在iOS中旋转时,inputAccessoryView的UIToolbar变黑

概述这是我的代码： override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. let keyBoardToolBar = UIToolbar(frame: CGRectMake(0, 0, 这是我的代码：

overrIDe func vIEwDIDLoad() {    super.vIEwDIDLoad()    // Do any additional setup after loading the vIEw,typically from a nib.    let keyBoardToolbar = UIToolbar(frame: CGRectMake(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,action: nil)    var barItems: [UIbarbuttonItem] = []    barItems.append(wordKeyboardbarbuttonItem)    barItems.append(flexSpaceKeyboardbarbuttonItem)    barItems.append(doneKeyboardbarbuttonItem)    keyBoardToolbar.setItems(barItems,animated: true)    self.myTV.inputAccessoryVIEw = keyBoardToolbar}

当我转动设备时,UIToolbar变黑了(点击再次查看此GIF)

那么无论如何要修复它？谢谢！

顺便说一句：在模拟器中,我看不到UIToolbar变黑了.

解决方法 通过添加修复:(仍然不清楚导致它的原因)

keyBoardToolbar.isTranslucent = falsekeyBoardToolbar.barTintcolor = UIcolor(colorliteralRed: (247/255),green: (247/255),blue: (247/255),Alpha: 1)

(UIcolor(colorliteralRed：(247/255),绿色：(247/255),蓝色：(247/255),Alpha：1)是从here开始的UIToolbar的默认背景颜色)
