Swift导航栏背景颜色白色不起作用

问题描述

我很难将 navigationBar.barTintColor 更改为白色.奇怪的是，所有其他颜色都可以，但不是白色！

Im having a difficult time trying to change the navigationBar.barTintColor to white. Strangely, all other colors work, but not white!

self.navigationController!.navigationBar.barTintColor = UIColor.whiteColor()

以上行不适用于白色.

甚至尝试使用背景图片.还是一样.任何其他颜色都可以，但不是白色！！白色总是被浅灰色代替...

Even tried with a background image. Still the same. Any other color works but not white!! White is always replaced by light grey...

请指教我哪里出错了...

Please advice where I am going wrong...

谢谢.

推荐答案

试试这个代码:

在你看来DidLoad:

In your viewDidLoad:

    title = "Some Title"

    UIApplication.shared.statusBarStyle = .default
    navigationController?.navigationBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
    navigationController?.navigationBar.shadowImage = UIImage()
    navigationController?.navigationBar.isTranslucent = true

    //Line under NavigationBar
    let barView = UIView(frame: CGRect(x:0, y:(UINavigationController().navigationBar.frame.height + UIApplication.shared.statusBarFrame.height), width:view.frame.width, height:0.6))
    barView.backgroundColor=UIColor.red // set any colour you want..
    navigationController?.navigationBar.addSubview(barView)

    //Title Colour
     navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName:UIColor.red]

注意:

以上代码适用于任何背景颜色....如果您希望导航栏为绿色....将您的视图背景颜色设置为绿色...

Above code works on any background colour.... If you want the navigationBar to be green....set your view background colour to green...
