我想把导航栏的背景设置为黑色,里面的所有颜色都是白色。

所以,我使用了这段代码:

[[UINavigationBar appearance] setTitleTextAttributes:
     [NSDictionary dictionaryWithObjectsAndKeys:
      [UIColor whiteColor],
      NSForegroundColorAttributeName,
      [UIColor whiteColor],
      NSForegroundColorAttributeName,
      [NSValue valueWithUIOffset:UIOffsetMake(0, -1)],
      NSForegroundColorAttributeName,
      [UIFont fontWithName:@"Arial-Bold" size:0.0],
      NSFontAttributeName,
      nil]];

但后退按钮的文本颜色,箭头和栏按钮仍然默认为蓝色。 如何改变这些颜色像下面的图像?

let textAttributes = NSMutableDictionary(capacity:1)
textAttributes.setObject(UIColor.whiteColor(), forKey: NSForegroundColorAttributeName)
navigationController?.navigationBar.titleTextAttributes = textAttributes

Swift / iOS8

let textAttributes = NSMutableDictionary(capacity:1)
textAttributes.setObject(UIColor.whiteColor(), forKey: NSForegroundColorAttributeName)
navigationController?.navigationBar.titleTextAttributes = textAttributes

Swift 5/iOS 13

更改控制器标题的颜色:

UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
[[UINavigationBar appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];

范的回答对我很管用。下面是c#开发者使用Xamarin.iOS/MonoTouch的相同解决方案:

var navigationBar = NavigationController.NavigationBar; //or another reference
navigationBar.BarTintColor = UIColor.Blue;
navigationBar.TintColor = UIColor.White;
navigationBar.SetTitleTextAttributes(new UITextAttributes() { TextColor = UIColor.White });
navigationBar.Translucent = false;

要改变UINavigationBar标题的颜色,正确的方法使用以下代码:

[self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:UITextAttributeTextColor]];

UITextAttributeTextColor在最新的ios 7版本中已弃用。使用NSForegroundColorAttributeName代替。
