Question

我遇到一个奇怪的问题，隐藏然后显示UINavigationBar导致它将颜色变为永久黑色，因此我无法设置其颜色。

NaviationBar最初设置为灰色色调的简单示例：

// NavigationBar Colour is initially set - this works
[[UINavigationBar appearance] setBarTintColor:[UIColor red]];

// Then it is hidden and then shown
[self.navigationController setNavigationBarHidden:YES animated:NO];
....
[self.navigationController setNavigationBarHidden:NO animated:NO];

状态栏色调颜色现在为黑色，无法通过设置外观或直接设置颜色来更改。

任何人都可以解释这个并知道修复此问题的解决方案吗？

    When you set the color of navigation bar then put your appropriate code into **view Will appea**r and **View Will Disappear method**. When you do transition between view then it's set the Main view (Window) Navigation bar color. We discuss topic in this link.
