I'm creating a drawing app and I would like to integrate NKO-Colour-Picker but the problem is I would like to use the UIColor from the picker as the stroke colour when a user draws on my UIView.

How would I do this as CGContextSetRGBStrokeColor is coded in RGB values not UIColor?

I currently have this:

CGContextSetRGBStrokeColor(UIGraphicsGetCurrentContext(), red, green, blue, 1);

Any help would be appreciated.

有帮助吗?

解决方案

Use:

UIColor *color = ... // your selected color
CGContextSetStrokeColorWithColor(UIGraphicsGetCurrentContext(), color.CGColor);

or simply do:

[color set];

or:

[color setStroke];
