iOS Setting CGFillColor from UIColor

[Duke Leto]

I have a UIColor, and I want to use it for the CGContextSetFillColor() method. I tried

CGColorRef fillColor = [theColor CGColor];
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColor(context, fillColor);

The problem is a warning saying
"passing argument 2 of 'CGContextSetFillColor' from incompatible pointer type"

How can I use the UIColor to set my fill color?

Try using CGContextSetFillColorWithColor instead.

Now I don't have any warnings, but when I try to set a CGColorRef to [theColor CGColor], the application crashes.


Another thing I found: this only happens when I make the color with [UIColor colorWithRed:Blue:Green:Alpha];, but if I use [UIColor cyanColor] or something, it works.

How is theColor defined?

 

[Duke Leto]

With [UIColor colorWithRed:blue:green];

 

[Duke Leto]

Is there any way to create a custom color that can become a CGColorRef?

 

[phjo]

why not do [theColor setFill]; instead ?

Wow, I can't believe I didn't think of that!
