How can I find out the RGB color of my object in storyboard
提问by Esqarrouth
I have a button in the storyboard, I gave it a color magnesium. I am doing some programming on the button which will change its color on certain situations.
我在故事板中有一个按钮，我给了它一个彩色镁。我正在对按钮进行一些编程，该按钮会在某些情况下改变其颜色。
I like the original color of the button in the storyboard and I want to return back to that color at some event.
我喜欢故事板中按钮的原始颜色，我想在某个事件中恢复到那个颜色。
Now the problem is that color I am using doesn't have a text name (yellowcolor, purplecolor) in UIColor and I can't find the RGB values from the storyboard color picker.
现在的问题是我使用的颜色在 UIColor 中没有文本名称（黄色、紫色），而且我无法从故事板颜色选择器中找到 RGB 值。
Any ideas?
有任何想法吗？

Xcode->选择对象->属性检查器->文本颜色->其他->颜色滑块->下拉菜单->RGB滑块

You can do this to get the RBG from UIColor:
您可以这样做以从 UIColor 获取 RBG：
CGFloat red = self.btn.backgroundColor.CIColor.red;
CGFloat blue = self.btn.backgroundColor.CIColor.blue;
CGFloat green = self.btn.backgroundColor.CIColor.green;
CGFloat alpha = self.btn.backgroundColor.CIColor.alpha;
