iphone - How do I get the value (float) for RG & B of a UIColor object? -


I have created a UIColor object and want to set the color before using CGContextSetRGBStrokeColor. To do this, I need to remove the red, green and blue values ​​from the UIColor object. How do I do that?

Or maybe using any other method is a better way of defining color (when I saw it for this), in which I can use the UIColor object to set the color ?

Thank you in advance!

You do not need RGB components in your case. Simply use CGContextSetRGBStrokeColor instead. 

  CGContextSetStrokeColorWithColor (references, thatUIColor.CGColor);

(To get RGB components, see.)
