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，其中的所有颜色都为白色。

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

所以，我使用了这段代码：

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]];

但后退按钮文字颜色，箭头 条形按钮仍有默认蓝色。

如何更改下图中的颜色？

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

$ b Apple文档 apple_ref / occ / instp / UINavigationBar / barTintColor> barTintColor 说：

---

Apple Documentation for barTintColor says :

默认情况下，此颜色为半透明，除非您设置
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;
