當它的bg顏色設置爲黑色時，UINavigationBar是白色

Question

我不明白它爲什麼如此。這裏是我的代碼：

UINavigationBar.appearance().backgroundColor = UIColor.blackColor() 
UINavigationBar.appearance().translucent = false 

Answer 1

變化backgroundColor到barTintColor和

試試這個

UINavigationBar.appearance().barTintColor = UIColor.blackColor() 
UINavigationBar.appearance().translucent = false 

e.g

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool 
{ 
    UINavigationBar.appearance().barTintColor = UIColor.blackColor() 
    UINavigationBar.appearance().translucent = false 

    return true 
} 

或使用

self.navigationController!.navigationBar.barTintColor = UIColor.blackColor() 
    self.navigationController!.navigationBar.translucent = false 

e.g

override func viewDidLoad() { 
    super.viewDidLoad() 

    self.navigationController!.navigationBar.barTintColor = UIColor.blackColor() 
    self.navigationController!.navigationBar.translucent = false 

     }
