InputAccessoryView UIToolbar turns black when rotating in iOS

Question

Here is my code:

override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. let keyBoardToolBar = UIToolbar(frame: CGRectMake(0, 0, self.view.frame.size.width, 44)) keyBoardToolBar.barStyle = .Default let flexSpaceKeyboardBarButtonItem = UIBarButtonItem(barButtonSystemItem: .FlexibleSpace, target: nil, action: nil) let doneKeyboardBarButtonItem = UIBarButtonItem(title: "Done", style: .Done, target: self, action: nil) let wordKeyboardBarButtonItem = UIBarButtonItem(title: "Button 1", style: .Plain, target: self, action: nil) var barItems: [UIBarButtonItem] = [] barItems.append(wordKeyboardBarButtonItem) barItems.append(flexSpaceKeyboardBarButtonItem) barItems.append(doneKeyboardBarButtonItem) keyBoardToolBar.setItems(barItems, animated: true) self.myTV.inputAccessoryView = keyBoardToolBar } 

And when I rotate the device, the UIToolBar turns black: (click to see this GIF again)

Anyway, to fix it? Thanks!

BTW: In the simulator, I do not see how the UIToolBar turns black.

Answer 1

Fixed by adding: (still unclear about the reason causing it)

 keyBoardToolBar.isTranslucent = false keyBoardToolBar.barTintColor = UIColor(colorLiteralRed: (247/255), green: (247/255), blue: (247/255), alpha: 1) 

( UIColor(colorLiteralRed: (247/255), green: (247/255), blue: (247/255), alpha: 1) - this is the default background color for the UIToolBar from here )
