提问by 1110
I want to set background for Navigation Bar to be blackand all colors inside it to be white.
我想将 Navigation Bar 的背景设置为black ，并将其中的所有颜色设置为white。
So, I used this code :
所以，我使用了这个代码：
[[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]];
But back button text color, arrowand bar buttonhave still default blue color.
How to change those colors like on image below?
但是后退按钮的文字颜色、箭头和条形按钮仍然是默认的蓝色。
如何更改如下图所示的颜色？

Apple Documentationfor barTintColorsays :
苹果文档的barTintColor说：
This color is made translucent by default unless you set the translucent property to NO.
默认情况下，此颜色是半透明的，除非您将半透明属性设置为 NO。
Sample Code :
示例代码：
self.navigationController.navigationBar.barTintColor = [UIColor blackColor];
self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
[self.navigationController.navigationBar
setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];
self.navigationController.navigationBar.translucent = NO;

This one took me about half a day to figure out but this is what worked for me. Inside the rootViewController that initializes the navigationController, I put this code inside my viewDidAppear method:
这个花了我大约半天的时间才弄明白，但这对我有用。在初始化 navigationController 的 rootViewController 中，我将此代码放在我的 viewDidAppear 方法中：
//set bar color
[self.navigationController.navigationBar setBarTintColor:[UIColor colorWithRed:85.0/255.0 green:143.0/255.0 blue:220.0/255.0 alpha:1.0]];
//optional, i don't want my bar to be translucent
[self.navigationController.navigationBar setTranslucent:NO];
//set title and title color
[self.navigationItem setTitle:@"Title"];
[self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:UITextAttributeTextColor]];
//set back button color
[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], UITextAttributeTextColor,nil] forState:UIControlStateNormal];
//set back button arrow color
[self.navigationController.navigationBar setTintColor:[UIColor whiteColor]];

To globally assign the color, in AppDelegate didFinishLaunchingWithOptions:
要全局分配颜色，请在 AppDelegate 中didFinishLaunchingWithOptions：
let textAttributes = [NSForegroundColorAttributeName:UIColor.white]
UINavigationBar.appearance().titleTextAttributes = textAttributes

Vin's answer worked great for me. Here is the same solution for C# developers using Xamarin.iOS/MonoTouch:
Vin 的回答对我很有用。以下是使用 Xamarin.iOS/MonoTouch 的 C# 开发人员的相同解决方案：
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;

To change color of UINavigationBartitle the correct way use this code:
要UINavigationBar以正确的方式更改标题的颜色，请使用以下代码：
[self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:UITextAttributeTextColor]];
UITextAttributeTextColoris deprecated in lastest ios 7 version. Use NSForegroundColorAttributeNameinstead.
UITextAttributeTextColor在最新的 ios 7 版本中已弃用。使用NSForegroundColorAttributeName来代替。

If you're looking to change the title text sizeand the text coloryou have to change the NSDictionary titleTextAttributes, for 2 of its objects:
如果您想更改标题文本大小和文本颜色，您必须更改 NSDictionary titleTextAttributes，为其 2 个对象：
self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Arial" size:13.0],NSFontAttributeName,
[UIColor whiteColor], NSForegroundColorAttributeName,
nil];

I think previous answers are correct , this is another way of doing the same thing. I am sharing it here with others just in case if it becomes useful for someone. This is how you can change the text/title color for the navbar in ios7:
我认为以前的答案是正确的，这是做同样事情的另一种方式。我在这里与其他人分享，以防万一它对某人有用。这是在 ios7 中更改导航栏的文本/标题颜色的方法：
UIColor *red = [UIColor colorWithRed:254.0f/255.0f green:0.0f/255.0f blue:0.0f/255.0f alpha:1.0];
NSMutableDictionary *navBarTextAttributes = [NSMutableDictionary dictionaryWithCapacity:1];
[navBarTextAttributes setObject:red forKey:NSForegroundColorAttributeName ];
self.navigationController.navigationBar.titleTextAttributes = navBarTextAttributes;

It seems that Accessibilitycontrols in the iOS Settingsoverride pretty much everything you try to do color-wise to the navigation bar buttons. Make sure you have all the settings to the default positions (set increase contrast, bold text, button shapes, etc to off) otherwise you won't see anything change. Once I did it, all the color change code started working as expected. You might not need to turn them all off, but I didn't pursue it further.
似乎覆盖中的Accessibility控件iOS Settings几乎覆盖了您尝试对导航栏按钮进行颜色明智的所有操作。确保您将所有设置都设置为默认位置（将增加对比度、粗体文本、按钮形状等设置为关闭），否则您将看不到任何变化。完成后，所有颜色更改代码都开始按预期工作。您可能不需要将它们全部关闭，但我没有进一步追求。
