor.white
}

I have a idear to change the bar color:

let allNavigationBar = UINavigationBar.appearance()
allNavigationBar.barTintColor = UIColor.red  // change the bar background color
allNavigationBar.tintColor = UIColor.black // change the Done button's tintColor

let alloolbar = UIToolbar.appearance()
allToolbar.barTintColor = UIColor.red  // dones't work, try backgroundImage
allToolbar.backgroundColor = UIColor.blue // dones't work
allToolbar.tintColor = UIColor.brown // change the toolbar's item tint color

but this method has a great effect，all your UINavigationBarand UIToolBar will make that change.

Hope anyone else can give a better solusion.
