故事板中的颜色与 UIColor 不匹配 [英] Color in storyboard not matching UIColor

问题描述

我将代码中的颜色定义为

I am defining a color in code as

[UIColor colorWithHue:32.0/360.0 saturation:0.88 brightness:0.97 alpha:1]

如果我尝试在情节提要中设置相同的颜色，则在运行应用程序时，它的颜色与代码中定义的颜色略有不同.如果我将颜色拖到上颚然后选择不同的颜色并再次选择上颚，HSB 值会略有不同.它似乎在界面构建器中捕捉到不同的(RGB?)颜色.

If I try to set the same color in storyboard, when running the App it is a slightly different colour to the one defined in code. If I drag the color to the palate then select a different color and select the palate one again, the HSB values are slightly different. It seems it is snapping to a different (RGB?) color in interface builder.

推荐答案

Xcode 8+, iOS 10+

我最近遇到了这个问题，但发布的答案都没有.事实证明，随着 iOS 10 SDK 的发布，UIColor 初始值设定项 init(red:green:blue:alpha:) 现在使用扩展的 sRGB 范围，因此您有在 Storyboard 上配置颜色值时进行相应设置.

I recently faced this problem and none of the posted answers did it. It turns out that with the release of iOS 10 SDK, the UIColor initializer init(red:green:blue:alpha:) now uses the extended sRGB range, so you have to set accordingly when configuring your color values on the Storyboard.
