iOS 7 导航栏文本和箭头颜色 [英] iOS 7 Navigation Bar text and arrow color

问题描述

我想将导航栏的背景设置为黑色，并将其中的所有颜色设置为白色.

I want to set background for Navigation Bar to be black and all colors inside it to be white.

所以，我使用了这个代码:

So, I used this code :

[[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]];

但是后退按钮文字颜色、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?

But back button text color, arrow and bar button have still default blue color.
How to change those colors like on image below?

Apple 文档，用于 barTintColor 说:

默认情况下这种颜色是半透明的，除非你设置半透明属性为NO.

This color is made translucent by default unless you set the translucent property to NO.

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;
