我有以下代码：
UIColor *borderColor = [UIColor colorWithRed:182 green:10 blue:96 alpha:1.0];
[viewImage.layer setBorderColor:borderColor.CGColor];
[viewImage.layer setBorderWidth:3.0];
[productView addSubview:viewImage];
where viewImageis my UIImageViewand productViewis my UIView.
哪里viewImage是我的UIImageView，productView是我的UIView。
I want to get this color 
, but all I am getting is this color . I tried different values, and all the colors that I am getting is either white, red, black, yellow, or blue. I can't get any other colors, doesn't matter what values I enter. I tried colorWithHue:Saturation:Brightness and I have the same issue.
我想得到这种颜色，但我得到的只是这种颜色。我尝试了不同的值，我得到的所有颜色都是白色、红色、黑色、黄色或蓝色。我无法获得任何其他颜色，无论我输入什么值。我试过 colorWithHue:Saturation:Brightness 并且我有同样的问题。

The values for red green and blue should be beween 0.0 and 1.0. From UIColor doc:
红色绿色和蓝色的值应介于 0.0 和 1.0 之间。来自 UIColor 文档：
Values below 0.0 are interpreted as 0.0, and values above 1.0 are interpreted as 1.0.
低于 0.0 的值被解释为 0.0，高于 1.0 的值被解释为 1.0。
