iOS7中奇怪的UITabBar颜色不一致 [英] weird UITabBar color inconsistency in iOS7

问题描述

我正在使用iOS 7的 tintColor 和 barTintColor 属性来为我的 UITabBar着色在UITabBarController的子类中使用此代码：

I'm using iOS 7's tintColor and barTintColor properties to color my UITabBar with this code in a subclass of UITabBarController:

[[UITabBar appearance] setBarTintColor:[UIColor colorWithRed:123/255.0 green:47/255.0 blue:85/255.0 alpha:1]];
[[UITabBar appearance] setTintColor:[UIColor colorWithRed:227/255.0 green:180/255.0 blue:204/255.0 alpha:1]];

在三个屏幕上，颜色是我想要的颜色（只有两个图像说明了这一点）：

On three screens, the color is what I want it to be (only two images illustrating this):

一个屏幕，颜色非常轻。此屏幕是 UIWebView 。

One one screen, the color is weirdly lighter. This screen is a UIWebView.

然后在第四个屏幕上，颜色为SUPER-light。这个屏幕是唯一一个使用故事板的人 - 其余的都是以编程方式完成的。

Then on a fourth screen, the color is SUPER-light. This screen is the only one to use a storyboard--the rest are all done programmatically.

我做错了什么？事实上，行为不当的屏幕是 UIWebView ，故事板与他们行为不端的原因有什么关系？我该如何解决它们？我已经摆弄了酒吧的阿尔法，但它并没有改变任何东西。

What am I doing wrong? Do the fact that the misbehaving screens are a UIWebView and a storyboard have anything to do with why they're misbehaving? And how do I fix them? I've fiddled with the alpha of the bar but it doesn't change anything.

感谢您的帮助。

推荐答案

您正在看标签酒吧半透明...即背景视图正在渗透和模糊。如果你想禁用它，你可以这样做：

You're seeing tab bar translucency...i.e. the background view is bleeding through and being blurred. If you want to disable this, you can do:

[tabBar setTranslucent:NO]

在标签栏上。

在你的前两张图片中，它不清楚对我来说，如果基础视图控制器视图是边对边的，即你的前两个图像应该看起来像第四个，因为它们都是粉红色背景。无论如何，setTranslucent：NO应该让它们看起来像顶部图像。

On your top two images, its not clear to me if the underlying view controller view is edge-to-edge, i.e. your top two images should look like the fourth one since both have pink backgrounds. Anyhow, setTranslucent:NO should make them all look like the top image.
