iPhone上导航栏按钮的默认颜色是什么？ [英] What is the default color for navigation bar buttons on the iPhone?

问题描述

我在iPhone应用程式的导览列中新增分段控制项。默认情况下，分段控件的颜色与导航栏的颜色匹配。我想将分段控件的颜色与导航栏中的其他按钮（如后退导航按钮）匹配。

I'm adding a segmented control to a navigation bar in my iPhone app. By default the color of the segmented control matches the color of the navigation bar. I want to match the color of the segmented control to other buttons in the navigation bar (like the back navigation button).

任何人都可以告诉我一个RGB值

Can anyone tell me an RGB value (or a system color) that matches the default color of UIButtonBarItems that have been added to a UINavigationBar with a style of UIBarStyleDefault?

推荐答案

之后的UIButtonBarItems的默认颜色匹配UIButtonBarItems的默认颜色同时，我意识到iPhone正在对按钮应用蓝色渐变，所以色调需要非常灰。我终于打了这个HSV组合，这是完美的。请注意，根据文档，所有值都指定为0到1之间的浮点值。

After a while, I realized that the iPhone was applying a blue gradient to the button, so the tint needed to be pretty gray. I finally hit on this HSV combination which is pretty darn perfect. Note that as per the documentation, all values are specified as float values between 0 and 1.

Hue: 0.6

Saturation: 0.33

Value: 0.69

Alpha: 0

我希望这可以为其他一些开发人员节省几个小时的工作。

I hope this saves a couple hours of work for some other developer.
